"A 2G alternator's biggest issue: an under-capacity rectifier and power connector (A). The connection and large, hollow case cavity were corrosion-prone, which increased resistance, causing voltage drops and heat build-up. Result: early unit failure, and even electrical fires"
https://www.hotrod.com/articles/install-high-output-ford-3g-alternator-older-fords/According to that, the 3G came out in the 94s, not the 92s like I said. So that means you could not spot a 92 by its headlight shape, etc and know it has a 3G. If the 94 C has a 93 chassis with a 2G, that would be a problem for me, but it is all history now.
I do imagine the same sort of thing can be happening with more recent model years.
