Diesel Onan 8000 Start/Preheat Light
We are at the Norwalk OH races and the last few days the preheat and run light on the start buttons no longer light up on the generator.
The generator starts and runs fine it is just the light on the start run never lights up on start or run on either of the buttons in the bedroom or at the kitchen area which is normally used. Anyone have this issue before? I did look at the 3 fuses on the DC circuits. Any suggestions would be appreciated. Thanks Rick Cates Canyon, TX |

Mine quit working on the inside switch. Still working on the outside one. Been that way for several years. Still works fine. Must be a lamp that burns out or vibration kills it

Re: Diesel Onan 8000 Start/Preheat Light
Several years ago I was in Charlotte for the Points race and then the National Event the following weekend. At the points race my generator quit working. It would fire then die. It was flashing a code.
I found this web-site where there is a ton of knowledge for the Onan. After reading similar threads I tore the unit apart in KB's parking lot and replaced the rubber drive coupler that had cracked and broken from age. Lucky there was a Cummins dealer in Charlotte. Might check these guys out. https://www.smokstak.com/forum/forum...-generators.1/ Robin

The rocker switch lights routinely fail
Nothing is wrong with the generator, you just need to replace the rocker switch.

I did check and the switch on the generator is still working and the generator still works just fine, just no lights on the two remote switches on the inside of the motor home. Will the Cummings/Onan dealers have the rocker switches? I am sure I can change the switch if I can get a direct replacement. Thanks again to all who responded and I feel much better running the generator. It is hot and humid and we need the generator and air conditioning here in Ohio. Thanks again, Rick Cates Canyon, TX |

Re: Diesel Onan 8000 Start/Preheat Light
If your remote panels/switches are ONAN items than yes you can buy the switch from Cummins-Onan or from some other suppliers.
It usually has one connector with all wires and only goes one way with a plastic retainer. Wall plate has to be pulled out. Here is a link to the part number and a picture of the typical Onan switch. Some were amber, but most now are red.... https://www.amazon.com/Onan-Cummins-...0BGSSXH7AZ38M7
