So I was driving my truck a few days ago and the dreaded "gauges, windows, door locks, heater/AC, everything" went dead. This seems to be fairly common based on the multiple previous threads. Here are just a few: 1, 2, 3 Just like the others, my GAUGE fuse was blown. OK, turn the truck off, replace the fuse, turn the key to start and the fuse pops immediately. So what I know from that is that there is a ground fault in one of the many downstream circuits that rely upon the GAUGE fuse for protection.
I've never encountered this problem before and I can't seem to find a step-by-step on how to debug this condition and fix it. I thought this would be a good chance to figure it out with all of your help and document the shortest and easiest path to victory. If you know of such a step-by-step, please reply and give a link. Otherwise, grab some popcorn and come along with me on this one.
BTW, my truck is a 1996 LX450 with no significant modifications to the wiring except for a two pairs of Baja Designs lamps on the front bumper. They are properly wired with their own fuses, relays and push button switches to the left of the steering column. So my truck is stock as far as wiring goes.
