Where is breaker on Onan generator?
The 25 amp AC circuit breaker is located on the side of the control panel below the 5 amp DC fuse and to the left of the fuel filter.
Why is my Onan not getting any power?
If your Onan is running but you are not getting any 120 volt AC power (e.g. the microwave oven or the air conditioner) inside your Roadtrek the most common cause is that the circuit breaker on the Onan has been tripped. Remember there is a couple of minute delay between the starting of the generator and the transfer of power into the Roadtrek.
What to do if your Onan circuit breaker has tripped?
Remember there is a couple of minute delay between the starting of the generator and the transfer of power into the Roadtrek. But if several minutes pass and you still have no power, it is likely that the Onan circuit breaker has tripped. Step 1 : Locate your Onan.
Where do you put the Onan on a Roadtrek?
It will either be behind an access door on your Roadtrek or hanging underneath in the rear center. If your Onan is underneath using some ramps made from 2×8 boards will provide a bit more working room. Step 2: Remove the access cover. Put a finger in each of the latches and pull up and out to remove the access door.
What to do if your Onan generator starts then shuts down?
If there is no AC, proceed to check the field flash voltage through the field flash pin of the board. In the case field flash voltage is not present, the control board may be defective. If that happens to be the case, the “Onan generator starts then shuts down” issue could be taken care of by replacing the unit control board.
Why does the oil pressure switch on Onan generator stick open?
The oil pressure switch of Onan generator often sticks open in case the unit has not seen any use for an extended period of time. In many cases, the situation could be resolved by multiple start/stop cycles, some light tappings should work as well. 2. Defective Control Board
Why is my Onan generator producing low AC voltage?
If field flash voltage seems pretty normal, the regulator could be the source of problem which you could determine simply by running 12 volts through a diode to the regulator pin 9. In the case the generator starts producing normal or slightly low AC voltages after that, the regulator is definitely defective.
What should the resistance be on an Onan generator?
Use the multimeter to check the resistance between pins 9 and 10 of the plug, the appropriate reading would be around 22 – 28 Ohms. If the reading is too low, there could be a short in the rotor. On the other hand, if reading is too high, it’s highly likely that there is a ground in the rotor .
