[Missingyou]

Are you sure your generator doesn't already have a raw water flow switch. Many do, I found out the hard way. ;-) Long story short the o-ring on my strainer basket was missing after I took delivery. It ran for a bit but then the impeller finally gave up. It shut down quickly and would not remain running upon restart. They also may have an exhaust gas temperature sensor, as does mine. I assume this is to prevent a melted piston or valve?

See if you can find the original brochure describing the features of your unit.
