Hi..
Problem is that battery is draining overnight. It is drawing 3.95 amps with key out.
I found that the battery junction box under hood, F1.18 ...60amp fuse is close to the problem.
This is the only fuse under hood or under dash that stops the current draw when pulled.
Looking on Alldata diagrams, I see that the "DG" wire is coming through the firewall and feeding the under dash fuse box.
I will look at this tomorrow to confirm color code. Is that dark green?
I also see that cigarette lighter is on the circuit.
Can anyone point me to what the next step would be?
Thanks in advance.

 

I believe you have a couple of choices.
One would be to pull the fuses one at a time for anything that is always hot so to speak. When the current drops to about .05 amps (or 50 milliamps) that could be the circuit involved,
The other consideration would be to trace the diagram and note all the circuits supplied by that fuse. You could either disconnect each item in the circuit until the reading drops or start with voltage drop testing and the highest difference may lead you to the cause.
If you have a partial short in the wiring and not a component the voltage drop test will lead you to the area.

Has this vehicle ever had the windshield replaced ?

 

I just checked something else, I checked for AC voltage across the battery posts and am getting around 30 volts. Will check further, but I might have a bad diode in the alternator which is on the circuit. Still shows proper dc charging voltages.

 

If you take the alt out of the circuit that should be enough to confirm your suspicions.
