Onan generator switch?

I have a majestic rv and the inside generator switch does not work. I have tested it. Does anyone know where to get a momentary on-off-momentary on switch??? I have looked everywhere and can't find this. Any suggestions?

    Take the existing switch out and look for identifying markings.


    It says mcgill 0852-0284. The one I ordered is mcgill 0852-0180. Both have 5 poles on the back and switch up and down. The 0180 is not momentary switch the 0284 is momentary.

    I guess I need to check the fuse but I can't find it. I looked in the genset manual and it isn't listed in there.
  • Checked the wires and disconnected and reconnected. I can't find the fuse????
    I ordered this switch a week ago and it came today. It does not work because it is not momentary. It actually doesn't do anything which begs the question of the problem being at the generator. Because shouldn't it do something???

    Be careful about the switch. you need to get the specific switch. Onan part 300-5331 Onan switch is a standard switch with no hour meter.
    Have you checked the connections on the genset? What about the fuse on the genset?


    The switch that you posted above is not the switch that was part of the control panel. It was a rocker switch that fit into the control panel. I would like to replace it with the same switch it possible.
  • The switch still shut off the genset. Also I checked continuity from the pole to pole info I found and it did not have any continuity when pushed into the on position.

  • RV repair centers, ebay, NAPA, would be my guess or as said above at an electronics store.
  • Allied or Mouser Electronics.
