Or, if that doesn't help, the STC should include the voltage
regulator, a breaker and maybe even thicker primary wire. Try
contacting the alternator's manufacturer, they aren't so anal about
the STC's. They realize it generates business.

We are in the process of replacing the engine (O-235-C1) on our Piper
PA-12. The new engine comes with an Alternator. The existing
electrical system utilizes a Generator. I understand that we will
have to replace the voltage regulator in order to make use of the
Alternator. As I understand it, the voltage regulator is part of the
airframe, so we will need some type of approval to do this. I can't
find an STC for replacing the generator with an alternator on the
PA-12.

Can anyone help me with what needs to be done to get this approved?

Thanks.
