Does the H panel have an external governor driver or is that part of the H panel itself?  Working on a 100kw Olympian that's all Generac under the tins.  I have little H panel experience.  Trying to find parts is a challenge even with a Cat dealer and Industrial dealer nearby.  Not sure whether it's a 60 or 68mm Bosch Governor.  Model G100LG2.  Leaving out the serial number because its a defense contractor.

The H panel typically uses an external governor driver, actuator (Bosch), and a throttle position signal conditioner. The H panel has the control and sends a PWM signal to the driver, the driver positions the actuator and reads the position back in analog from the signal conditioner.

Would need serial number to accurately search for parts.

Cat came through and the throttle body was down in Mass, brought up to the local warehouse this morning.  Was the 60 mm Bosch Governor, probably the same as the 70kw that I take care of.  Pulled the old one and it was locked up solid.  Swapped in the new and gasket and it ran just fine.  I held off on the driver on a hunch that the problem was with the governor itself and it was.
