Sounds like a short in one of the windings to me. Can you verify that the engine rpm is not exceeding specs? If you can modify the engine speed Id say slow it down and see what the voltage read is.

If it has a couple hundred hours or more, try cleaning the slips rings on the back of the rotor shaft. They should be very shiny and not black or polished looking.
