Mopar performance alternator 1or 2 wire???

Out of curiosity, what’s the typical issue with the bulkhead connectors? Just rewired the car with a ron Francis kit but kept the bulkhead connector. Took it apart and installed new terminals in it but kept the bulkhead connector to maintain separate wire harnesses between dash and engine.

Will that solve the problem? Plan on putting a more powerful alternator on later to power electric fans and such

I don't recall (without looking it up) does your car have the BIG feed through terminals for the ammeter? I think these are screw terminals. Mopar did this one or two, then skipped a year. If you have the regular size bulkhead terminals for the ammeter, this is part of the problem. If you have the very large feed through that is normally NOT a problem. Other areas of voltage drop are simply "follow the path to the VR from the battery. So main problems are ammeter circuit through the bulkhead, ignition switch and connector, bulkhead terminal for the ignition "run" feed.

One way "around" is to electrically cut the ignition "run" feed coming into the engine bay. Us the key switch end to trigger a relay, feed the relay from the starter relay, and hook the switched contact to the engine bay end of the cut wire.

Other concerns is making sure the firewall/ block/ battery all see a good ground/ common, and that the VR is grounded to that
