Generator prime comes on automatically

2007 Fleetwood Discovery 39V . Onan 7500 QD. 150 hours on gen set .
This morning I walked by the RV and heard a clicking sound . After opening the generator shroud I found that the start and prime switch was illuminated and the prime pump was on . The rocker switch was not in an on position. I toggled the switch a few times and the prime pump went off . Any ideas other than ghosts , cats and squirrels in the compartment ?

Mine did that a few times never did figure it out doesn't do it any more. I thought it might have been rain running down the windshield dumping right on top of genny switch.

Typically caused by moisture in either the emote switches or the wiring harness. A lovingly-applied hair dryer sometimes fixes it.
