Generac information

Troubleshooting information:

My Generac electric start generator starts perfectly but quits after about 10 seconds. Then it won't start again until it sets for about 1 minute. After a minute it starts on the first try, runs 10 seconds and then quits again.

My first thought was a sticking float in the carburetor. New carburetor - same thing. It turned out to be the oil pressure sensor switch stuck. The control board has a 10-second timer that kills the ignition after 10 seconds if oil pressure is not detected by the switch.

Good info, it will likely apply to others too.

It would have been nice if they had had an indicator that came on to show you that the shutdown was due to no/low oil pressure.  I hate 'safety' features that are silent, how are you supposed to know where the fault is?!
