Re: [OMC-Boats] DimWits at Autozone

Do a google on "Prestolite ALK MARINE Alternator"

It is quite possible you only need a set of brushes which are still
available as well as other service parts if you have time and
inclination to look.

Why not take yours to a decent local motor/starter/generator
specialist repair shop and they should be able to check it out?

PRESTOLITE did stop making these in the early 1990's but they do have
a nice 37-amp MARINE UL-rated replacement, No 8MR2051XX see link:

You mention seeing 11 v, that surely doesn't indicate much if any
charging is present. Does your boat still have a working ammeter?
Don't forget the external regulator is also part of the package and
you will need to check that as well. As mentioned by Andy the newer
alternators have internal regulators.

For marine use the original ALK's were decent units if properly
maintained. Most people want to toss them in favor of the vastly more
popular 1-wire Delco, but I have gone the route of keeping/maintaining
mine.
