My generator runs for 10 seconds and shuts off. The overspeed light comes on. Any opinions? Thanks

Hello John, thank you for your question. If the light were solid, that would be for a high engine RPM alarm. This is normally an issue on older units when the brush pack to slip ring mating surface becomes dirty and the resistance goes up. The unit won't flash the rotor and never produces voltage. You can measure resistance at the 0 and 4 wires (center 2 wires out of the 6) at the voltage regulator and see what it rates. On that unit the rotor resistance should be around 19-25 ohms. If more than 30 or so and you need to take it apart and clean the slip rings and replace the brushes. The Brush holder assembly is PS10162299.Good luck with your repair.
