My 93's electrics stay on after the car is turned off. I have to disconnect the battery to turn it off. My basic question is how do I hunt down this problem? I don't know how to figure out what is causing this problem. I need some basic advice on how to trouble shoot this. Thanks!

 

Is it ALL electrics, or just specific ones?

I know the overhead/map, glove box, ignition, rear hatch, and keyhole lights are all on the same circuit. Also in that circuit is CPU #2. I believe that CPU is responsible for shutting off the lights after a delay, and also turning on the keyhole lights when you pull up on the door handle.

The wiring schematics will show you which electronics are grouped together.

I'm currently having an issue where all of the interior lights are intermittent for me. Sometimes they come on, sometimes they don't. My grounds are all good, so I'm about to swap CPU#2 out with another FD that I have to see if that resolves it.
