Hey guys, I need a hand with the wiring on my 240Z. Recently I have been trying to get the wiring working properly. The whole system is very shaky and annoying due to the 36 year old wiring. I recently got the head lights half way working, but have begun blowing the fuse marked IGN which also happens to run some of the gauges and four way flashers, I believe.
Anyways, I don't know where the wires coming off of the fuse block go exactly, and I need a hand figuring it out. I've already tried disconnecting my gauges (oil pressure, water temp, fuel) and emergency flashers. I think this fuse also runs the voltage regulator, but I have that jumpered off because I am using a ZX alternator (could this be causing the issue? tried with voltage regulator and that doesn't work either!)
Anyways, the wires coming off of the fuse block are solid green and black with a white stripe.
Here are some pictures of the black with white wire that I'm dealing with. I only took pictures of it because the green wire is nearly impossible to trace due to the amount of green wires in these cars and also because the black with white wire seems to be severely melted due to the fuse failing improperly and continuing to operate after it should not have:
Large part of wiring harness underneath far passenger side of dash.
Top of that part of the harness.
Melted up fuse block.
Wire coming directly from fuse block. It's hard to tell in the picture but it is badly melted, and there is slack all around the inner wire.
Same melted wire coming out of the same connector set.
Picture of underneath side of melted fuse block and both wires circled.
I appreciate any help that you guys may offer. Thanks in advance!
