Hey there,
I have a 97 explorer 5.0 limited edition. I have an electrical problem I'm trying to narrow down. Starting about 2 weeks ago, the battery has been going completely dead over night. The battery was replaced late 2008 and the alternator was replaced (wasn't charging) a couple months ago.
I performed a parasitic draw test and I was getting a 0.56amp draw with everything off. I started pulling fuses and found out the JBL audio circuit was drawing 0.1amps (30amp mini fuse in the power distribution box under hood). My stock JBL subwoofer hasn't worked in about a year so something could be going on there. I was pulling more fuses and found the remaining 0.4amp draw was coming from fuse 25 in instrument panel which powers speedometer and GEM system.
This is where I'm stuck. I don't know what GEM really is or what all it controls. All I know is that it controls various modules. I noticed with that fuse removed, my wipers, power windows, and dome lights don't work. I'm sure there are other things GEM controls if I kept trying stuff.
Any advice on how I can narrow down with component is drawing power? It would be a little easier if I knew all of what GEM controls.
