Reply to all.
I'm no expert, that's why I tried to explain as best I could. I didn't know whether that leg connected to anything or not, is why I started scraping the laminate. I tried to post a picture that shows exactly what I was talking about, but for some reason it does not show in my post. I was not going to assume it connected to either path because if I reconnected with some form of solder trace or jumper wire, it may very well blow the thing again, or other things would stop working. AND it would be 50 50 at best because there are paths at both ends. So I'm doing the best I can at figuring out a circuit board with nothing to go by. I do know there were 8 i.c's (fets?) that were toast because they were causing the initial issue, along with the 8 diodes beside them. After replacing those, it half way worked again. I had a local electronic guy look it over and he tested those, and suggested I replace them. That much $ per hour to have someone try to diagnose something without schematics was not an option for me, or him from what I could tell by looking at his face when I handed it to him. I could have bought a new truck and would of been cheaper.
This is a module that controls the air ride on my truck. Yes, I have no other way than a shotgun approach. After replacing the fets and diodes and finding it still was bad, I noticed when looking through the microscope that 1 of the i.c's had burnt the plastic base on 2 connectors (1 on each side of it) and this i.c is the one I was replacing when the pad popped off. I figured this one was bad for sure if it put out that much heat to melt plastic a quarter inch away and only measuring less than a quarter inch itself.
I assumed that pad went nowhere, but need to be sure. If it does, then I'm lost because I can't test or see where it would go, other than copying the path of the other 2 identical i.c's but that's also not a good idea. Each one has a resistor array, and 16 connections going different ways.
I have no idea what caused the problem in the first place. The truck was at a body shop getting panels fit and painted. There was a leak in 1 of the air lines, and the shop had to keep airing up to move the truck around. No engine, just cab and frame with the airride installed. I suspect they killed the battery then tried to jump it. I also assume they jumped backwards, or even used a 110vac transformer for their electric fence to jump it. They won't admit to any of it. But it worked just fine when dropped off, and blown when picked up. And this particular module is obsolete.
Thank you guys for replying. I'm a bit of a long winded pitbull, and just can't stop trying to get this thing going.
Again, how do I get a picture posted here?
