What is the full model and spec number of your genny.(so I know which control board it uses) Onan starts and stops by switching grounds to control board. the center terminal or common terminal on the switches is grounded.
So if unit starts ok, you know that the ground circuit is ok.
If it will not shut down from either switch location, then likely problem is control board.
another possibility is that the "kill" wire to ignition magneto has come loose, preventing the control board and both switches from stopping the engine
