Onans have a bunch of ignition kill safety switches. Most generators have only oil level. These even have voltage regulator and stator out put fail switches. Plus they have fuel pumps and fuel filters to look at.
So first thing is to get one of these https://www.harborfreight.com/90-in...43BTg65yY_aQ9OfX_RqOi1OE9Cv70hSBoCqmIQAvD_BwE
If youre getting spark need to test fuel pump/filter. Take bowl drain out and see if gas comes out. If so check spark plug to see if its wet from gas. If not clean carb jets.
If youre not getting spark check oil level. Also turn breaker to transfer switch off. Its located at the generators outside panel usually. If it runs after turning power off let it warm up completely then flip the breaker. If it keeps dying its a voltage regulator or idle or air/fuel mixture not spinning the engine at the right RPM. You can check RPM with a tool. If it keeps going omce its warms its probably lean.
