Onan generator only runs with switch held in

I talked to Onan last week and they gave me a name and phone number of a customer service person to call so I passed that info along to my repair guy. Today I talked to the owner of the repair shop and he told me he called and talked to the customer service person from Onan and he feels confident he will finally be able to get the voltage regular next week that he's had on order for over 2 months. We'll see and if it does arrive, we'll see if that was really the problem.
