Taking the control box out was cake; thanks for letting me know what to expect on the cable interfaces, Chuck!

New control board will be delivered any day--should know if this is going to work soon.

Hi Kurt,

Sorry I didn't post earlier, I just got back from a +12K road trip in my 27mpg Dodge Caravan. I have a 7KW Onan generator in my 1994 HR Vacationer that had the exact same problem as yours. I fixed it by installing a rebuilt circuit board I purchased from Dinosaur Electronics.

Unhappy

Thanks, Steve!

Unfortunately, in my case, this did not do the trick. After replacing the A11 monitor control board and the K14 relay, no change in behavior was observed.

I knew I was taking a gamble by throwing parts at the problem, but I'm a little rushed for time. I'm prepping for a trip with the Rambler this coming weekend. I already have the coach in a shop for some other work, so now I've asked them to look at the solenoid wiring for bad grounds, etc.

Have you checked for good ground wires. I had a generator of similar vintage, same symptom. Sent off the board for inspection - board was fine. Problem was a corroded ground wire that was almost impossible to see.

Thanks Matt! That's the next thing on the list. Where was your bad ground?

This genny is not very accessible; the solenoid itself isn't visible at all from the front.

Sorry the new board had no effect- your gonna have to get to the pull in solenoid to confirm connections are secure.
Do you need a copy of the complete service manual !If so PM me your e-mail address and I'll send it right away ! It has a trouble shooting section for your problem.

I am going from memory of a coach I had for a few months, five years ago. I think the ground wire was inside the control box, possibly went from the board to a machine screw inside the box. Even with the board removed, I could not see it without moving the wires around.

Trace every wire, clean the connections, and avoid the temptation of "this one is probably fine."

Good luck and here's hoping.
