Another way is to take an ohm meter, take all the wires off of the solenoid, one lead to the power in post and the other to the metal shell of the solenoid. The meter should show "OL" or open circuit, if it shows any number or reading that means the solenoid is shorted to ground internally. Do this to both terminals, you can also do this test with the solenoid out of the car.

The governor can be tested simply spinning the input and having an ohm meter hooked to it also. You need to spin it fast enough to close the contacts inside the unit, once closed the meter will have a reading but before it closes it will read "OL".
