Wiring diagrams and electrical repairs are incredibly intimidating to me. But watching you troubleshoot by using a diagram not only gives me the gusto to think I can dive in and tackle something like this but it’s also really educational and informative. Thanks Ray.

In my experience as an electronic engineer, is that many over heating situations at a terminal is due to poor connection. The make and break of contact cause arcing and a lot of heat, especially if its a high amp circuit. That arcing alone can melt things without any components in the circuit being defective.

Totally agree with you on this. Totally poor design. I know they have to put the battery on the opposite side where the driver sits, this is why German car makers put them in the boot. Helps handling and safer, away from prying fingers and heat. Also helps to have rubber matting. I haven't finished watching but my standard action with some manufacturers was to make a rubber mount mat and in other time create a rubber coated box with ventilation to isolate the battery. When i did stealth high performance audio installation way back in the 90's before manufacturer installed dash radios were common, used to use 2 to 6 5000kva caps for high draw use and a seperate high current fuse box. I despised aftermarket installers that just lumped extra connection to the terminals and now I see the US manufacturing cheapskates doin it 🤦‍♀️🤣

@mariusd5913 Жыл бұрын

@@dvvaughn564 to your point, one may consider that the issue is on the cable terminal side which did not get replaced or a nut that does not lock properly. One can only speculate. But poor contact around the heated area is a high probability either way. I don't recall him pulling the insulation back to check if all of the cable going into the terminal is still in a good condition, so the issue may still be there, who knows.

@mariusd5913 Жыл бұрын

Think about it this way, what kind of current will heat up those bolts and bus bars but not heat the cable? when your contact has like twice the metal but that's where the heat is, then it's resistance or arcing forming at or near the contact and probably not an over current condition.

Eric O had one of these power steering problems the other day that the dealership was going to charge thousands for. It turned out to be the braided grounding strap on the passenger side between the frame and the firewall. The corrosion was interrupting the electron flow after being inundated with salt. The fix was a $14 insulated battery lead.

The skill set to tackle accurate trouble shooting takes experience and proper scanners which cost to of money to acquire and you would still have to pay for updates for the scanning tools and those are not cheap.

I was going to say the same thing. Many years ago, I was called to a generator that had tripped a breaker. The breaker was a 1500A 415V 3-phase breaker. It was a BIG generator. The draw from the generator was around 900 amps/phase. The cables had very large solder-type lugs to terminate them to the breaker. One of the lugs had dumped all its solder and dropped a phase. (LOTS of overloads to reset on motors). I took the breaker apart and found that the resistance from line to load on the offending phase was 1 ohm. The others were something like 0.08 ohms. I pulled the breaker apart and resurfaced the contacts and put it all back together. Resoldering the lug was a pain in the rear end. The problem wasn't an overload. It was a tiny bit of resistance that shut down a factory until I fixed it.

As a dealership tech, I usually shy away from anything involving issues with an intoxalock or removed intoxalock system. If you’re not careful, you can get yourself into a lot of legal trouble especially if they aren’t supposed to have it out of the vehicle. Typically that system has to be worked on by a specific place and if this happened after they had it removed, I’m tempted to think it was removed illegally. I wouldn’t think that the people certified to put those in and take them out would mess it up this poorly to where it’s borderline electrical fire…

Ohm's law does not apply to HRCs (high resistance connections) because they are basically using air space or in some cases semi conductive corrosion to bridge the connection and that is where the heat is coming from due to arcing. This is seen a lot in high voltage applications and even in residential connections. Connections have to be tight or they will get hot.

Just in case it does it again, I would have put some sort of heat insulator (maybe exhaust wrap type stuff) between the terminal and the battery to at least save the battery from damage if it were to happen again. And as someone else mentioned, SMA had a corroded ground strap to the frame that affected the power steering. I would be suspecting the power steering if it's drawing too many amps (although you'd think the fuse would blow). But to have it happen twice, I would not let it go until the CAUSE of the heat is actually found.

"I would have expected the 175A fuse to open if there was enough draw to melt..." The amperage may be below what was needed for the fuse to blow, but for some reason is drawing continuously, when it should only draw for a short time. The continuous, high amperage draw, but below the fuse rating, could create enough heat to melt the plastic. This may not be the issue, I'll now finish the video. However, be aware that this could happen. I've seen in when folks plug a small space heater into a surge protector. The amperage is small enough to not trip the breaker in the surge protector, but the surge protector is not designed for the high, continuous draw of a space heater and the surge protector will melt. He's correct, a loose connection could cause the heat build-up. To check the alternator for something weird, the vehicle needs to be run through several scenarios, such as driving with lights on, AC on with blower on high, etc., then start turning things on and off to see if the alternator responds properly.

I=E/R as they say, not just a good idea, its the law.

Great fix, love your videos.

@spelunkerd Жыл бұрын

Yep. The voltage drop across a loose connection can be easy to measure, and similarly you can measure current with an inductive ammeter without touching the connection. The power loss at that point is simply i*V. Those Joules have to go somewhere, they end up as heat, which increases resistance, which increases power loss, spiraling out of control. Worse yet, the downstream device often doesn't do well with reduced downstream voltage, meaning it stays on for longer, increasing energy demand, and maybe even killing downstream connectors and devices. Because current may actually be reduced, no fuse will help that.

Check the lugs. That wrapped cable with the blue tape on it looked very suspicious and should be inspected. Turn on all of the big loads and check again with the thermal cam. Testing these circuits with a multimeter is tricky. It might blow up your meter's fuse. Use some headlight bulbs instead, wired in parallel and use that as an amp meter. If they light up bright, the circuit is drawing lots of current or is shorted.

Maybe next time use the ohms setting rather than the continuity setting to check alternator wire? ATM there won’t be much current flow on the alt wire with a fully charged battery, but if the battery is low you could have over 50 amps in the circuit, builds up heat quickly if there is some resistance.

@TrailRider1200 Жыл бұрын

"Check for continuity" = measure ohms, and he clearly has the meter set to ohms. He is using the multimeter to determine whether the cable in question is going to where he thinks it is, by using the resistance of the wire (If meter reads OL, he is not completing the circuit i.e. not the same wire)

@slincolne Жыл бұрын

Bad/corroded/dirty connection is likely the problem. If the connections were good, their resistance would be close to zero ohms and the power drop (and associated heat dissipation) would be close to zero. I would not rule out the possibility that someone had done some earlier maintenance (possibly on another battery block you haven't seen) and did not clean and tighten everything correctly when reassembling.

I would assume the high-current draw that melted the terminal block and battery would be related to the electrical power steering, it is the only thing I can think of that could draw a ton of power like that and not blow a fuse. Could have been a loose connection, but for that to happen twice on two separate terminal blocks seems unlikely _unless_ the wire itself or the connector on the wire is damaged as well causing a higher than normal resistance through the wire. That would mean it is the wire or connector on the wire that is causing the excessive heat that ruined the terminal block and you would only see the heat while the steering wheel is being turned back and forth... Eric O. did a similar one of these recently and it was found to be a grounding issue, sort of the opposite problem. A high-current ground wire to the frame down by the wheel well was corroded and crusty causing a lot of strange issues when the electrical power steering was being driven hard. A hard turn to the left or right would draw a lot of current, what Eric O discovered was a voltage drop whenever the power steering was drawing lots of current.

@jimmeade2976 Жыл бұрын

I agree with Marius D, and am also an EE. As Ray says, it's pure speculation what happened. My guess is that the interlock was installed on the burned up terminal and wasn't fully tightened, which caused the first module to melt due to arcing on a loose terminal. When the interlock was removed, that was noticed and the module replaced, but the terminal again was not fully tightened, resulting in the 2nd melting, plus the battery melting. The other terminal melting is probably just coincidence ... it's possible that was overloaded because current found it easier to go that way to different modules than through the loose melted terminal. Electrons will follow the least path of resistance.

I will admit, the circumstances behind this fault are somewhat mysterious.

Knowing that Chevy's also have a HISTORY of bad grounds, I'd be checking those braided ground straps -- especially if the vehicle has been anywhere near the rust belt.
