I have an NP-30G generac, what happen was that the magnets

Customer Question

I have an NP-30G generac, what happen was that the magnets on the rotor came loose and of course it is not available any more. I found a machine shop that was able to glue them back in place and balance the rotor. I replaced the stator and the CCG board all other components test ok according to the service manual but when I start it up in accelerates up to speed stays there for less than a minute and shuts down its only reaching between 92-96 volts. I've adjusted the throttle linkage according to the manual no difference in voltage reading. Could the problem be in the distance that the magnets are spaced from the stator?

It's possible that the magnets are too far from the stator, which would result in a weak magnetic field, and low output voltage. But that should not cause the unit to shut down.

What you are describing sounds more like a bad genistor.
