Electrical issues - Mainly alternator based

[bry593]

I use 30 amp midi fuses instead of fusible links. I've got two of these fuse holders screwed to my passenger fender and then a 6 gauge wire from the positive battery cable to the fuse holders. The fuse holders are bussed across the battery side using a piece of 3/8" copper tubing I smashed flat and then drilled.

One of the fuse holders runs the normal GM circuits. The second runs my radio, amplifier and trailer light / power circuits.

I actually had one burn out not too long. The Chinese tachometer decided to fry out and it pulled enough amps to fry the 30amp midi.
Note that GM did not put a fuse on the tachometer power wire (pink), so I put a 5 amp AGC fuse inline for added protection.

For battery cables, I used late model Chevy cables. They are 2 gauge with 6 gauge secondaries. Can't remember what they came from. Maybe a Tahoe or something like that.
