Hi, new to the forum looking for help.. I recently inherited my dads 06 lssv, electrical gremlins everywhere. he’s always had an issue with the truck going crazy when hitting a good bump. all the dash lights will come on and the abs light will stay on. After he passed recently I started to drive the truck and found the bump issue to be a missing battery terminal spacer (side Mount terminals) on the 12v battery on the passenger side firewall. replaced that and the truck was going good. one night I was driving in the rain (not sure if it’s related) but the 24v gauge in the truck was swaying. after alittle the truck completely cut out and lost all power. coasted to the side and started tugging battery cables to find the negative on the 12v battery had come loose and was arcing bad, like welding. it melted the terminal and I found the threaded socked for the terminal had come out. anyways I purchased a new battery and now I’m chasing this big short. I’ve even disconnected the 24v side and still getting the big arc when I connect the negative on the 12v batt. this truck has winch preps and I’ve isolated both front and rear so the only think connected to the 12v battery should be the engine. I can’t do a multimeter amp test because it keeps popping my 10a fuse. this truck also has a 3rd battery mounted on the frame right under the passenger door. it’s wired in parallel to the other 12v but he’s had it disconnected for a while and the trucks been running. I’ve also tried disconnecting the 12v alternator and connecting battery and still arcing. sorry if this post is a mess. thanks for any help.
