Default Onan 2500/2800 remote crank not working

Onan model 2.5KVFA26120L, though I think all of the 2500 and 2800s are the same for the remote start panel.

I should mention that I had exercised the generator last week before a trip. On the trip we had a tire blow out. The blow out bent the generator exhaust pipe. The exhaust pipe is a solid pipe from the generator to the end of the pipe. So the generator took quite a shock.

I can crank the generator with the panel on the generator, but no crank with the remote in the RV. The switch appears to function correctly. Though the wiring diagrams are not clear to me. I have checked the wire from the switch to the plug just out side of the generator and all four wires are good.

On the switch side of the plug (male end) I can see that pins A & C connect for Start and pins A & B connect for Stop. E-F I think is used for the generator run light. On the generator side (female end) of the plug I see socket A is ground, socket B is battery voltage 12+ volts, socket C is 5.8 volts (this one does not seem correct) and socket E-F has no voltage/ground when the generator is not running.

So the question is why am I seeing 5.8 volts on socket C? Is this correct? When I short A & C on the generator side I expect the generator would crank, but it does not. Maybe because the voltage is too low.

I was really hopping to not have to pull the generator from between the rear wheels to fix it.

Any suggestions would be greatly appreciated.

I pulled the generator and replaced the control module with one from FlightSystems https://www.flightsystems.com/p-56-5299-00.html
Problem fixed.

Thanks for the followup and part link. Seems we've had a rash of non start problems with Onans lately. Congrats on the fix.
