AH, Moparts strikes again! It happens with nearly every question concerning an electrical problem.
We have competing experts saying the other guy is wrong and his testing methods won't work, but mine will.
Is there any wonder why non-electrical people are confused about electrical problems? I've done a lot of automotive electrical repairs, but you guys can confuse me.
The experts argue with each other on how its suppose to be tested and figured out, and all the guy wants to to solve his problem. Who is he suppose to believe?
How about, if YOU have actually SOLVED the particular problem on a similar car the OP has, write a step by step process. If you personally have not solved the problem, don't post. This should not be a location to test theory.
Disconnect negative terminal from battery. Connect a test light, ammeter, whatever, to indicate current flowing from - post to - terminal. Amperage or lights on indicates current flowing through something. Knowing how much amperage is flowing can be a clue as to what is on. Allow it to sit for a minute to verify that the draw doesn't disappear due to some timed circuit. A small light bulb or relay stuck maybe 1/4 to 1/2 amp. Other items staying energized will pull more.
Isolate and disconnect circuits until the draw goes away. Once you isolate the culprit, hook the other stuff back up to verify nothing else is going on.
