Question about Electrical Supplies
See trouble shotting guide
Q. Why does my generator start and then shut down as soon as the start switch is released?
A. Most models require both oil pressure and AC voltage from the generator to keep running. A lack of AC voltage can
be caused by a variety of problems involving the control board, regulator, generator and wiring. A stuck oil pressure
switch can also cause this symptom. The interaction between the various components of the system can be confusing
during troubleshooting. Use the Troubleshooting Guide to isolate the problem.

You should if the fuel is enough and if the start motor is good or not

The problem is that you are not creating voltage. Remove front cover. Place a volt meter on the breaker. Start genset and you will see no voltage present. The problem could be with the brushes, rings, rotor, stator, voltage regulator, or control board.

First locate the oil pressure switch and see if you can bypass it,then see if it runs. If not check the fuel filter and fuel pump,make sure solonoid for fuel pump is kicking on.

ONANS ARE PRETTY QUIRKY AS IT IS NOT CONSUMER FRIENDLY. THE GENSET IS DESIGNED FOR ROUTINE AND SIMPLE MAINTENANCE PERFORMED BY THE OWNER, AFTER THAT, U WILL NEED TO TAKE IT TO THE NEAREST DEALER OR CUMMINS DIESEL REPAIR SHOP.

That knob should be to bring pressure up and down with 0 being off or the lowest range of the regulator. This regulator is adjustable for different applications apparently.
