working on the vortex. The RPM gauge doesn't reliably.
Does anyone know how I determine what is wrong? Is it the guage or sensor?
Where's the RPM sensor located on the engine?
Where do I purchase the gauge or sensor?
I think you ment the fresh water tank.
That happened when the float switch failed and overfilled the tank. and or when tank was full and we were on a steep hill. I don't overfill the tank anymore.
