alternator wires
Ok, i'm all ears. What should the recommendation be for a maxifuse in this alternator circuit? Is there some sort of chart online i can use to calculate this.
If i am to remove the stock fusible link out of the body harness. It is a 16 GA link attached to a 12 GA red going back to the battery. I would assume Maxifuse here as well? This is the batt hot that feeds the body harness. I dewired my ammeter and tied the 2 leads together.
If you have a 50 amp alternator , I would use a 60 amp MEGA fuse to protect .Your 8 gauge wiring will support a 60 amp circuit.
I am personally re-wiring a mopar project car and I am using a marine style sub-panel to protect the fuse panels (two), extra relays , and the feed into the ignition switch. A separate 175 amp mega fuse with 4 gauge wiring to the alternator ( It is a 165 amp alternator for Hemi engine) .I am also using relays everywhere I can to take the load off the ignition switch and Head light switch.
Every project is going to be different, I would take an amperage reading with everything running and see how many amps are going through the wire you want to protect.
You want the fuse to be a little higher than that , but not fusing more than the wire gauge can handle.
A pro-touring car with EFI, power windows, A/C , sound system, electrical fans, high output headlamps etc. is going to need a lot more than the factory ever needed.
It's like house wiring you run a 15 amp circuit breaker with 14 gauge wire , if you are going to run more amps in that circuit you will step up to 12 gauge and 20 amp breaker and so forth.
If you are pulling more amps than a 12 gauge wire can handle , then you need to feed the higher draw circuits with a separate relay to lower the amperage to an acceptable level.
