Hey everyone. My name is Angel and im new here. Ive looked everywhere for info on fixing my electrical problem on my suburban but have been stumped. I went to go and loosen the positive terminal and touched the body of the car on accident. Since then my suburban will only intermittently start and I have 0 functions inside the vehicle. Windows dont work, door locks seem to short out with the ignition off, activating my rear tails whenever i push them and not actually locking or unlocking, rearview mirror compass doesnt come on, no exterior or interior lights work including cluster, no blower functions. I ordered a BCM assuming it was that but no luck. Fuses have all been checked and none seem to be bad. Ive heard of a mega fuse or fusible link that could also be the culprit but cant find any information about it online for my specific vehicle. Im starting a new job this coming week and really need to have a vehicle. It was recently stolen as well and i replaced the starter and ignition but it was fine and drivable before I made that dumb mistake. Thanks for looking.

 

was the engine running when that happened?

measure resistance between the alternator positive stud and battery positive terminal.
