So I've been doing the frantic rush to get the pig together for a week long road trip, next week. A current problem that has been occuring is an electrical short. It doesn't help that the wiring diagrams for my vehicle do not match any color coding on the actual vehicle. This is on an early fj55. The 5amp fuse on the fuse block keeps blowing. You can idle the truck all day long, but once you drive it for 20 minutes, the fuse blows. As long as the engine is hot, it will constantly blow fuses when you replace them. I know that sounds wierd and is probably a coincidence, but that is what is happening. The circuit in question runs the 4wd indicator light, the backup lights, the fuel gauge, temp gauge, and oil pressure gauge. It may run more, but I'm not sure. My gauges are important to me on road trips. I recently had this problem and was curious about the fuel level left on a run and replaced the dead 5A fuse with a 10A. It blew withing seconds, making me think I had a direct short. However, I'd think a direct short would blow out the fuse right away all of the time. I've unraveled the first part of the wiring harness, it looked fine. The wiring harness to the rear also got pulled out and appears to be in good shape. I looked around under the dash, but couldn't inspect that well without dismanteling the dash. The only thing I know it isn't is the gauge cluster, since it blows without it connected. Anyone have any suggestions of where to start looking and how to troubleshoot a problem like this? I don't have much time to wrench before our trip, so pulling the entire harness out is out of the question. If worst comes to worst, I'll just wire in a new circuit temporarily.
