96 XJ, 4.0, Auto, power everything, plus aftermarket stereo & alarm stuff by a previous owner.
So, I had the bad headlight switch problem, blowing the fuse and cutting out my running & dash lights. I finally got around to replacing the headlight switch, taking apart the dash and remove the gauge cluster to do so. I thought, there must be a short somewhere to make this problem show up, so I found this loose end from the alarm system. I never used the alarm, not sure the guy I bought it from did, either. I removed a fuse on that lead (I traced it, it really is from the old alarm), and it was full of corrosion, as was the socket, and left the ends taped and securely not touching anything. I put everything back together, and my lights all work the way they're supposed to.
One thing odd, I have no fuse in the fuse block for the power windows (I think that's the position), just a wire coming straight out of the fuse block into the interior wiring harness. I had thought this wire was for the alarm, and left it unplugged (since I don't use the alarm), but then my windows didn't work until I plugged it back in.
But then, when I dropped it off for inspection, the shop said they found it with a dead battery. And when I took it home, a funny thing happened. I turned the heater on, from the off position. When I did that, all the gauges went down to zero and right back up again. The generator light came on. I tried it a couple more times, and got the same result. The heat works, the fan blows. When I got home, the gen light was off. Before I shut it off, I had my wife turn the heater on, while I listened under the hood. There is a strong single clicking sound from the main power distribution panel when the heater (or vent position, basically anything outside of "off") is turned on.
Any ideas? I suppose I'll find a dead battery tomorrow. If anybody has some good electrical knowledge about these beasts and can give me pointers, I'd appreciate it. To start with, I'd like a picture of a fuse block that's factory original. Mine's been modified for this alarm and who knows what else.
Thanks!
