I have a C90-12F in an experimental Zodiac 601 HD. The voltage regulator quit and the generator seemed to be failing as well when a field test was performed. This alternator wasnt much more than the cost of replacing both of those items and I am glad I went that route. This alternator is a direct bolt on item, the gasket that came with it fit perfect and wiring was simple and straightforward. It provides a much better charge than my old generator ever did, even at low power. The only downside I have noticed is it produces a bit more whine over the headsets. I would recommend purchasing a noise filter to be installed with it.

Installed quickly and easily. Hardest part was removing the gear from the old generator. Replaced a Delco-Remy on a C-85. Also remember to upgrade your wiring to handle 50 amps if you're swapping a generator.
