One wire alternator with original amp meter gauge

[dougt69roadrunner]

I am restoring 1969 Roadrunner with all new wiring from American Autowire. Their new wiring requires a one wire alternator which I have. Problem is with the higher output alternators AAW doesn't allow for use of the original Alternator gauge (Amps) in the instrument cluster. They say it can cause heat at bulkhead and cause fire.

If anyone has ran across this issue I would like to know how you resolved. I have read about replacing the Amp gauge with Bosch voltage gauge but looking for another alternative.

Thank you

there has always been a problem with the amp meter to catch the mopars on fire as the insulation degraded that separated them from ground and let the amp wires short to ground then the fire dose it to your car. replace with a volt meter and leave the stock looking gage

There is, aways has been, a lot of Chrysler ammeter misinformation circulating about these cars. Ammeters don’t cause issues on their own. The fiberboard ammeter insulators don’t just degrade over time without terminal nuts being left loose or abused in some way. There are several ways to run upgraded charge path wiring, larger alternators and retain the ammeter function safely. If the ammeter was such an issue, every Chrysler product ever built since the early sixties would have burned to the ground by now. The charge path bulkhead connectors are the weak link in this original electrical system, followed by mis-placed loading at the battery.
