True. GM alternator conversions in one of their flavors is by far the most common done over here today but in addition to Chrysler, Ford has theirs. Add to that if you have an older conversion, I know of at least one Packard that was converted in the 60s to use the same Prestolite alternator and regulator setup that Studebaker used. If your conversion was done in Iceland there are several European brands which could have been used and may be different from a US brand.

Another consideration is if you replaced the first burned out bulb with the number given on the forum which was for the stock Packard bulb used with a generator, it is possible the alternator needs a different bulb.
