SOURCE: 10kw Generac shut down overspeed

Make sure that the throttle linkage is all there and not damaged/misadjusted, then get a manometer and check your inlet gas pressure. Gas pressure should be 8 inches of water column and stay there running or not.

SOURCE: No voltage output

It is possible that your voltage regulator is shot but before purchasing the volt regulator try flashing the fields first and make sure the brushes and rings are clean.

when power tools get old they draw more amperage. 6.8 amps new might be 8 amps. over loading when older.

Sounds like Generator mode switch should be "ON".

Did you remember to set the overspeed shutdown threshold on the control board?
