Generator shuts down during exercise cycle on over crank. Went to test this morning. Unit started and ran for about 2 minutes and shut down on over crank. Anyone had this issue before on this model?

Is the fault light flashing or solid?  I'm not sure on this particular unit but many of that era used generator output to signal the board that the engine had started so if there is no AC output the starter typically reengages as it thinks it hasn't started and continues to do that untill it faults on overcrank.  Normally this is 3 crank cycles so it is unusual that it faults within a few seconds.  A flashing over crank could have another meaning.

I pulled a manual and checked the R200B panel uses a flashing overcrank to signal a faulty ignition module.

It is flashing. Thanks for the info. I was wondering if it was either controller or ignition module.
