Re: Kohler generator wont start
I would start by shutting off main power first and let any existing errors clear out. Then push and hold start/run for a bit and see if it actually cranks.
I just went through this with a friend. He had pushed run and stop in some weird combo and got the unit locked up and it wouldn't start. Cleared everything out and then it started just with holding down the run/start switch.

Re: Kohler generator wont start
He had run the genset a few days before and it ran OK, then he couldn't start it... it would not crank. Could hear the fuel pump run (prime) but would not crank. I started suspecting the actual starter or the starter relays or solenoid. I had him open the genset cover and swap the relays hoping that would change things and nothing was better. We even thought there might be a dedicated battery for the genset that was low or bad, but that wasn't the case as it was served off the stbd mains. He had an older diesel genset before that needed the glowplug preheat when it was cold, so he was pushing the bottom button (off/prime/preheat) before run/start and that was somehow confusing the system. Even doing it the right way after that would not work. He did not have the controller display, only the flashing light and it was flashing codes when he tried to start.
Most generators will not crank until an "overcrank" alarm has been cleared out of the system.
However, that said...
Here is the Cummins/Onan troubleshooting steps for and "Overcrank" condition:

Re: Kohler generator wont start
I haven't removed oil pressure switch.
Any ideas?
