ive got a 454 hardin marine motor with a prestolite alternater model no. 8em2002fa that currently took a dump. so im looking to match it with something a little more powerful but without having to make any modifications to mounting and wiring. the alternater i have is a 2 wire and the only thing ive found that matches is this Prestolite 90 Amp Marine Alternator but its a little pricey. any suggestions?
