1989 5.0 batt drain

4.5 amp draw with key off. Any recommendations? Jim 252 455 6070 Drag Racer

Pull the fuses one at a time till the draw goes away and that will be the circuit to look at.
BTW, it helps to tell us what you are working on.

Did that first! Now checking all diagrams for what is hot all time. Any help is appreciated.

I believe the 'hot all the time' wires are on the positive side of the solenoid.

With an amp draw that large, I'd be thinking a diode is possibly burnt out in the alternator.

Windows, door locks, brake lights (running lights run through the mfs switch) and emergency flashers are hot all the time.
The above suggestion is also a possibility.

i would start by pulling fuses 0ne at a time, see if you could find it that way, if not look at the wiring diagram, see what is hot all the time. 4.5 is a large draw.

I had this problem when I first got my car. Unplug the alternator and test.
