Thought I killed my on board generator!
Which would have been tragic since it has now 9 whole hours on it and only been in my possession a week!
Pulling maintenance on our new to us camper, I changed the genny oil and decided the 4 years of dust and the oil I spilled needed to go. Because a clean generator is a happy one right?? Plus I’m OCD about stuff like that.
Gave it a once over since I’m not experienced with these built in Onans. Saw the control board front and center but it appeared to be sealed / potted in rubber.
Litttle spray with cycle wash everywhere and some de greaser on the oil spill and then hosed er down.
Miastake #1. Usually a run an engine while spraying/ cleaning it. Maybe a placebo maybe not. But I did not.
Mistake #2. The cheapo sealing job on the control board was coming apart on the edges.
Genny down for the count. Shorting out. Primer would go on by itself. Wouldn’t crank over .
Blowing air into the board it was bubbling soap water out the other side.
Pulled board out vacuum, compressed air etc. plugged back in temporarily. No go.
A little fiddling revealed the outside start switch would work sort of if pressure held on.
After doing that and getting it to start and heat up, problem is gone. I see a crack in the switch actually. So likely not all my issue with the water but nonetheless, a more important warning about the quality of the seal on the control board.
