1967 Barracuda alternator upgrade question

Hey Rumblefish,

Thanks for your reply. I don’t have the testing equipment but think it would beneficial if we could test the Ammeter to the point of failure.

I would have thought the Chrysler engineers would have specified a gauge where they only used up to 80% of gauges rated amperage to achieve a continuous duty rating. So, theoretically if the stock alternator made 35amp they would have specified wiring and the gauge for 42amps or more.

It would be nice if testing could be done to know how hot he gauge gets under continuous amperage load on the gauge alone fails to put all of this into perspective.

I’m going to go with the 78amp alternator and bypass the ammeter for for now. At some point I will send my gauge cluster to redline gauges for restoration and voltmeter conversion since I’m not aware of any better options.
