Yup, cutout relay inside the control box most likely needs adjustment.
There's a procedure in the book, but most likely just turning the tension
adjustment (on the frame behind the cutout contacts) in by 1/2 turn or so
will fix the problem.  If you go too far, the light won't go out when you
start the engine.

Be sure to deal with it promptly; as the generator windings and probably the
cutout contacts are being overloaded.  Basically the generator is trying to
act like an electric motor but is stalled because it's not strong enough to
turn the engine.
