I love that we went from mechanical speedos to fully digital ones with stepper motors but the "waving needle" is still a thing and it still signifies a problem. Just a different one.
The biggest cause of problems in cable driven mechanical speedometers was lack of lubrication. I've have one car from 1960 with over 120k on it and the speedometer works perfectly because it was always lubricated routinely.
Correct me if i am wrong... But comparing Shango's power supply board with Bob's, it seems that the caps on Shangos board were mounted 2mm off the board, while on Bob's PSU they were flush with the board. So basically if caps leak on Shango's board the sauce has to run down the legs and if so, pool at the solder joint of the component first. Which we can see evidence of. But on Bob's board with the caps mounted flush the soup gets trapped underneath and spreads all over the bottom, bridging between traces. Thats why I recommended to Bob to mount the replacement caps with a gap off the board.
Those Hondas have a green colored ignition ecc module behind the knee bolster that are notorious for going bad. They induce a voltage drop to the ECU and cause all sorts of problems. Lack of a check engine light bulb check and/or no crank signal pulse is a dead giveaway. Bad capacitors are the cause.
i remember when i repaired a bunch of mitsubischi ecu's those caps had bad leakage and lots of trace gone, funny that people rather paid $350 for a box from the junkyard than repaier the ecu they had thinking that a junkyard box was better than a repaired on in reality it already in bad condition and maybe days from breaking, i did exchange with quality caps and because i didnt want any of them back to fix.
Great video about capacitors in an ECM. I've had two of these to fail on my 93 Dodge Dakota. I've never attempted to fix one before, but the next time I may try what you did here. Cheers! 🍻
Thanks for posting about the problem with the VG91 caps. I have one and use it once or twice week. Like you I only turn it one when I need it. I have the caps on order and hope I have caught then in time. Once you get use to the 91 it is hard to do with out it. I worked in a TV shop back in the late 70s to mid 80s. I had forgot a lot of the issues we ran into back in the day. Not so many bad caps but more semiconductor with the Sony TVs. Video heads and belts for the VCRs. We worked on Zenith but most of that was just replacing modules which was a quick fix if you have the part in the van. Thanks for all of your videos, I watch then all.
Regarding the ECU, perhaps you already know this / have done it but didn't put it in the video or it just wasn't worth repairing, but it might be of help to anyone else trying to repair one of these. Since you know it's throwing an error because it can't read a specific signal, it's at least alive enough to consider being a candidate for repair as the microcontroller is working.. in this case you can try following that pin / pins on the ecu socket back to the microcontroller with a multi meter starting at the socket. Usually the input pins of the microcontroller will have a pullup / pulldown resistor or sometimes a diode / transistor somewhere between the controller and the socket, shorts / bad power surges etc can take them out. I repaired an ECU a few months ago now somebody had re-capped and given up on, it was throwing a no crank signal, following the pickup pins back towards the microntroller I found a surface mount resistor that was a slightly off color, looked ok though certainly not exploded. but no continuity across it, swapped it out and the ecu works again. Had similar success with another ecu a couple of years ago, I can't remember the specific fault but following the suspected faulty pins back i came to a transistor that tested bad, it looked fine but replacing it also revived that ECU too. Worst case is that its the actual microcontroller that has a faulty input pin, which can happen too if you are really unlucky, but its' usually something on the input line that dies first. Oh i'm sure you know too but maybe somebody doesn't but the plague of bad capacitors in the late 90s early 2000s was a big scandal at the time.. if memory serves somebody stole a formula for the electrolyte from either nichicon / rubycon or one of the other big Japanese manufacturers and sold it on the blackmarket to some hong kong / taiwan or chinese capacitor maker. The formula was incorrect and didn't contain the appropriate inhibiter chemicals so you ended up with loads of makers all using this wrong stolen forumla which turned them into mini bombs.. they usually overpressured and blew their tops.
I traced the signal back to that little stand up board next to the bad capacitor. It's just not viable for a high volume shop to spend excessive Time on an old beat down car whose owner has no money. It's triage, You do a quick assessment and then fix those that are Easy to moderate to get back on the road.
LOL now every time the scammers call my phone I wind up calling them back or trying to get ahold of them and I play shango's videos until they hang up just got through wasting 8 minutes of somebody's time hahaha
as I've said in other comments, it's the Quaternary Ammonium Salts/Compound issue. nowadays any caps like that are usually very well sealed and for very specialty situations but are really never seen ever in anything automotive or general purpose. it's usually military spec stuff and places where a specific chemical composition is wanted (which is slightly silly for electrolytics but I can understand it if we're talking precision crap.)
On that VG91, all of those PL series nichicons, albeit not leaking, they had one of its legs tiny bit crusty. Which means you caught them just in time. Those all eventually leak, the leakage is so small at first, there will be just bit of oxidation or discoloration on one of its legs. Over time it starts leaking more and more, when it eventually corrodes the board. Also I do my smell test when desoldering. If there is just a tiny amount of fishy smell, I know the capacitor started to fail.
Might be my eyes playing tricks on me but the negative pins of those sencore caps look like the solder on them was starting to oxidize in that weird way electrolyte causes, You might have caught it just as they were starting to weep
Between you and Banderson I decided to check mine. Like yours, the caps looked fine and tested fine. Although, I did have a slight fishy smell when removing them. I replaced them with 330uf @50V as I did not have any 220uf. Still works. LOL
The electrolyte they used in that era is a ticking time bomb everywhere. I had a new old stock nippon chemicon lxf series in the drawer that started leaking out of nowhere. Real nasty stuff too, stripped the tin from the lead of other capacitors I had in that box. They're replace-on-sight for me. Not even gonna bother testing them. I think elna and few other Japanese brands use the same stuff in their capacitors from that era.
Surface mount caps were a big problem also. Mitsubishi projection TVs would loose video due to bad surface mount caps on the Picture in Picture model. The caps would leak and destroy the copper traces. Most of my customers had no idea they had Picture in Picture ability so I would just install jumpers to bypass the pip module with their permission.
Modern cars with interconnected electronics for literally everything, cheaply made, poorly designed, and rushed out to market with minimal testing - its going to be impossible to keep them on the road after fifteen years. Although I suppose by then both the plastic and lightly build transmission and engine will have already grenaded.
It gives them additional markup and something 'cool' to add in the specs: "all electronic!" and "obstacle detection!" It's why taillight housings for F-150 trucks are now a theft item - they have LIDAR sensors (for obstacle detection) inside which cause them to have a $1200 to $1500 replacement cost (EACH!), instead of the old models that could be had for $120 to $150 (or even less from knockoff manufacturers). The LIDAR systems are really just a substitute for poor or inattentive driving. Also, you can't just NOT replace broken modern taillight housings - the system takes down your radio and HVAC system. They've seriously over-complificated modern cars.
Whoa! Ugly stuff. Buddy had a $1200 tail lamp housing on a '21 Chevy truck. I didn't contemplate any sensors. I just figured it was because it was about a year old at the time.
Yep. Apparently they can leak, maybe it gets cracked or get misaligned, water gets in - then your radio and AC stop working. Huh. What could that be. $1500, plus labor, etc. I'm a hard *ss. I drive a 97 Explorer. The horn is connected (by a wire) to the horn. The wiper-washer motor is connected to the wiper-washer switch. My wife has a 2009 Jetta. All those things pass thru an electronic module. That module connects to the horn, wiper, whatever. That part is $800. When it goes out, one or more of: horn, lights, washer, wiper... stop working. It's just ridiculous. But it explains why a new pickup is now $70,000 and insurance for it is expensive.
Don't you like yellow school buses too? ,,,,,, They're just so cool!! An example of talking about the significance of insignificant things! Can you see her sitting at the table with Putin?,,,,,, God I just got sick to my stomach!! Never mind don't think about that it will "F" up the rest of your day!!
I remember when there was a capacitor plague that effected almost every computer motherboard made. Wikiped says it was from 1999 to 2007. Look it up , it gets interesting. Do you suppose that earlier that a 1999 vehicle ECU should be checked as well?
I replaced many a motherboard cap in the day, I don't miss it. As for pre 1999, definately. For what I dabble in, late 80's ford ecus are always suspect. And I think if you go back about a year in videos you'll find an early 90's ford ecu repair.
I've seen some weird symptoms when ECUs start getting flaky over the years. Right now we have a 2012 Accord 4 cylinder that throws codes every couple of months but still drives okay when the Engine light is on. It usually clears itself after a day.
here in the UK, that era of ECU for in-demand JDM vehicles is absolutely worth repairing, cause the money is there, people want there celica ST185 or S13 silvia to run correctly and are happy to pay.. for an early 90s shitbox thats likely needing welding and god knows what else to put it back on the road when its worth less than 1k. not so much. w.r.t bad caps, i have to say about 70% of compnent level failures in modern vehicles i repair are those little ceramic surface mount caps going open or short, or both, intermittently, for fun.
Honda is cool in such point that if it is good/desirable enough car you can go with hondata ecu. It is "piggybacked" original ecu. The extra stuff inside just alters signals and gives you ability to remap everything i.e. fuel maps, ignition timing etc... i saw it was accord and dont even know if there are desirable body/engine combinations. But it is plug and play, no rewiring needed.
14:16 Chryslers of this era when they lost the ability to find the number #1 TDC, the ECU would just start where ever the engine rested as TDC and through repeated cranking tries the engine would eventually start.
Given that the car fails to start most of the time, and does weird crap with the instrument cluster, I'd argue that error code is erroneous as the ECU is failing to execute code properly and is glitching out.
I have not heard of Corolla E12 (02-07) suffering from this problem. i belelieve mine is made in 2003 and the ecu is burried under the dash, would be difficult to get it out
Word to other UA-camrs- this guy makes the very best electronic videos on the internet. So if he can make a capacitor focused video, and have it be uninteresting, what does this tell you? Stop with the capacitor videos, they are dreadful.
I did experience the passing of time and there was significance in those capacitors .. That speedo was really off on a self induced trip of it's own. The designer probably watched too many Woodstock videos.
Would Trouble Travel from ECU to *Relay,* or visa versa? hey! don't make it harder, i'm Still trying. Caution to what my 'ventures' find. Was *Reading,* [scary in itself] .. there's an avalanche somewhere, just who starts it first, is question. lol Only at OBD1 level, would be nice to grasped more read. 14:14 There's more to that Sensor & ECU than told. haha perhaps even more to scope ability. glad my car's issue [just] fuel. *Thanks,* i'll continue now, fear's gone.
Capacitors high on their legs, flapping in the breeze, ask that man with the leaky ones if he often transported the set in his car. The vibrations in a car and the weight of the cap high above the PCB will have a bad effect on the seals of the connection, and I think that is also partly the case in the automotive branch. Miles and miles of vibration is a bad thing, the motor slopes through all sort of frequencies, so resonance is guaranteed.These caps neet to be bottom flat on the PCB, preferable with three dots of glue not touching the leads.
Excuse my ignorance but what is a "veeyah' or "via"? I'm guessing the main relay problem that these era Hondoos commonly have has been pursued already?
Auto manufacturers should be forced by law to use high end poly and carbon caps in stuff like ECUs and other critical computer controlled components. Using electrolytics in stuff like this is a danger to national infrastructure.
I'm kinda steeling your joke Shango: Don't let leaky corrosive fish caps go to waste! What you want to do after you replace them is carefully open them up and unroll them, get as much goo as you can out of them with a razor blade, put it into a refillable vape pen with a very small syringe or a tiny stainless steel spoon, close it up. Then vape away with a turkey baster (or anything you don't care about) until the heater wire in the vape corrodes through and fails. {DO NOT inhale it directly or let it get on your skin or in or anyone's eyes for God's sake} But I'm sure the smell would be amazing. Then you've done what you can. (I will try this myself eventually... stay safe tho)
That's an awful idea! I told everyone in late 2023 that 2024 was going to be awful and that was my word for the year. That's a funny idea because I can imagine the odor. And is it really any more dangerous than the chemicals in a vape cartridge? I don't know. I don't vape unless I'm forced to buy some other idiot in my proximity.
@@johnnytacokleinschmidt515 Thank you. It's basically the same thing you get when one of those caps overheats and sprays out the white fish-vape. You get an oddly wide range of brand smells also. I'm guessing it's oily fish sauce with industrial preservatives. The one I hate the most would be the 'mint-less menthol fish' There are 80's caps that actually smell like that, nearly made me drink hot sauce to get it out of my sinuses when I de-soldered that big bastard. I saved it in case no one believes that smell is even possible, which it shouldn't be but is.

The insignificant passage of time for those capacitors, is significant to those capacitors passage of time! So let me Recap!

The late great Hannibal Lecter (Who could, still be alive), ate the brains out of it.
The capacitors have been unburdened by what has been.

Regarding the ECU, perhaps you already know this / have done it but didn't put it in the video or it just wasn't worth repairing, but it might be of help to anyone else trying to repair one of these.
Since you know it's throwing an error because it can't read a specific signal, it's at least alive enough to consider being a candidate for repair as the microcontroller is working.. in this case you can try following that pin / pins on the ecu socket back to the microcontroller with a multi meter starting at the socket.
Usually the input pins of the microcontroller will have a pullup / pulldown resistor or sometimes a diode / transistor somewhere between the controller and the socket, shorts / bad power surges etc can take them out.
I repaired an ECU a few months ago now somebody had re-capped and given up on, it was throwing a no crank signal, following the pickup pins back towards the microntroller I found a surface mount resistor that was a slightly off color, looked ok though certainly not exploded. but no continuity across it, swapped it out and the ecu works again.

That needle is as nervous as a long tail cat in a room full of rocking chairs!
as I've said in other comments, it's the Quaternary Ammonium Salts/Compound issue. nowadays any caps like that are usually very well sealed and for very specialty situations but are really never seen ever in anything automotive or general purpose. it's usually military spec stuff and places where a specific chemical composition is wanted (which is slightly silly for electrolytics but I can understand it if we're talking precision crap.)
Good troubleshooting
This insignificance of the significance is in itself significant.

Do these leaky capacitors affect 1990s GM truck computers as well?
in my experience the GM ECU's of that era were all surface mount components.

My 1993 Fiat Tempra had ALL the capacitors leaking on the alarm module and ECU
I'd be looking in that Sencore again in five years or so, Kemets aren't the worst but they will fail more quickly than was in there originally.
maybe it'll fail up, not down, so it won't even matte, it won't destroy the pcb.
maybe we'll be dead by then, etc.
For some reason all the caps I bought in the eighties are still good.
Liked the detailed analysis ....vary interesting
Bad caps. It's almost always bad caps! Back to the 1990s and with a little heat and time they leak onto the circuit boards.
Electrolytics turning to resistors is what killed my eMac.

I work at a place where this stuff is common, 1KZ ECU’s are really bad sometimes

capacitors are significant
Love your shtick man, great humor !
The cost of either a new , refurbished or aftermarket ECU is significant . There could be lots of unknowns not known that need to be known .
Kamala Harris and Donald Rumsfeld. Very nice tip of the cap!
The Honda accord and civic are very notorious in hard starting, because of distributor backup coil module problems .

The significance of significant passage of time, is that the ECU is seeing the significant passage of time.
For this ECU the passage of time is now insignificant.
Preventative maintenance like pulling wisdom teeth
I noticed that when those caps start puking, they smell like the tuna schooner.
Smelling the piers of Coronado, California in the mid-70's. I used to love that smell as a kid. The old man ran a fishing boat off Coronado island.
I would have used 105 °C capacitors instead of 85° C caps. Sencore probably used 105 for a reason.

Jeez dude...take it easy on what your scraping!
no one is talking about the "significance" of this video gosh it's going to be a tough 4 more years
Summary: That politician has nothing significant to say, so they are insignificant.
The ending of this video was very significant!
Significant in the passing of time to capacitors and we should explore the insignificant meaning of that significance.
Svenghouli movie: CAPACITORS ATTACKING BOARDS
Sven is awesome
I did experience the passing of time and there was significance in those capacitors .. That speedo was really off on a self induced trip of it's own. The designer probably watched too many Woodstock videos.
The significance is that now there is a real opponent in the race.
Thanks God! Nobody deserves the orange guy anymore.
What do you think having her for president will do to energy prices?
Certainly you MUST be trolling.
@shango066 Energy will go sky high obviously. She's definitely not an engineer or a business negotiations expert 😂
@@shango066 Nothing. She's the same we have today. Unless you are believing in paid social media conspiracy theories.
The word for today must be "significance".
Would Trouble Travel from ECU to *Relay,* or visa versa?
hey! don't make it harder, i'm Still trying. Caution to what my 'ventures' find. Was *Reading,* [scary in itself] .. there's an avalanche somewhere, just who starts it first, is question. lol
Only at OBD1 level, would be nice to grasped more read. 14:14 There's more to that Sensor & ECU than told. haha perhaps even more to scope ability.
glad my car's issue [just] fuel. *Thanks,* i'll continue now, fear's gone.
Capacitors high on their legs, flapping in the breeze, ask that man with the leaky ones if he often transported the set in his car. The vibrations in a car and the weight of the cap high above the PCB will have a bad effect on the seals of the connection, and I think that is also partly the case in the automotive branch. Miles and miles of vibration is a bad thing, the motor slopes through all sort of frequencies, so resonance is guaranteed.These caps neet to be bottom flat on the PCB, preferable with three dots of glue not touching the leads.
its probably the cluster board
Excuse my ignorance but what is a "veeyah' or "via"? I'm guessing the main relay problem that these era Hondoos commonly have has been pursued already?
It's a connection between sides of the board.
Ahh. Thanks.
Auto manufacturers should be forced by law to use high end poly and carbon caps in stuff like ECUs and other critical computer controlled components. Using electrolytics in stuff like this is a danger to national infrastructure.
Doesn't help cars live in non climate controlled, wet, dry, hot, cold, and vibrating conditions. It accelerates the death of the caps.
Kamala is horrid.
She is scary.
I need to find me a spare ECU for my car and then recap it.
You can smell the methlamine...
Its not uncommon for old caps to outgass before leaking leading to local corrosion
My vote has become less and less significant with the passage of time.
SHANGO!!! WUZZZZZZZZZZZ UP !!!!!!!
Probably shouldn't try to start it going 88 mph 12:40
If you don't listen to people then I guess maybe signing out is for you
I'm kinda steeling your joke Shango: Don't let leaky corrosive fish caps go to waste! What you want to do after you replace them is carefully open them up and unroll them, get as much goo as you can out of them with a razor blade, put it into a refillable vape pen with a very small syringe or a tiny stainless steel spoon, close it up. Then vape away with a turkey baster (or anything you don't care about) until the heater wire in the vape corrodes through and fails. {DO NOT inhale it directly or let it get on your skin or in or anyone's eyes for God's sake} But I'm sure the smell would be amazing. Then you've done what you can. (I will try this myself eventually... stay safe tho)
That's an awful idea! I told everyone in late 2023 that 2024 was going to be awful and that was my word for the year.
That's a funny idea because I can imagine the odor. And is it really any more dangerous than the chemicals in a vape cartridge? I don't know. I don't vape unless I'm forced to buy some other idiot in my proximity.
@@johnnytacokleinschmidt515 Thank you.
It's basically the same thing you get when one of those caps overheats and sprays out the white fish-vape. You get an oddly wide range of brand smells also. I'm guessing it's oily fish sauce with industrial preservatives. The one I hate the most would be the 'mint-less menthol fish' There are 80's caps that actually smell like that, nearly made me drink hot sauce to get it out of my sinuses when I de-soldered that big bastard. I saved it in case no one believes that smell is even possible, which it shouldn't be but is.
Love the speedo . Lmao
Scrambled word salad for dinner.
bro you know = caps , + ECU + DISHWASHER + WASHING MACHINE + anything 2000+ , Rubicon better , some nichicon caps there list of bad caps wiki, check out tech tangents wiki or bad caps wiki..
At what point? Right after you realize her opponent is 10x worse.
