Hi Scot

the 912ULS has a single phase generator with alternator. This should limit voltage to 13.7 to 14.2 or about that. If you see more voltage than this then it suggests a failure of your ground or regulator in the system. See the maintenance manual heavy for the testing values and wiring suggestions for the charging system.

Cheers

Scot, just to rephrase that a bit. It is a generator that has AC current that is limited by an external regulator to control the output voltage.

Cheers
