My dad worked @ a chrysler dealership for 16 years + and says he never heard of any incidents involving ammeter. Only thing that happened to me was Amp gauge burned the strip behind it but not the wiring or anything else. That was 1st time he says he saw that occurrence.
Depends likely on when those 16 years were. The newer and the larger platform cars went to external shunt ammeters. I've seen several "back in the day" (early 70's) and one was my own 70 RR WAY before Al Gore invented the internet, I drilled out the two big ammeter wires terminals in the bulkhead and ran larger wires "straight through" the connector. I had to take the cluster apart (plastic cluster housing on a 70 Ralley dash) and repair the loose ammeter terminals.

So far as Mattox comments, I see no reason to differentiate between cars or trucks. The circuit in the trucks was the same. Only difference in any car or truck, is the size of the alternator and the amount of load on the circuit.

Ma knew early on how to fix this----and didn't. Probably saved "her" about 5c per car
