Looking back on my first video I think our testing was solid. Fact is, touching the relay disturbed the box (making the connection) and gave us a false sense of the repair. THE GOOD NEWS is we had solid testing so when the vehicle came back we knew what we did previously and exactly where to begin. If there was no testing performed previously we would still be flying blind at this point. This is why I try to stress to you folks to carry out the best method you can and be minimally invasive when dealing with an intermittents. As I proved, "touching" something can hide the real issue. Hope it all makes sense in the end. -Eric O.
Yep, if you did good testing you already have a foundation as to where to look. The old "miracle touch" can drive you bonkers. Watched both vids, you did test and voltage was there. I'm guessing there were a couple of strands left and that was enough to usually trigger the low current relay. Then it rotted some more and failed. Switching the charger likely dropped the voltage and now that the battery had a better charge the second you switched it was enough to trigger the relay from the momentary voltage spike from the unloaded charger.
Eric, your first go round was flawless. The intermittent connection remade itself and so the problem was gone. Intermittent problems are the worst! Keep the faith buddy.
I know you hate fixing these issues but that's you have to pay for the excitement of the chase which is the best adrenaline rush for a diagnostic mechanic 😂😢😮🎉 then the pain sets in as you have the task of the repair
Wow Sasha Ramirez u may want to be his data file organizer . Good job. In his defense. I was sick for over 2 weeks an now things from before tht time seem foggy and forgot some stuff. Craziest thing ever . Like a hangover from a late night of partying.
Intermittent issues are the worst. They will make you cuss and think about a career change. You did well on this diag and repair my man. Hold your head high.
I have been an electronics repair technician for almost 45 years. Intermittent issues happen. Multiple failure points happen. Multiple Intermittent failures happen. They'll drive you to question yourself. I started testing repairs by picking up and dropping the item repeatedly to see if there weren't hidden issues that would reveal themselves down the road. If you work long enough you're going to run into stuff like this. Congratulations on your sticking with it and fixing it. Well done
Computer programmer here --> I do this with code too "I started testing repairs by picking up and dropping the item repeatedly". After a while you develop a really nasty set of test cases.
I found once you disturb the connection and everything starts working just leave it on the bench and come back after a while and the issue has resurfaced.
The one that drives me mad is the (Works until the case cover is on and screws are in.) Then it fails. Often it's a hairline crack on the pcb and the case dares to move the pcb slightly.
The first shop was actually correct in their diagnosis. But, they didn't want to make the effort to find out why the fuse box was bad. They would have replaced the entire fuse box and wire harness. That would have cost a fortune. As a repair technician for 40 years in the mainframe computer industry, I commend your troubleshooting techniques and your tenacity. Job well done!
@@cjr1881 Say that fuse box really IS $125, which I doubt it is. As you saw in this video, there are literally zero connectors that connect the wires to that fuse box. As others here said that makes the fuse box something that is not serviceable to the tech. So if you actually found someone willing to take this job on, the tech would have to remove the pins from every single terminal in that existing fuse box and accurately put them onto the new fuse box. An hour or two labor my ass, and the risk of human error is very high. Not to mention that if they don't see the problem wire in the first place they go to all that effort and thing thing is still broken.
The fact that this fella brought his truck back to you says a lot about the trust he has for you. I wish I could find a mechanic that I could trust 1/2 as much in my area. We all miss things from time to time. However, without trust you never get a second chance.
Back in the 50's started going on TV repair calls with my dad when I was about 10. Mid 60's USAF started my career in computer repair. That was when a single computer took up a full portion of the building and you stood inside it to work on it. Retired a few years back, but I can tell you there is NOTHING worse than an intermittent wire to troubleshoot. The first GE mainframe I worked on had huge racks (3 per bay) that the outside racks had to be swung open to troubleshoot the center rack. Problem was all the inter-rack wiring was not designed to be flexed multiple times. By the time the thing was 5 years old, we were instructed to never open a bay unless there was no other way to troubleshoot the original problem. The computer in question was used to detect and plot intercepts of aircraft that violated the East/West German border. Not exactly a piece of gear you wanted out of service for any length of time. Wonder how all my friends would have slept knowing that 25% of the entire 3 years I was overseas the most critical air defense system in Germany was being maintained by me.
here a broken or bare wire, there a broken or bare wire, everywhere a broken or bare wire. lesson one of anything electrical or electronic, hands off! but sadly, just vibrations of natural daily things effects it all and will cause issues anyway.
Lol now that type of computing power is in the palm of your hand. When I was 7 back in 1967 I walked into UD university of Dayton collage campus the room was full of giant reel to reel tape players this room was the size of 3 football fields The most that computer could do was add 2+2. And it took it an hour to figure it out.
YOU DIDN'T DO ANYTHING WRONG ERIC! You specifically said in the previous video of this pickup that if it happen to come back with the same issue after replacing the relay that you would immediately know the problem was on the control side. Quit beating yourself up man. You followed through,fixed the problem and have another happy customer. Job well done!
Yea, I went back and double checked. He had 2 powers on the relay contacts then. What must have happened is that the crappy wire was JUST barely making contact, showing voltage, but when wiggled slightly from moving the relay, it had no current carrying ability, and the voltage drops out. He had no way of knowing that at the time, because every time he measured that control power, it was there! This time, it was broken enough that it was gone completely when measured, and that lead him to the broken wire. The process was good and correct, he was just unlucky basically. The crappy wire won the battle, but Eric O won the war!
Eric, although its a pain in the hoo haa either way, removing the driver side wheel well liner gives beautiful access to the bottom of the fuse box. I usually will do that if I have to track a wire issue like this so the fuse box is undisturbed for troubleshooting.
I had a day and job just like this today, but a toyota. PITA to get it up and apart enough to test. I feel your pain! The fact the truck came back with the same symptoms, and you still made and posted a video, shows the quality of your character. To be admired for sure.
Please don't quit!!!!! You are the best electrical mechanic I have ever seen and I only wish that at 74 I could figure out the stuff that you do. Keep up these great videos , Who knows , maybe I can still learn something ??
You are my favorite auto technician on UA-cam. A real professional without all the profanity that some use. I've always hated working on Ford's for the kind of stuff they do. They don't consider the technician when they design stuff.
Dude your a great mechanic. I’m in tech school to be a mechanic and your videos inspire me. The stuff I’ve Learned in school doesn’t even really click till I watch you do it. Keep your head up. You’ve been doing this a long time. You know what you’re doing.
Great job on making it right 👍. I would think I'm speaking for 99% of your subscribers taking a vehicle to sma the job will be done right. And for me that's priceless.
That is why I feel I must be a DYI'er. Around where I live if you want it done to your complete satisfaction, you better do it yourself. Tried to take mine to SMA one time, when I was in the area. SMA just stays too busy, and we know why. :)
How about chasing a thermal intermittent on a CCTV balun on top of a utility pole while the wind is blowing about 40 mph? I, too am a (now-retired) technician and I forgot the basics for a minute until it all came back to me. Broken wire two inches back inside the jacket that would expand (circuit good) during the day and contract (open circuit) at night. Frustrating, but solved. Now, it's time to go drink a cold NON-ANHESUER BUSCH beer.
Intermittent problems like this are the pits. Your diagnosis was spot on. “There’s the broken wire we are looking for…” The wire was probably damaged during assembly. After years of vibration and temperature cycling it finally broke.
Don’t quit, you’re one of the best out there. The fact that you found the problem and fixed it is testimony to your abilities as a mechanic. Your videos are invaluable to us all. 👍👍👍👍👍👍
Don't give up! The auto industry needs people like you. Unfortunately or fortunately, however you wish to look at it, you are probably one in a thousand "technicians" that has the knowledge and ability to diagnose these intermittent problems. Good job Eric!
When I have a crappy day at work, I just try to remind myself that everyday is an adventure. And it ultimately feels good when you finally get it done.
I've been a electrical troubleshooter in a industrial complex for 40 + years and the only thing I say about an intermittent problem, is time will tell if it is fixed or it comes back. I think your logic is always great. Thanks for all your videos, and one gets by you, it shows you are human, after all.
DON"T kick yourself for the return issue I recall you did everything right and your assumption of having power to that second terminal was right. I had a mechanic take four months to chase down a bad wire in a engine wire harness. Cool new tool.
Hi Eric and the lovely Mrs. O., Well well, so you are human. In the last video you tried a relay and said let him run it and see what happens, well looks like you didn't misdiagnose anything. You said first thing it's probably in the fuse box. You deserve more credit than you give yourself, but I guess that's why all these shops send you their problems because you're the best and humble. Great job buddy!!
There is a real possibility that a broken wire could have damaged the relay by over-working and arcing the contacts. That's my story, and I'm sticking to it!
Sometimes the frustration will make us make bad diagnosis and possibly miss the obviously problem! We’ve all had that happen ! You did a fabulous job in tracking down the problem and repairing it! This was a 1 in 10,000 problem! As you stated in the 1st video that the dealership said needed a new fuse box!! I’ve learned that you aren’t afraid to think outside the box!
Eric, I'm a 70 year old "FOSSIL" electronics tech / Shade Tree. One of the hardest intermittent problems to find is a poor connection. Like you said, the only load on that 10 AMP fuse was the relay coil? So that particular circuit was a load of DAMN NEAR NOTHING ! BTW, I liked the relay tester. Years ago when I worked in manufacturing, we built several pieces of test gear that allowed us to access signals in circuit without having to dismantle EVERYTHING. I also agree with your assessment of FORD trucks. HORRIBLE to access that Fuse box ...
As a 26 year old mechanic with 30 years experience I always go straight to the broken wire under the fuse box... just messing with ya keep up the awesome work you've helped me keep the parts cannon in the safe many times
Don't give up, everyone has bad days, im 99 percent sure you checked all that on first video. You're my favorite guy on UA-cam, if you quit then what will I watch!!😂😊
We all understand the frustration with this repair. Manufactures dont give a rip about repair after assembly. They want to get it together as fast as possible and out the door. Thanks for showing us the frustration of this repair. We feel your pain at sometime or another with auto repair. Please keep showing us the real side of repairs. Thanks Mr O
Your are so patient compared to what I would be. Mother lover is nice compared to what I would call it. Also you are more like an electrical engineer rather than a mechanic! Keep up the great work. I so much look forward to your videos because 90% of the time I learn something. Lol so it off camera because you are gonna swear a little bit I love it
Intermittent problems are the hardest type to fix, and you did have control voltage the first time. Don't beat yourself up I doubt if many others would have found it better than you did. Keep up the good work!
Eric don't forget that on that first video you were not feeling well, so things like this happen, just don't be so hard on your self.We all still love your videos.
You are one of the best automotive mechanics out there…. Appreciate your ability to be self critical and honest. Great work… wish you were closer to Connecticut
Pull the fender well. I work on lots of these trucks. In fleet trucks the fuse box cover is almost always gone. I kinda laughed a little when I saw you had to pull it. First time is very frustrating it feels like its going to come out, but it doesn’t!
eric, the fact that you repair as many vehicles you do on a daily basis by yourself makes you a better mechanic than most. with bad designs of spaghetti messes like ford makes, stupid crap is bound to happen. unlike some other wrench turners, you didnt get on the pitypot, stuck with the task at hand and made a customer happy despite idiots at ford. thanks for all the work you do to bring us your videos. been watching since 40k subs and my knowledge of repairing vehicles have grown thanks to you.
Damn, dude! Last I checked, you're human. It's impossible to fix a vehicle without touching it. Things do move/vibrate when being driven even in a Bentley let alone a bucking bronco like an F250. We STILL love you.
All the respect to your work ethics I enjoy watching your videos I am also a mechanic I love complex cases , it feels good when you solve issues others couldn’t …
Eric O. don’t get discouraged! You’re kicking butt and teaching all of us every day. Thank you for sharing your process with us. Any other shop would have had this guy in the hole whole for an entire harness and an ECU. You rock!
Whenever that happens to me I call it "unbroken" instead of "fixed". It happens to me way to often that something isn't working and before I diagnose it, the problem is fixed, so I started saying "I didn't fix it, I unbroken it". Much love to you are your family Eric! 🤘🤘🤘
Eric O. - you are a mechanical Dr House as far as I’m concerned. Never give up! You have to be one of the best techs I have ever seen and a bit of an automotive hero to me. Mistake or not your diagnostic work is always on point!!
Hey Eric. I’ve work on these quite a bit up on the Alaskan oil field. The best way that I’ve found to access the bottom of the box is by dropping the wheel liner and then you can have it hang low enough to work on. I had this very ckt rub through behind the left headlight housing. Too late now but easier next time. Thanks for posting the vids even though you were ticked about it. It is super lame that Ford doesn’t make it serviceable or even easy to access for that matter.
Well done finding that, I watched your other vid on this and I seriously don't think you misdiagnosed it. The rats nest under the fuse board could have hidden many special secrets and you took your time to find it. Good on ya Eric. Top job as normal.
So I’ve been watching your videos for a few months now and your trouble shooting skills are impeccable. I have learned a tremendous amount just by watching your vids. Thanks for taking us along on your troubleshooting adventures. BTW…greetings from South Texas and I don’t mean San Antonio. lol
If My memory serves me, in your first video on this truck, the owner was quoted by another shop or the dealer - a new fuse box. That would have been a much more expensive repair. So, the reality is you did a solid for your customer. And you stand behind your work. I suspect he will be a repeat customer now. Thanks for sharing this one with us.
I had a 250 for about 3 weeks intermittent stall and battery drain. Turns out the 3rd brake light was leaking during moderate rain soaking the RTM and waking errything up.
Eric: You didn't mess up. You are only human. Don't beat yourself up. Most likely, when tracing the problem the first time, you had the midas touch and "fixed it" (aka erased the failure) but now you found the "real" (or likely main problem but fixed the secondary problem first) problem. I admire your smarts. If I was half as smart as you, I would be a millionaire.
That control wire, when it was making a connection, was still probably at a reduced voltage (even for a low draw on the relay coil) could have been too weak to close the relay contacts enough to prevent arcing/deterioration of the contacts (I know you took a brief look at them), and could have made the relay just as unreliable as the broken wire... I'd be curious to take little closer look at the old relay, if it wasn't long gone in the trash.
I also thought the same thing. Many times electrical problem nightmares are the hidden wires under fuse/relay box due to either corrosion or broken wires. First time I have ever seen Eric get really pissed with the job he was doing.
Sometimes you're way too hard on yourself but that's what makes you an honest guy also! Feel good that you didn't throw the parts cannon at the problem like the other shop that would cost your customer a lot of money! Keep your head up and thanks for what you do!
Watching you brings back nightmares. I truly believe Ford electrics/electronics is a strange world that only Ford coolaid drinkers understand. What ever you charge "ITS NOT ENOUGH "😊
After recently watching your first video, I think your first fix was correct, I don’t need to tell you that it’s possible to have two issues on the same problem, unfortunately, do you think the customer would believe you, I doubt it. Good job Eric as usual 👍🏴
I’ll tell ya, you’re a hell of a mechanic Eric. If I couldn’t figure out a problem with my vehicle, and I lived in the PRNY, I’d definitely be bringing it to your shop. Especially with the dedication you have to your trade. You can tell you’re dedicated too because if you weren’t it wouldn’t piss you off so bad to have something come back. 👍🏻👍🏻👍🏻
Eric O. is awesome! Considering the amount of electronics in today's vehicles, I hope most other technicians are being provided with an electronics-based automotive training. Electrical systems were so rudimentary when I received automotive training in the '70s, I wound up attending an electronics school to learn. I hope that has changed.
Honestly, hearing Eric O. beat himself up over something which he is an expert made me feel better about myself doing the same thing when I mess up. It's nice to see you're human and brave enough to not edit it out.
Great video! It seemed like the first time you had a separate issue, it happens. With the customer smacking the box to get it to run, it would work with both of these issues. Good job!
In the phone business we called those type of faults "High joint opens", or "Dirty opens", or "High resistance opens". They can cause you to chase your tail.
Eric, love your persistence and logical approach. The only thing that you noticed in the first video that concerned me was that the old relay looked and worked really well. You noted a little crustiness on the contacts, but really it wasn't that bad. So that was almost maybe, possibly, perhaps, not-out-of-this-world...a clue that there was maybe another cause. In the end, you found the culprit...of course! So proud of the example you set for all your viewers--young and old. Best wishes for continued success from Florida.
He had power on the control in the first video, so the wire was not completely broken. The intermittent nature of the bad wire could also negatively impact the relay. It probably should be replaced and without an absence of control power it would be the logical culprit. If you want to be accurate the dealership recommendation to replace the fuse box which includes both the relay and the wiring harness would have been the fastest repair and possibly the most cost effective given the tow and time spent. However it wasnt available as he stated originally so this is what he had to do.
The relay fix from the last video didn't make sense to me. And seemed kinda rushed. This time you showed something broken and repaired it. I watch you to learn from you and I appreciate your content thanks for sharing your experience with us all.
Hello Eric, nice teaching lesson for all of us, your persistent is incredible. The other shop gives up so fast. But you didn't the problems may have been related to each other just by being right next to each other .your diagnosis was right the first time. And your diagnosis the second time was right. You are a terrific auto tech, and we must learn these lessons from you. Take care, thanks 😊...
Well it was the same leg that was flickering, thats why the other shop didn't want to change the fuse box. Lol. The other shop has No dangles down below to repair like you do so very well. Outstanding Eric.
You didn't misdiagnose anything, you did what any honest guy would do and you went with the most obvious answer on the 1st video and not only that you properly tested the circuits as you always do. It's an intermittent how much time do you want to bill? Relay is cheaper than labor regardless. I thought this was an excellent video series; so thanks a lot for sharing it with us Eric; hope all is well and I'm glad to see you're feeling better. God bless brother 🙌 🙏 Let's go Brandon 😂
It was a difficult problem to find. Intermittant problems can have you chasing yourself in circles. He got there in the end and it would have saved the customer a wiring loom replacement at another garage. Eric's method does work. 👍Didin't help that he had a cold.
intermittents can be a real ass-kicker especially if you aren't able to reliably duplicate the symptoms, nothing will stress your competence at electrical troubleshooting than chasing intermittents, it always seems so simple when you find the root cause but my god the path to get there. Great to see a guy doing his due diligence and taking care of customers, this is a great video, we need more guys like you.
Yessss, I was hoping we would get the real deal later. BTW Eric O, even on your worst day you are a far better Technician than most on their best day. It's hard to find ones that don't immediately fall onto the parts cannon button. Real Techs get to the root cause. I love your channel because I was an Avionics Tech in the Navy and this brings back some awesome memories and let's me keep my skills up.I always love when something electrical breaks at my house. Gives me something to tinker with.
Looking back on my first video I think our testing was solid. Fact is, touching the relay disturbed the box (making the connection) and gave us a false sense of the repair. THE GOOD NEWS is we had solid testing so when the vehicle came back we knew what we did previously and exactly where to begin.

just like you eric, i hated going into the fuse box on modern cars, the places they put them is just silly, a broken wire can drive you crazy...

You are’the man ‘the explorer in you makes you awesome.
If that’s the biggest thing you’ve missed, you’re doing better than 99% of mechanics out there.
I still think he should quit being a mechanic like he said. What good is he anyway? ;) ........

Yep gotta love the irony there. Good work Eric.
It says a fuse box is $125 and an hour or two labor. Nice try. Would have been fixed a month ago and probably cheaper than what Eric charged.
@@cjr1881 what is "it"?
I find that very hard to believe.
Maybe for the cover, sure.
Maybe for the shell, but I doubt even that.

Now, it's time to go drink a cold NON-ANHESUER BUSCH beer.
👍
No other mechanic would have opened Pandora’s box. You the man. Don’t ever give up.
Intermittent problems like this are the pits. Your diagnosis was spot on. “There’s the broken wire we are looking for…” The wire was probably damaged during assembly. After years of vibration and temperature cycling it finally broke.
Don’t quit, you’re one of the best out there. The fact that you found the problem and fixed it is testimony to your abilities as a mechanic. Your videos are invaluable to us all. 👍👍👍👍👍👍
Eric is the right man for the job always on the ball
Don't give up! The auto industry needs people like you. Unfortunately or fortunately, however you wish to look at it, you are probably one in a thousand "technicians" that has the knowledge and ability to diagnose these intermittent problems. Good job Eric!
Now we know why most shops won’t touch intermittent issues!
OOOOOOOOHMMMM!!!!! all good bro.
When I have a crappy day at work, I just try to remind myself that everyday is an adventure. And it ultimately feels good when you finally get it done.
"give it flying lessons" is now my favorite phrase of describing several parts that have frustrated me before...
I've been a electrical troubleshooter in a industrial complex for 40 + years and the only thing I say about an intermittent problem, is time will tell if it is fixed or it comes back.
I think your logic is always great. Thanks for all your videos, and one gets by you, it shows you are human, after all.
What a joy fixing something that acts up once a month.
You displayed your professionalism by sticking it out and refusing to quit until the problem was found and solved.
Tenacity is the champ.
DON"T kick yourself for the return issue I recall you did everything right and your assumption of having power to that second terminal was right. I had a mechanic take four months to chase down a bad wire in a engine wire harness. Cool new tool.
The two videos that make up this case study were a very informative case study for me. I'm glad Mr. O decided to upload them.
After 40 plus years as an auto Tech I feel your frustration.........great job finding and fixing the problem ! ! ! ! 👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Hi Eric and the lovely Mrs. O., Well well, so you are human. In the last video you tried a relay and said let him run it and see what happens, well looks like you didn't misdiagnose anything. You said first thing it's probably in the fuse box. You deserve more credit than you give yourself, but I guess that's why all these shops send you their problems because you're the best and humble. Great job buddy!!
There is a real possibility that a broken wire could have damaged the relay by over-working and arcing the contacts. That's my story, and I'm sticking to it!
Every once in a while you get one that gets you flustered. Yours was a f-250. Great job keeping your cool.
Sometimes the frustration will make us make bad diagnosis and possibly miss the obviously problem! We’ve all had that happen ! You did a fabulous job in tracking down the problem and repairing it! This was a 1 in 10,000 problem! As you stated in the 1st video that the dealership said needed a new fuse box!! I’ve learned that you aren’t afraid to think outside the box!
Eric, I'm a 70 year old "FOSSIL" electronics tech / Shade Tree. One of the hardest intermittent problems to find is a poor connection. Like you said, the only load on that 10 AMP fuse was the relay coil? So that particular circuit was a load of DAMN NEAR NOTHING ! BTW, I liked the relay tester. Years ago when I worked in manufacturing, we built several pieces of test gear that allowed us to access signals in circuit without having to dismantle EVERYTHING. I also agree with your assessment of FORD trucks. HORRIBLE to access that Fuse box ...
Unbelievable what you have to go through. I admire your talent despite the off camera words. I would NEVER have the patience to do what you do.
Wouldn't have been the first time I drilled a hole through something and installed an outside fuse!LOL!
You still are always on point...you fixed it man!
As a 26 year old mechanic with 30 years experience I always go straight to the broken wire under the fuse box... just messing with ya keep up the awesome work you've helped me keep the parts cannon in the safe many times
So you start be mechanic even before you are born. wow.
@@zell863 whooosh
Was born with a ratchet on his baby 🍼... awesomeness 😅
@@zell863 exactly tells me he is capping and lying
Don't give up, everyone has bad days, im 99 percent sure you checked all that on first video. You're my favorite guy on UA-cam, if you quit then what will I watch!!😂😊
We all understand the frustration with this repair. Manufactures dont give a rip about repair after assembly. They want to get it together as fast as possible and out the door. Thanks for showing us the frustration of this repair. We feel your pain at sometime or another with auto repair. Please keep showing us the real side of repairs. Thanks Mr O
This is so real, so many of us can relate to the frustration. Love the line about giving the fuse box lid flying lessons. 😂
But Mr O missed threatening to introduce his fist to the engineer that designed it. I would have. Well done Eric
Your are so patient compared to what I would be. Mother lover is nice compared to what I would call it.
Also you are more like an electrical engineer rather than a mechanic! Keep up the great work. I so much look forward to your videos because 90% of the time I learn something.
Lol so it off camera because you are gonna swear a little bit I love it
It's a Ferd in the rust belt, your procedure was correct, it just had crusties. Nice find Eric.
Intermittent problems are the hardest type to fix, and you did have control voltage the first time. Don't beat yourself up I doubt if many others would have found it better than you did. Keep up the good work!
When You can talk to Yourself, Talk to viewers all at the same time you have talent. Great Vids!
I would not even know where to start. Hats off to you for your persitance and ingenuity.
Eric,very much thanks for keeping this channel a Family channel 😊😊
Eric don't forget that on that first video you were not feeling well, so things like this happen, just don't be so hard on your self.We all still love your videos.
Good one for increasing your views! Now I have to go back and rewatch the firsr video to see if You checked that power on the load side.
You are one of the best automotive mechanics out there…. Appreciate your ability to be self critical and honest. Great work… wish you were closer to Connecticut
resisting the temptation to use a jumper wire for a repair. Nice work Eric.
Pull the fender well. I work on lots of these trucks. In fleet trucks the fuse box cover is almost always gone. I kinda laughed a little when I saw you had to pull it. First time is very frustrating it feels like its going to come out, but it doesn’t!
SMA's 'autopsy' of the factory relay, looked mint condition and clean. Enjoying the Ford !
eric, the fact that you repair as many vehicles you do on a daily basis by yourself makes you a better mechanic than most. with bad designs of spaghetti messes like ford makes, stupid crap is bound to happen. unlike some other wrench turners, you didnt get on the pitypot, stuck with the task at hand and made a customer happy despite idiots at ford.
thanks for all the work you do to bring us your videos. been watching since 40k subs and my knowledge of repairing vehicles have grown thanks to you.
Damn, dude! Last I checked, you're human. It's impossible to fix a vehicle without touching it. Things do move/vibrate when being driven even in a Bentley let alone a bucking bronco like an F250. We STILL love you.
All the respect to your work ethics I enjoy watching your videos I am also a mechanic I love complex cases , it feels good when you solve issues others couldn’t …
Eric O. don’t get discouraged! You’re kicking butt and teaching all of us every day. Thank you for sharing your process with us. Any other shop would have had this guy in the hole whole for an entire harness and an ECU. You rock!
the way Eric closes out his videos tells a lot about how much he enjoyed the job. This was clearly one he hated.
Whenever that happens to me I call it "unbroken" instead of "fixed". It happens to me way to often that something isn't working and before I diagnose it, the problem is fixed, so I started saying "I didn't fix it, I unbroken it". Much love to you are your family Eric! 🤘🤘🤘
I feel for you, I felt like quiting last week, we all have those crap jobs,
Eric O. - you are a mechanical Dr House as far as I’m concerned. Never give up! You have to be one of the best techs I have ever seen and a bit of an automotive hero to me. Mistake or not your diagnostic work is always on point!!
2000 likes says you’re doing it right, we all have had the “straw that broke the camels back time” but you got it done!
Hey Eric. I’ve work on these quite a bit up on the Alaskan oil field. The best way that I’ve found to access the bottom of the box is by dropping the wheel liner and then you can have it hang low enough to work on. I had this very ckt rub through behind the left headlight housing. Too late now but easier next time. Thanks for posting the vids even though you were ticked about it. It is super lame that Ford doesn’t make it serviceable or even easy to access for that matter.
Your pain makes great entertaining videos. Keep up the good work 👍
Well done finding that, I watched your other vid on this and I seriously don't think you misdiagnosed it. The rats nest under the fuse board could have hidden many special secrets and you took your time to find it. Good on ya Eric. Top job as normal.
No young fella , don't dis yourself , I'm 15 years into this longer than you and you know 10 x than I ever will . Thanks for what you do .
I'm pretty sure I remember you checking for both power and grounds on that relay. You did everything right. Just a rare anomaly
I feelya...Mama said there would be days like this..!!
So I’ve been watching your videos for a few months now and your trouble shooting skills are impeccable. I have learned a tremendous amount just by watching your vids. Thanks for taking us along on your troubleshooting adventures. BTW…greetings from South Texas and I don’t mean San Antonio. lol
If My memory serves me, in your first video on this truck, the owner was quoted by another shop or the dealer - a new fuse box. That would have been a much more expensive repair. So, the reality is you did a solid for your customer. And you stand behind your work. I suspect he will be a repeat customer now. Thanks for sharing this one with us.
I had a 250 for about 3 weeks intermittent stall and battery drain. Turns out the 3rd brake light was leaking during moderate rain soaking the RTM and waking errything up.
Eric: You didn't mess up. You are only human. Don't beat yourself up. Most likely, when tracing the problem the first time, you had the midas touch and "fixed it" (aka erased the failure) but now you found the "real" (or likely main problem but fixed the secondary problem first) problem. I admire your smarts. If I was half as smart as you, I would be a millionaire.
That control wire, when it was making a connection, was still probably at a reduced voltage (even for a low draw on the relay coil) could have been too weak to close the relay contacts enough to prevent arcing/deterioration of the contacts (I know you took a brief look at them), and could have made the relay just as unreliable as the broken wire... I'd be curious to take little closer look at the old relay, if it wasn't long gone in the trash.
You see the old relay (a bit) in the first video
He opened the old relay in the previous video. No visual signs of failure.
Mr. O, there be days like this then there are great days. I was a heavy mechanic for 32 years so I know your pain
After your 2nd diagnosis, I said the same thing, as you suspected the problem was under the box. Good job, Mr. O 👍🏾
I also thought the same thing. Many times electrical problem nightmares are the hidden wires under fuse/relay box due to either corrosion or broken wires. First time I have ever seen Eric get really pissed with the job he was doing.
You didn’t miss it Eric. Control power was present at your first pass. All good. All indicators were the relay. As you were.
Sometimes you're way too hard on yourself but that's what makes you an honest guy also! Feel good that you didn't throw the parts cannon at the problem like the other shop that would cost your customer a lot of money! Keep your head up and thanks for what you do!
Watching you brings back nightmares. I truly believe Ford electrics/electronics is a strange world that only Ford coolaid drinkers understand. What ever you charge "ITS NOT ENOUGH "😊
After recently watching your first video, I think your first fix was correct, I don’t need to tell you that it’s possible to have two issues on the same problem, unfortunately, do you think the customer would believe you, I doubt it.
Good job Eric as usual 👍🏴
#1 rule in diagnosing, you won't win them all. Great content.
#1 rule on diagnosing. Follow the facts and you WILL always win 👍
I’ll tell ya, you’re a hell of a mechanic Eric. If I couldn’t figure out a problem with my vehicle, and I lived in the PRNY, I’d definitely be bringing it to your shop. Especially with the dedication you have to your trade. You can tell you’re dedicated too because if you weren’t it wouldn’t piss you off so bad to have something come back. 👍🏻👍🏻👍🏻
Agreed! SMA (Eric O) is still where I'd take my vehicle problems to get healed.
Mechanic? Well in this case electrical technician HAHA!!!
Hell of a job you did. Enjoy your videos.
Eric O. is awesome! Considering the amount of electronics in today's vehicles, I hope most other technicians are being provided with an electronics-based automotive training. Electrical systems were so rudimentary when I received automotive training in the '70s, I wound up attending an electronics school to learn. I hope that has changed.
Honestly, hearing Eric O. beat himself up over something which he is an expert made me feel better about myself doing the same thing when I mess up. It's nice to see you're human and brave enough to not edit it out.
Great video! It seemed like the first time you had a separate issue, it happens. With the customer smacking the box to get it to run, it would work with both of these issues. Good job!
In the phone business we called those type of faults "High joint opens", or "Dirty opens", or "High resistance opens". They can cause you to chase your tail.
Eric, love your persistence and logical approach. The only thing that you noticed in the first video that concerned me was that the old relay looked and worked really well. You noted a little crustiness on the contacts, but really it wasn't that bad. So that was almost maybe, possibly, perhaps, not-out-of-this-world...a clue that there was maybe another cause. In the end, you found the culprit...of course! So proud of the example you set for all your viewers--young and old. Best wishes for continued success from Florida.
He had power on the control in the first video, so the wire was not completely broken. The intermittent nature of the bad wire could also negatively impact the relay. It probably should be replaced and without an absence of control power it would be the logical culprit. If you want to be accurate the dealership recommendation to replace the fuse box which includes both the relay and the wiring harness would have been the fastest repair and possibly the most cost effective given the tow and time spent. However it wasnt available as he stated originally so this is what he had to do.
The relay fix from the last video didn't make sense to me. And seemed kinda rushed. This time you showed something broken and repaired it. I watch you to learn from you and I appreciate your content thanks for sharing your experience with us all.
Hello Eric, nice teaching lesson for all of us, your persistent is incredible. The other shop gives up so fast. But you didn't the problems may have been related to each other just by being right next to each other .your diagnosis was right the first time. And your diagnosis the second time was right. You are a terrific auto tech, and we must learn these lessons from you. Take care, thanks 😊...
I hada feeling when it "fixed" itself after touching that relay this story wasn't over. Like you say, follow the process!
The good news is that after a rough day, you can go home and dig out a stump to get rid of all that frustration.😉👍
Well it was the same leg that was flickering, thats why the other shop didn't want to change the fuse box. Lol. The other shop has No dangles down below to repair like you do so very well. Outstanding Eric.
You didn't misdiagnose anything, you did what any honest guy would do and you went with the most obvious answer on the 1st video and not only that you properly tested the circuits as you always do. It's an intermittent how much time do you want to bill? Relay is cheaper than labor regardless. I thought this was an excellent video series; so thanks a lot for sharing it with us Eric; hope all is well and I'm glad to see you're feeling better. God bless brother 🙌 🙏
Let's go Brandon 😂
It was a difficult problem to find. Intermittant problems can have you chasing yourself in circles. He got there in the end and it would have saved the customer a wiring loom replacement at another garage. Eric's method does work. 👍Didin't help that he had a cold.
@@Sean006 Absolutely.
intermittents can be a real ass-kicker especially if you aren't able to reliably duplicate the symptoms, nothing will stress your competence at electrical troubleshooting than chasing intermittents, it always seems so simple when you find the root cause but my god the path to get there. Great to see a guy doing his due diligence and taking care of customers, this is a great video, we need more guys like you.
Yessss, I was hoping we would get the real deal later. BTW Eric O, even on your worst day you are a far better Technician than most on their best day. It's hard to find ones that don't immediately fall onto the parts cannon button. Real Techs get to the root cause. I love your channel because I was an Avionics Tech in the Navy and this brings back some awesome memories and let's me keep my skills up.I always love when something electrical breaks at my house. Gives me something to tinker with.
