I went out and started the truck last night and let it run for about 10 minutes to warm it up and then I shut it off. Today when I got home from school I was going to take a ride in it and when I turned the key nothing happened. No gas gauge, ammeter didn't move, and the 12v converter didn't come on. This has happened before so I tried jiggling the wires. Nothing. Then I tried tapping the back of the ammeter and the key switch. Still nothing. Next on the list was to take the wires off the back of the ammeter and try to test them, but the nuts had seized on the threads(strange, since they were off in the last two years). Ended up having to take the whole thing out of the dash and grind the studs off. Now, my question is: Is it possible that the ammeter just went out or that the wires in front of the switch shorted? I ran a jumper from the batter to the switch and everything worked, so it has to be in these two locations. I'll have to replace the wiring anyway, but if there's anyway to know that the ammeter quit working it would be nice to know.
