This is ridiculous !!! With a battery and a couple of leads put a neg - on the solenoid body and briefly touch a positive+ on the spade terminals, one of them should make it click if it doesn't then it's duff.
If one of the terminals makes it click then that is the one that connects to the wire from the starter switch, the other terminal connects to the positive + on the coil for the cold start along with the ballast 9v from the ignition switch.
