The stater safety/ interupter was tested. It was one of the first things I checked when I couldn"t get the starter to engage. I used a multi-meter and it show just over 12 volts at the solenoid when the key is turned while depressing the clutch.

Check the voltage at both of the big wires on the solenoid. The battery side should be the same as at the battery. The other side should be just a little less if the starter isn't open circuit. If the starter side isn't up to voltage your solenoid is defective. You will want to check the big wire on the battery side for proper voltage when you turn the key to start. You may want to check both ends of the ground for voltage drop. To do that you will connect one meter wire to the starter mounting bolt and the other wire to the ground side battery post. Then try to start the engine and watch the volt reading on your meter.
