What year was your Suburban John? I'm looking to see if there are any Chinese made alternators out there that get the kind of mileage your Suburban got. The problem doesn't seem to exist across the board with later model vehicles though. It seems to be as Dave indicated that it is the aftermarket high output units people are putting in their 1500s. Could it be that car and bike manufacturers require their parts to meet certain specs while the low priced off brands have no such standards? I guess what I'm getting at is, is it possible that the budget units from LActrical and DB Electrical are nothing more that cheap knockoffs the Chinese are famous for?
Even if it has a different brand on it if it was made for Honda (Honda dosen't make any electrical components) it could be made to their specs for a certain application. The alternator on a GL1500 or 1800 is pretty well enclosed and subject to more heat than on a car that has some air flow in the engine compartment. Aftermarket alternators are just car alternators, probably cheap chinese knock offs, adapted to fit the motorcycle and may not have the heat resistance built in.
Just my theory.

With no God over the state, the state then becomes not the defender of liberty but the definer of liberty.

If I disagree with you it's simply because you're wrong.
