I have Onan 8dkdfj s/n G953409883 spec. 11304c generator.

Customer Question

I have Onan 8dkdfj s/n G953409883 spec. 11304c generator. Alternator belt broke last week and it shut itself down. Changed the belt. Now it starts fine but will only run as long as you hold the start switch on. Was running beautifully prior to belt breaking. No idea what has happened.

If it helps to know this Onan is in a 1996 American Dream MH motorhome

If I hold the start button down for 60 seconds or so the generator supplies power to the RV... soon as I release it the Onan dies

Also checked oil level after new belt was installed and it's full...

Still waiting... any ideas please?

This most often happens when the genset is no longer producing power.

But since your belt broke, it is very possible that the belt took out one of the safety switch wires, such as the low oil pessure, high temperature or low coolant switches. Check carefully for any missing/broken wires.
