I recently acquired an Onan Gen-Set 4.0 BFA 1R/16004B. It starts up with starter switch on "ON" and runs just a few seconds and then shuts off after releasing the start button. How do I fix it?

Hi, my name is***** will be assisting you.

You either have a relay bad or the genset is not producing any voltage to make the relay work properly. Can you test the voltage output and see if you are getting anything when cranking the machine or prior to it stopping?

You can test for voltage at the control panel of the machine unless this is mounted in an rv then you will need to test for voltage on the output wiring from the genset to the rv wiring.
