I've seen plenty of charred Mopar instrument panels or firewall connectors over the years. The original design might have been okay in the 60's, but it doesn't hold up to modern electrical demands. The firewall connector is probably the weak link rather than the ammeter, but the ammeter will melt if you send enough current to it.

The Mopar engineers started to figure it out in the 70's. They ran heavy gauge thru the firewall on some vehicles and they started to shunt around the ammeter.



THIS is the correct answer

Mopar KNEW THEIR CRAP WIRING was inadequate, just research "fleet wiring."

I don't remember when? 72? or so? Furys and other "big" cars started using shunt ammeters.
