I think if you goto Onan or Byrant RV you can download the service manual and schematics
we do have an Onan expert who is a member and very helpful..
maybe he will see your post
did you run the generator and then measure the voltage with the Onan running
the pump will be controlled by the control board and there will be NO voltage unless it is running
could be there was a control board failure, and the MOD was done to avoid buying a new control board
Thanks for the reply, I havent measured the voltage from the K4 wire yet, but you confirm what i was thinking as well
Thanks for confirming for me that the FP is controlled by the control board
Wont be able to work on this until this weekend
