I have a brand new NISSAN wiring harness setup for a 1970.
I am also planning on a 50 to 80 amp alternator mod.
I am not putting the ampmeter back in, instead a voltmeter will go in the hole.
I'm going to things like brighter lights, fan, fogs, etc and will be putting in
relays to operate said items and any stock items I can think of in the process.
I have read that the stock harness won't handle the bigger alternators.
My question for you electrical engineers and others in the know is:
Factually, what is it about the stock wiring harness that causes its failure
when using a larger alternator? Is it the wire size? I'd rather not build a new
one and I don't want to do a work around.
