Onan 10 KW Generator control board plug burned

This story started in 2019. We were parked overnight without power. It was hot and the generator quit. I tried to restart. It sounded like the generator ran out of fuel. It ran for a few seconds and then quit. The next day we took it to a repair shop. The Technician said that the plug into the control board Wasn’t sending power to the fuel pump. They disconnected the plug cleaned and reconnected and the generator ran for a year and a half. We were Boondocking one day and the generator quit. I remembered what and where the technician had done the repair before I cleaned and added a little dialectic grease, and the generator ran for several months after that. This became the routine for the next four years. Clean, grease, run. Last November I took the coach to Cummins for generator maintenance and talked to them about replacing the one female pin in the plug that sent power to the fuel pump. They recommended replacing the full wiring harness (6 Grand). I broke the retaining clip on the plug so I asked Cummins to replace the plug and inspect/squeeze any loose pins, paying close attention to the pin that powers the fuel pump. They did and reported the offending pin was good to go. The generator ran for 2 hours then quit. Clean, grease, run for 9 months and everything worked as before. The last time the generator quit and would not start I found that the plug is burned. I think now I will need to change out all the pins or the entire wiring harness as well as the control unit.

Has anyone had a similar store? Has anyone replaced there wiring harness on the gen set?

Thanks for reading and responding to my generator story.

Run a fused and switched 12v line direct to fuel pump. Best to mount the switch next to Gen start switch so you don't forget on/off. This is known issue on 10ks.

Six grand huh? Was the guy's name Ben Dover

Thanks this would have worked before the plug burned up. Also if I had installed the manual fuel pump power it would have eliminated the auto start capability.

Still looking for help on DIYing the burned plug issue.

Thanks for the suggestion. I didn’t know this was a common problem on the 10KW unit. Wonder what Onan was thinking when they made this one different.

Onan 10HDKCA burned P1 to Control Board

Finally getting around to fixing this issue. I found one burned socket in P1-3 and two missing pins 3, 14 on control board. I ordered a new control board from FlightSystems. I ordered a new plug from Cummins. I saw in a book at the Cummins service center that they have the sockets already crimped onto a short wire so that it can be butt spliced onto where the old socket was cut off.

I was unable to find these sockets with pigtail on the Cummins site. Has anyone had to replace any sockets in the plug going into the control board?

Would you mind taking a picture of the pin, so that I can go check mine out. Or could you describe where I can find the control board? thanks

the cummis site is a royal PIA to find things. Their plugs and pigtails are a bear to find. I find it much easier to google what im looking for until i find the plug number and then go back to the cummins site.. You can go to any Freightliner, pete, or KW dealer and they will also be able to look these things up for you as we all have access to the generator side of things as well..
