McCoy was also the name brand of an automatic oiler that was used on steam engines. They were the best. It's where the phrase. "The real McCoy " comes from.
@19:52 Yup, the old "It worked before I brought it into the shop for other repairs", conundrum! Then you get into the "You're just trying to rip me off" mentality. 💸💸💸😂
McCoy is a very lucky guy working and learning from a true master mechanic like you! You are knowledgeable, honest, and generally nice guy! Honesty is something you don’t see much of any more in New York. I can say that because I am also from the “Peoples Republic of New York! Salt and rust capital of the USA.
And I have to watch out for the dishonesty in the Auto and truck repair shops and dealers in NY when I need to get work done on my vehicles. I know a lie and what BS is but they still try to get over on me. I’m too old to do my own repairs anymore I really have ch to watch what they do! Dealers, independents some are just stupid or untrained idiots others are just dishonest to the bone!
Takes me back to when I first found your channel 5 years ago Eric. My '09 Patriot 2.2D had the corroded ASD relay issue and you helped me locate and solve it for peanuts and time. Been a follower ever since 👍
Good diagnostic, Eric! I noted that it was around minute 5:34, when you were checking pin 85 with the test light, that the LED went full brightness, and you hadn't touched the fuse yet. Maybe it was the relay socket that was making a bad contact.
Agreed. At that point, Eric had his test probe connected to the ground, and when he touched what we would find to be the ground side of the relay, it got bright. I would suspect a bad ground somewhere. If true, it will be back.
Agree with this comment. That relay socket might need a closer look. Love the channel Eric, I've learned a lot. Trying my best to keep my 2003 Ranger (B4000) from rusting away in NH!
Yes it looks like the control ground could have high resistance causing the light to be dim. I also noticed a blip in the light when McCoy switched the ignition I believe. The LED was doing a lot around 7:23
McCoy is a Scottish family name, the family motto was Manu forti, which means "a strong hand". He will find a strong hand very useful in your trade. Staggering to realise I was watching Kirk, Bones, Scotty,Spock and all the rest of the crew over 50 years ago. Of course, excellent video as always.
I'm retired now but spent my career in the west. You run into more green crusty stuff in 1 month than I did in several years. I enjoy watching you working through the process. Must watch stuff for anyone looking at turning wrenches for a living. Also, good call not touching things unrelated to the original complaint but taking notes and informing the customer of potential future problems.
Me retired too. Coastal driven cars in California can over time develope green krusties only less pronounced. Have found hidden high resistance on older classic cars.
DREADED TIPM.our town and country. Nightmare, replaced TIPM twice, fuel pump, ignition switch, various other things, spent over $6,000 and never did find out what it was. Summer time started every time, got cold out and it was hit or miss. Now the wife unit drives a Toyota 😊
My Daughter got real pissed when I told her those Patriots are only good for the scrap yard. Then she found out after $2000.00 in repairs on the electronics and relay box.
Helped a neighbor with a no start last night so she can get to work and it always feels good to hear that baby turn on afterwards . Your channel and Paul’s have helped me a ton your a great teacher .
@@SouthMainAuto I don’t know how much you’re getting off this UA-cam gig, but it’s probably not enough, you’re losing money on your business to make us happy and I’m sure we all appreciate it.
Had literally the same problem, watched your video. Decided to try it out and it worked, thanks. I’m still gonna have to follow up on it, of course, but it got me Home for the day.
@SouthMainAuto 5:34 That is the first instance where your LED fully illuminated. 5:41 It remained bright. At this point you had not touched the TIPM... 6:35 Then there is some tomfoolery with the key... but you were providing ground. But then it stayed bright even after removing ground. I'm not sure what to think about this one yet.
100% correct. The average customer who has been fleeced before by a greedy, unscrupulous shop will more than likely blame you for anything that goes wrong even though it is not related to the initial complaint. If it ain't broke don't fix it, just notify the customer what you found & tell them that it could turn out to be Pandora's box if you fiddle with it. Like you said, "know when to hold them, know when to fold them."
in the airplane service it is common to extract and reinsert fuses and relays, re racking, to prevent green crusties. i do it annually on my motorcycles.
Just surprised today you didn't vaccum all the leaves under the TIPM. Yes, don't mess with this box until is really necessary. Your diagnosis is good Eric.!
The LED went bright and then out at about 6:38 when McCoy turned the ignition off, Seconds later, when he turned the ignition back on, it came on bright, never to be dim again. For what it's worth, that's what it looked like.
Marvellous engineering, its an off-road vehicle, it'll go wading, there will be water down below so that's where we'll put the fuse-box! so glad I own a Land Rover, all my electrics are high up!
Had a 1997 Jeep Grand Cherokee random engine dying. Found and aviation mechanic on utube found the problem ECU cover on engine firewall cover screws too long. All I did was back them off. He put in shorter screws. That did not get into motherboard causing ground. First praise for utube help 🎉
The moment that you fixed it is at 6:30) .. You switched your test light FROM power and had it probed into the power side of the coil and when he cycled the key on and off--- that gave it just enough juice through the test light to break through the corroded connection (wherever it is)---- which then caused your red LED light on the tester to stay bright.. even when you take away the test light. Before that, the little LED was always dim. So we never really found where the "issue" actually was................. You immediately flipped the switch and it worked as normal. You could have just thrown the relay back in there and it would have been done right then. Pulling the fuse and replacing, etc.. may have been the bad connection point, but we don't actually know; it sort of fixed itself before you could find it.
I don't blame You eric because that's exactly what the customer would probably Do, You're done right just on about it and leave it alone. And if he wants to know why then you can just tell him, It's so easy to make more work for yourself and not get paid for it, Good job Eric.
Big AMEN to Deoxit. Treated new server RAM sockets, HDD power & data connections & mainboard power connections with it. Had multiple servers run 24x7x365 for FIFTEEN plus years. Three times Dell's maximum warranty period. Deoxit works.
When you think you've seen everything, something new comes along. As fuses and other electrical parts age, corrosion seems to find a way to coat the connection points almost like it's magnetically attracted. Even in Southern California. I've seen that milky white coating. Hopefully, that's all it was this time. Good one Mr. O.
Great video! The ones that start working when you 'touch' them are the toughest to diagnose!?! I've seen it in brand new equipment, and once I touched them they never acted up again.
I had a 2010 Patriot, same problem, it was in the relay box, one relay was so corroded that a prong broke off. To my understanding it was the rear most and close to fender relay that had the broken prong, but that relay was not in the starting circuit it was one of the middle ones. The broken relay was the relay that feeds power the the middle relay which is the one that was in the starting circuit. Since the broken relay was not sending power to the middle relay the jeep would not start. I actually pulled all the relays out and checked them. Had the jeep towed to my mechanic and asked him to specifically remove the broken prong and replace the damaged relay and that solved the problem. I had the jeep for 2 more years and the problem never repeated itself. But every 4 months I would go into that relay box and inspect and clean all the relays.
I believe that when you review your footage you’ll see that the LED becomes brighter just as McCoy fiddles with the ignition switch to turn it off then back on. I think it’s the ignition switch that has a poor connection especially when it is cold because of hysteresis and all that metallurgy stuff. At least that’s what I saw. Have a great day. 😊
What I've learned from you about electrical car problems: check the battery, check the fuses, and check the grounds. And of course, know how to read a wiring diagram.
Hello Eric When the drag of the fuse is to loose, you can bent the leg of the fuse a little bit… Is always works when jou are out of spares. Or on the rood👍👍
I did.. I was confused when he didn't explain what it was doing. (5:20) - His test light was tied to ground--- and when he tested that ground side (because he thought it was the power side at first), it would light up that little red LED, but not the test light. So for me, that means that the computer was sending a bad/weak ground control-- and he just gave it a good ground through the test light.... That doesn't explain what ultimately fixed it though.??? Maybe the bad connection was at the relay pins and he just scrapped them "clean" with his test adapter box...? He didn't really do anything to fix it--- it worked the first time he manually flipped that switch. So maybe it was just a bad/ stuck relay and that's it; and handling it made it break loose and work again for now.
If it aint broke don't fix it. This lesson I learned the hard way more than once... [TLDR: I helped my roommate replace a part on his car that I determined wasn't broken. I paid dearly for that mistake. In fact, Im still negatively affected today because of it] .... I helped my roommate fix the AC on his car last year. I diagnosed the problem to be a solenoid attached to his compressor. Easy $25 replacement. But no, he wanted to change the entire compressor. I said that's dumb, you don't need to. He said the dealership told him something about the compressor is getting old. I said who cares, they clearly didn't diagnose the problem like I just did and yea they like taking your money. So he ignores me and starts shopping for a compressor. I relented thinking it's not my money, not my car, really it's not my choice. So I text him a link to the correct compressor to buy from Amazon. I based my choice on several things including threads I read on forums specifically addressing his vehicle's AC system. The oem brand part was actually not recommended for a replacement. A certain aftermarket brand was much better. So did my roommate listen to me and buy the one I suggested? Of course not. So he bought the oem brand compressor for more $. So, we remove his old compressor and realize the compressor he bought was not the same. Different pulleys entirely. My roommate insisted it was the correct part. I did a little digging and showed him that he did not buy the right part. His car was the diesel version and he bought the compressor for the gasoline version. Completely different pulleys, but the rest looked identical. Too late to return the compressor now because a couple months already passed. I said hey I don't mind driving you to and from work for a couple weeks until you order the right part. Just ebay the compressor you're stuck with. I even offered to help him do that with my ebay account. I said the only other option is to swap the pulleys which I don't even know is possible and requires special tools. So he rents the special tools from the local parts store to try swapping pulleys. The tools don't fit, we are way too far into the weeds at this point anyway, I say. He continues trying to swap the pulleys. I got fed up. I told him I quit. Which I did. I walked away for 3 days. 3 days later he tells me he wants to try the new compressor anyway with the wrong pulley. I should have told him to fuck himself and I'll only help if you buy what I say to buy. No more bullshit. But I didn't do that. I returned to the garage to assist him. I counted the ribs on the new compressor pulley. I said the pulley has 6 ribs and your belt only has 5. Again I offer him rides so he'll just wait and buy the right part. He says what's the worst that can happen if we run the wrong pulley? I said the serpentine belt might break but that's it. Well we had an extra one of those and they're only $20. He wants to try it. Ok as long as you know I don't recommend this and your belt will definitely break. Ok he says. So we bolt it in and start the car. It ran fine long enough for me to vacuum the refrigerant lines and begin adding coolant. Then the serpentine belt popped. He shut the car off within about 3 seconds of losing the belt. I said "now you see?" So, we switched back to his original compressor and changed the solenoid (remember that was my very first recommendation), and changed the belt. Try again, the car won't start. Turns out his car has a very special problem that is very common for his engine model.(jcaa vw diesel) If the serpentine belt breaks, debris from the busted belt falls into this little void where it gets behind the timing belt where the crank balancer pulley lives. The debris jams the crank pulley enough to jump timing. His engine jumped timing and his valves interfered, hitting the pistons. Of course we had no idea that was even possible from just a broken serpentine belt. So I spent 3 more days trying to get his car to start before he towed it to the dealership. They used a bore camera to photograph the witness marks on the pistons. To this day the asshole never paid me a dollar for some 30 hours of labor and blames me ENTIRELY for breaking his car. 😂😂😂 Three months previous to this AC fiasco, I changed his timing belt FOR FREE and his car ran flawlessly for those 3 months. (That timing belt was an incredibly difficult job to do). He tried saying I botched both jobs! Until I showed him youtube videos of other mechanics dealing with the same broken head due to a failed serpentine belt. Only then did he agree I did the timing belt correctly, but he insists it's my fault the head on his engine broke from messing with the AC compressor. 😂 It's so unreal that I just laugh about it. Remember when I said it's not my money, not my car, what have I got to lose? Well I was wrong. My reputation was to lose. He's told everyone I know that I broke his car. I've missed out on hundreds of dollars of potential work from mutual friends and family since he ruined my reputation. But I'm not a mechanic, I don't own a shop, and it's not enough trouble to sue him over. So his decision to repeatedly ignore my recommendations turned into my problem. That was a very big lesson for me. Dont ever do anyone a "favor" by helping them with their car. You'll become the scapegoat. Either approach it like a mechanic and make all the decisions yourself including which parts to try or buy, or walk away from it.
Good call about not fixing the problems that aren't part or the problem you're after. I once replaced an eyelet on a ground wire on a customer car. I didn't even charge the guy for it. He threw an absolute ass attack. Long story short, lost a customer by trying to be the nice guy.
"A man's got to know his limitations." While I like Dirty Harry, I prefer Platoon..."Feelin goods good enough". You have a feeling not to break something that isn't broken, that good enough for me. Thanks for the video. :)
At 13 minute he comments again about thinking it was dim. Somehow I perfectly moved the slider back to early in the video and by total luck landed EXACTLY on where he's showing the relay box and commenting about how dim the LED is.
I had a similar problem on my old boat with the old style glass fuses. Ignition circuit dead no gauges no engine crank. Checked a punch of things then pulled out the fuse and found while the fuse was not blown & had continuity, the terminal ends were oxidized so no current was flowing. Cleaned fuse box terminals & replaced all the fuses. Really have to replace the old fuse box this season. Simple DC wiring like old cars had so easy to fix….
That sure was a strange onr to be what looked like a good fuse. A good learning point for all of us just because the fuse has power on both sides does not mean that there is a good conection something easily overlooked Cheers Mr O & "Bones" Take the nickname McCoy sounds good.
It was very interesting watching you, you there, hooking up the box looking for a short. I'm not very electrical but, I watch you and Bernie all the time. Awesome..
12 volts cannot " push " past ANY corrosion. The thinest oxide layer will allow CURRENT to pass. This is so common, clean and shiny connection saves the day.
Great diag, Thanks for sharing! it's always a pain when it fixes itself! It seems like the light became bright after he turned the car off and back on before you touched the fuse.(around 6:50) I really wish the uActivate had a built-in relay I would probably use it a lot more.
Yes, that was Clint Eastwood who as San Francisco Police Inspector Harry Callahan said “A man has got to know his limitations” in one of his Dirty Harry movies.

The moment that you fixed it is at 6:30) ..

I believe that when you review your footage you’ll see that the LED becomes brighter just as McCoy fiddles with the ignition switch to turn it off then back on. I think it’s the ignition switch that has a poor connection especially when it is cold because of hysteresis and all that metallurgy stuff. At least that’s what I saw. Have a great day. 😊
Chrysler folks carry spare TIPM's in the back with the spare tire.
What I've learned from you about electrical car problems: check the battery, check the fuses, and check the grounds. And of course, know how to read a wiring diagram.
Hello Eric
When the drag of the fuse is to loose, you can bent the leg of the fuse a little bit…
Is always works when jou are out of spares. Or on the rood👍👍
Or want to crack a fuse.
If it ain't broke... Good call, as usual. Thanx for another good one Mr.O
You didn't notice the light on the tester got brighter when you put the test light in pin 85.
I seen that. I suspect bad ground
Yeah, I thought the same thing.
I did.. I was confused when he didn't explain what it was doing. (5:20) - His test light was tied to ground--- and when he tested that ground side (because he thought it was the power side at first), it would light up that little red LED, but not the test light. So for me, that means that the computer was sending a bad/weak ground control-- and he just gave it a good ground through the test light.... That doesn't explain what ultimately fixed it though.??? Maybe the bad connection was at the relay pins and he just scrapped them "clean" with his test adapter box...? He didn't really do anything to fix it--- it worked the first time he manually flipped that switch. So maybe it was just a bad/ stuck relay and that's it; and handling it made it break loose and work again for now.
It got bright every time McCoy turned the key. He finally noticed when McCoy left it on. He should really look back on this to be sure.
I think that is at about 6:40 when with the test light attached he had McCoy turn the key off and then back on.
The AEWave led light comes on at 5:44 BEFORE you remove fuse 33 at 9:40.
Definitely Clint Eastwood , “man’s got to know his limitations”
"A mans just gotta to know his limitations!" 👍Clint Eastwood
Agreed. We handle those situations like that as well.
If it aint broke don't fix it. This lesson I learned the hard way more than once... [TLDR: I helped my roommate replace a part on his car that I determined wasn't broken. I paid dearly for that mistake. In fact, Im still negatively affected today because of it] .... I helped my roommate fix the AC on his car last year. I diagnosed the problem to be a solenoid attached to his compressor. Easy $25 replacement. But no, he wanted to change the entire compressor. I said that's dumb, you don't need to. He said the dealership told him something about the compressor is getting old. I said who cares, they clearly didn't diagnose the problem like I just did and yea they like taking your money. So he ignores me and starts shopping for a compressor. I relented thinking it's not my money, not my car, really it's not my choice. So I text him a link to the correct compressor to buy from Amazon. I based my choice on several things including threads I read on forums specifically addressing his vehicle's AC system. The oem brand part was actually not recommended for a replacement. A certain aftermarket brand was much better. So did my roommate listen to me and buy the one I suggested? Of course not. So he bought the oem brand compressor for more $. So, we remove his old compressor and realize the compressor he bought was not the same. Different pulleys entirely. My roommate insisted it was the correct part. I did a little digging and showed him that he did not buy the right part. His car was the diesel version and he bought the compressor for the gasoline version. Completely different pulleys, but the rest looked identical. Too late to return the compressor now because a couple months already passed. I said hey I don't mind driving you to and from work for a couple weeks until you order the right part. Just ebay the compressor you're stuck with. I even offered to help him do that with my ebay account. I said the only other option is to swap the pulleys which I don't even know is possible and requires special tools. So he rents the special tools from the local parts store to try swapping pulleys. The tools don't fit, we are way too far into the weeds at this point anyway, I say. He continues trying to swap the pulleys. I got fed up. I told him I quit. Which I did. I walked away for 3 days. 3 days later he tells me he wants to try the new compressor anyway with the wrong pulley. I should have told him to fuck himself and I'll only help if you buy what I say to buy. No more bullshit. But I didn't do that. I returned to the garage to assist him. I counted the ribs on the new compressor pulley. I said the pulley has 6 ribs and your belt only has 5. Again I offer him rides so he'll just wait and buy the right part. He says what's the worst that can happen if we run the wrong pulley? I said the serpentine belt might break but that's it. Well we had an extra one of those and they're only $20. He wants to try it. Ok as long as you know I don't recommend this and your belt will definitely break. Ok he says. So we bolt it in and start the car. It ran fine long enough for me to vacuum the refrigerant lines and begin adding coolant. Then the serpentine belt popped. He shut the car off within about 3 seconds of losing the belt. I said "now you see?" So, we switched back to his original compressor and changed the solenoid (remember that was my very first recommendation), and changed the belt. Try again, the car won't start. Turns out his car has a very special problem that is very common for his engine model.(jcaa vw diesel) If the serpentine belt breaks, debris from the busted belt falls into this little void where it gets behind the timing belt where the crank balancer pulley lives. The debris jams the crank pulley enough to jump timing. His engine jumped timing and his valves interfered, hitting the pistons. Of course we had no idea that was even possible from just a broken serpentine belt. So I spent 3 more days trying to get his car to start before he towed it to the dealership. They used a bore camera to photograph the witness marks on the pistons. To this day the asshole never paid me a dollar for some 30 hours of labor and blames me ENTIRELY for breaking his car. 😂😂😂 Three months previous to this AC fiasco, I changed his timing belt FOR FREE and his car ran flawlessly for those 3 months. (That timing belt was an incredibly difficult job to do). He tried saying I botched both jobs! Until I showed him youtube videos of other mechanics dealing with the same broken head due to a failed serpentine belt. Only then did he agree I did the timing belt correctly, but he insists it's my fault the head on his engine broke from messing with the AC compressor. 😂 It's so unreal that I just laugh about it. Remember when I said it's not my money, not my car, what have I got to lose? Well I was wrong. My reputation was to lose. He's told everyone I know that I broke his car. I've missed out on hundreds of dollars of potential work from mutual friends and family since he ruined my reputation. But I'm not a mechanic, I don't own a shop, and it's not enough trouble to sue him over. So his decision to repeatedly ignore my recommendations turned into my problem. That was a very big lesson for me. Dont ever do anyone a "favor" by helping them with their car. You'll become the scapegoat. Either approach it like a mechanic and make all the decisions yourself including which parts to try or buy, or walk away from it.
Lots of poking and tracing. Hoping no return on the bad connections. Nice to see the thought process.
You fixed the problem that is what you needed to do it runs now
Drinking game every time Eric says McCoy lol
Dude is genius.
Good call about not fixing the problems that aren't part or the problem you're after. I once replaced an eyelet on a ground wire on a customer car. I didn't even charge the guy for it. He threw an absolute ass attack. Long story short, lost a customer by trying to be the nice guy.
Good good, like to see the process.
"A man's got to know his limitations."
While I like Dirty Harry, I prefer Platoon..."Feelin goods good enough". You have a feeling not to break something that isn't broken, that good enough for me.
Thanks for the video. :)
I got one of the original U-activates. Cool little tool .
At 13 minute he comments again about thinking it was dim. Somehow I perfectly moved the slider back to early in the video and by total luck landed EXACTLY on where he's showing the relay box and commenting about how dim the LED is.
I had a similar problem on my old boat with the old style glass fuses. Ignition circuit dead no gauges no engine crank. Checked a punch of things then pulled out the fuse and found while the fuse was not blown & had continuity, the terminal ends were oxidized so no current was flowing. Cleaned fuse box terminals & replaced all the fuses. Really have to replace the old fuse box this season. Simple DC wiring like old cars had so easy to fix….
Awesome job there
That sure was a strange onr to be what looked like a good fuse. A good learning point for all of us just because the fuse has power on both sides does not mean that there is a good conection something easily overlooked Cheers Mr O & "Bones" Take the nickname McCoy sounds good.
It was very interesting watching you, you there, hooking up the box looking for a short. I'm not very electrical but, I watch you and Bernie all the time. Awesome..
12 volts cannot " push " past ANY corrosion. The thinest oxide layer will allow CURRENT to pass. This is so common, clean and shiny connection saves the day.
Great diag, Thanks for sharing! it's always a pain when it fixes itself! It seems like the light became bright after he turned the car off and back on before you touched the fuse.(around 6:50) I really wish the uActivate had a built-in relay I would probably use it a lot more.
Very clear video! Nice catch! We could see the crustiness. Love that you have someone to pass on your wisdom to..... 👍 🖖
Yeah, another SMA video!
Yes, that was Clint Eastwood who as San Francisco Police Inspector Harry Callahan said “A man has got to know his limitations” in one of his Dirty Harry movies.
