Ok Tim, ignore everything I previously posted......

A DKD is a completely different generator from what I was thinking you were talking about.

You have an industrial type open unit. I rarely see them anymore....

I cannot find anything in the service manual or operators manual that clearly says what is used for crank disconnect as it is called.

Something inputs to the control board mounted in the square switch box area to signal the engine is running.

If I was working on it and had a visual on it I could better tell you what it has or doesn't have.

Some Onan's used a simple switch that worked off the governor.....as speed came up the switch opened....I don't think it has one but would have to look for it.....Speed is fixed on those machines and does not have a governor.....Uses injection pump stop to set speed. It might still have that switch and it might be under the rear cover area.....generator end...

Might use AC output.....Might use alternator output....possibly oil pressure......

I have not worked on one of those in years......
