I have a battery that has bitten the dust because my truck has developed an electrical short in wet weather. I am going to replace the battery and remove the negative terminal anytime I park anytime it has recently rained. Then after a couple days I will test the current flow when off to make sure it is zero to ensure it is sufficiently dry to again leave the battery connected. Clearly this is preferably a short-term solution, though worth doing to avoid killing another battery.

As for the diagnosis so far, I have tried taking out all the fuses that are easily removable and the ammeter was still showing a significant draw (> 200 mA if I remember correctly) with the car and all the accessories off. I am not sure where the short could be if not in one of these circuits, but the other clue is that over the years I have noticed the stereo lapse into some kind of reverb or echo on occasion and thought this could be none other than an electrical infirmity. It hasn't done this for a while but still think it could be a good hint. I am not using any aftermarket amps other than a Kenwood receiver plugged into the usual harness wires, but maybe there is a way of testing these wires for a short or to see if they are part of one of the aforementioned circuits?

Otherwise, I am suspecting something to do with an old starter motor with a rotor that somehow grounds out on the stator when wet or something of this sort .. any suggestions or known issues with this year would be excellent.

Got a leaking windshield dripping onto a relay on your passenger side? First thing I'd do is determine moisture vs water infiltration, put plastic halfway down hood, onto roof and over fenders when it's going to rain again and see if problem goes away. If it does, pull your windshield trim and caulk solid with silicone.
