Subject: Re: Need some electrical smarts. by hcbph on 2016/4/9 17:54:28 I still have to reassemble a couple of things, but I think I found the culprit circuit. Here's what I did to track it down. I started pulling the wires off that junction between the battery and firewall one at a time. I jumpered from the engine to each wire to see if there was a circuit or not via an OHM meter, one proved to be completing a circuit (2 wires off a common eyelet). Wire looked to go into the firewall and maybe to the cooling fans but wasn't sure, so went back to the cab to check further. I have the car parked so the passenger door won't open fully so the fuse panel is hard to see and there's no diagram on the back side of the fusebox cover. I found a diagram online to fill in the holes in what went where. What I thought were relays turned out to be circuit breakers, and the 4th one down from the top is for the power door locks and electric seat. I hadn't pulled the breakers before, only the fuses and when I pulled that one for the locks and seats the short immediately showed gone. I used jumper cables to connect the cables in the car to the battery (everything is out now) and I no longer show voltage or amps coming off the engine. I also doublechecked with the ohm meter, looks good. Logically the locks are hot all the time and it's very possible the short is in the doors or the wiring to the doors. The seat is already set for me and I've only used the power locks when the wife was going along. I can live without them for now. I'm planning on changing the weather stripping on the doors later and I'll look into them further at that time. Once I have it back together, I'll recheck and confirm whether it's all good or not. Got my finger crossed. |
