Customer Question

Onan 2.5KVD-5242B with 3.3 hours, ran for about 20 minutes on the road before we stopped for lunch, came out & it had stopped & won't start.
Checked the vent tube it has a foam cover over it & is clear. Will run with the start switch depressed but dies if let go. Oil level is full, what next.

Hello!
Thank you for requesting me.
This issue is most likely due to the genset no longer producing power, so that is where you need to start.
Connect an AC voltmeter to the output leads of the genset, and measure the AC output while holding the start button to keep the engine running for a few seconds.
If is is not producing 120V, this is the problem.
