Customer Question
I have a Generac...

I have a Generac Model 4948-5. The overspeed light comes on when it fails to start. The voltage measures 11.56 volt when it cranks, but it won't start.

Mechanic's Assistant: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?

It's on propane and pressure to the regulator.

Mechanic's Assistant: Do you plan on doing the work yourself?

Yes

Mechanic's Assistant: Anything else we should know to help you best?

It started twice this morning after cleaning the battery terminals but this afternoon, it wouldn't start.

Sorry, this is an industrial rated unit, and I am not qualified on it.

I will have to opt out and let someone else take over.
