Onan Generator blowing fuse while trying to start, please help

Hi, I have an Onan Marquis NHM spec H LPG generator. It was working fine then when we were heading home the generator would crank but not start. It blows the fuse on the bottom right of the outer control panel within about 2 seconds(possible F2 fuse but the service manual does not mention it). I have replaced the ignition coil but that did not help. Any Ideas? I'm leaving on a trip in the morning and would like to be able to fix it.

i looked at the owners manual. the f2 fuse 'provides short circuit protection for the autochoke and fuel pump circuits'. i'd start looking there.

Would that only apply to a gas model? I did check that the throttle opens all the way to rule out the electronic governor

There is a relay that has one black and three white wires. I pulled the one that routes to the left and tried to start and it did not blow the fuse, problem is my service manual does not have legible wiring diagrams to see where it goes

my bad! it did say for gas models. no fuel pump on an gas model. try contacting onan and see if they can explain what that f2 fuse protects on a propane model.


this is just a wild ass speculative thought with only no basis to being true. i had a problem with our propane 5500 where it would crank but not start. it turns out there is a propane fuel solenoid down where the propane line connects to the generator. there are two electric wires that clip to the terminals and when these are energized they open the solenoid and allow the propane to flow into the generator. in our case one of these wires had come loose. i'm just wondering if yours has something similar and if that f2 fuse would blow if you had a short circuit in this solenoid. again pure speculation! i do not know!

No worries, I appreciate the help. I thought it was weird that there was no mention of the fuse for LPG. I called Onan and they said to call Cummins to get service. Cummins said it was too old for them to work on (2002)

I will check that out and see if I can find a loose connection
Thanks
