When the governor contacts close at ~30mph you will see ground on the terminal labeled 'TH SW TERMINAL'. Once ground is there (you could ground it yourself), the solenoid terminal will see 6V and the solenoid should engage. The 'TH SW' terminal will be floating if the governor contacts are open. Ken


...So the terminal you mention is floating and should get ground above 30mph
 
Get a test light and turn ignition key to on. Check for power on both sides of the fuse. If it is present the get a jumper wire and ground the top terminal, the one with the wire going to the governor. You should hear a click. Now check for power at the lower terminal, the wire going to the solenoid. You may also hear the solenoid energize which means you do not need to check for power.
If all that works ok with that jumper then you have a problem in your grounding circuit.
