You "fixed" it I'm going with the AC switch Check your wiring, what circuit you wired into, etc. If you don't find anything start looking at the wiring close to where you were physically working. You've got power bleeding off one wire to another somewhere probably. Either in fixing you made a mistake in wiring or pulled, crossed, broke, cut, or shorted other wiring.

Finally there is the possibility they are unrelated but figure that as a last resort.

So you jumped it and when you pulled the neg jumper it quit?

How many volts does the battery show post to post without the engine running?

Now how many volts does the battery show metering between the positive post and a good ground? Try putting the neg meter lead in several places like on the fender, at the radiator and somewhere on the block. All should be above 12v and close, like within 1 volt. Make sure your lead is on bare metal. If it's low or non-existant scratch through any paint to make sure you have a good connection.

Disco the jumper or disco the neg cable batt to truck? IE; never disco the batt while the engine is running.
