The 1991 Fords and earlier had a bad type of alternator that was infamous for catching fire for some unlucky owners. It also has low amps, which hinders "alternator charging" of the House batteries. The 92s got a newer, better, higher amp alternator, so it is important in that case.
(This was all discussed a while ago on Tech Issues with Mex supplying the gory details on the 91's alternator fires.) My 91 has that alternator, but it is doing ok so far. Fingers crossed.
Doesn't matter now of course, but I thought it might be the same thing with new "generation" changes that matter. AFAIK there are some recent changes to alternator regulation that also affect House charging, so people are getting DC-DC chargers. I don't know what chassis years are involved, but it could matter to some buyers perhaps.
Hmmmm, this is the first I've heard of alternator fires being common or infamous. Neither of mine had issues ('79 & '88...oops; '87 :)), and replacing an alternator with a better unit would likely be relatively inexpensive. So I'm not saying that an alternator is not relevant, just that it wouldn't be a "waste of time".
