Upgrading the electrical in my '72
Well, since I've got the car torn apart right now putting the engine in, I was going to address a minor upgrade of the electrical system and wanted to get opinions to see if I should/should not.
The way the '72 is wired from the factory is that there is a positive battery cable going from the battery to the starter. From the same starter post, there is a fusible link connected to a 10 gauge wire which goes to the horn relay. On the alternator, there is a 10 gauge wire that goes from the charging post to the horn relay.
The current stock charging circuit goes alternator->horn relay->battery (via starter 10 gauge & fusible link to large battery cable) and stock power circuit goes battery->horn relay (via starter 10 gauge & fusible link to larger battery cable.)
The fusible link at the starter protects the car from a short and will blow the fusible link at the starter and completely cut off the battery from the rest of the car.
Since I've added a larger alternator and a few other goodies, I wanted to update those 10 gauge wires to 8 gauge wires.
I also was considering moving the fusible link and wire connected to the horn relay from the starter stud up to a stud on the positive battery. You get the exact same wiring flow (alternator->horn relay->battery for charging, battery->horn relay for power), except the fusible link is now at the battery instead of at the starter and is much more accessible should there be an issue, and also I can keep yet another wire away from the exhaust.
Any opinions on that (yay or nay?)
