92 Explorer will not hold charge
I have a 92 Explorer pushrod 4.0 that runs the battery down in a matter of hours. I went through all the tests in the Haynes manual and cannot isolate the drain on the battery. I have checked the battery, the alternator, and voltage regulator, and they all seem to test ok. I guess my next step is to disconnect all the components that show to be hot all the time in the wiring diagram, i.e. ingition switch, power distribution box, etc. Any spark chasers out there, can you help me? Thank you...

I think I figured out my problem...it was a stuck fuel pump relay and not a short. A quick way to tell is to disconnect the positive battery cable and then reconnect. If you hear a click and the pump runs for a couple of seconds with the key off, you might have the same problem. Either replace the relay or disconnect and reconnect the relay to reset it.
