Another ammeter bypass question
The problem with fuse links is there is often little or no documentation about their amp ratings similar to a fuse/ breaker. I would not fuse the red black up in the dash, you want the fuse close to the source, the alternator and the battery, and BIG on the battery. Make sure you inspect/ fix the bulkhead feedthrough stuff.
Another way around this is to get the bulkhead in good shape, connect the ammeter wires, leave the old wire in place, and run a new, larger wire from alternator to battery with a fuse/ link/ etc in that line also.
I think Crackedback came up with this, and the only issue I have is properly fusing it. You could also use the big fuses like used in the stereo world "max fuse" is one buzz word
