Check battery voltage. Should be 12.3 - 12.6VDC.
Lower reading indicates insufficient charge.


If reading ok, check for spent fuses. Clean battery terminals.


Try a jumper pack and see if it starts.

Contact your supplier to help you maintenance.
Because only they are clear about your product.
But if you consider to buy diesel generator set to supply power, maybe you can conatct [email protected] or visit www.dieselgeneratortech.com. They have focused on diesel generator set for more than 43 years.

SOURCE: Onan 4kw Emerald I generator will not crank

The gen. is not the problem, the engine start circuit is not functioning. You need to look at the starter solenoid and starter.

Why onan 7500 HDKAJ rv generator will not turn over.


If the start battery is definitely good then why is the starter not getting energized? Ignition switch? Low oil switch, on/off switch? Safety switch?
There is something that you are overlooking. Bet that if you take a wire and hook up one end to the + terminal on battery and the other end to the plus wire on the starter it will crank!!!!!!!!

Onan genarator will not crank


If it wont crank, check to see if the solenoid on the starter pulls in, the starter and solenoid are one unit, it sounds like an internal starter contact, if you have 12V going to it. Assuming the battery is good. When you press and hold the stop button does the fuel pump pump prime? if so control board has power

Onan generator service codes


Check the spark plug and the ignition coil for good sparking.

Get the spark plug out, or with another spark plug connected to high voltage cable, outside the motor, the outer part of the plug connected to motor ground and see if spark is present at cranking.
