Alternaor

[MARKDTN]

You do want to be careful adding a big alternator with factory ammeter wiring. I think you are being advised to do away with the factory red wire that goes to the hot post on the alternator and add a larger wire direct from battery to alternator hot post. To me I would step back and re-evaluate your big picture plan. 1- one wire alternators are not the best choice for constantly changing loads. They work well for machinery that has few loads and just starts and runs a while. I do not consider them to be a good choice for a road vehicle. 2-bypassing the ammeter in a 67-72 needs to be done completely and correctly or you may still have high current in a low current wire. 3-CS130 alternators are inferior to CS144 but share wiring. Thus I would much rather have a 12si at 100A than a CS130 which will be so much easier to wire as a 3-wire retrofit. (but you still have to deal with the ammeter). But again if you want reliable high amps a CS144 is the way to go.
