Your starter solenoid should look like the picture below. The terminal at the top has the positive battery cable connected. The "S" terminal on the right has a wire connecting to the start terminal on the back of your ignition switch. The terminal on the bottom connects directly to the starter motor. The "R" terminal on the left should be connected to the + terminal on the coil. This will supply the "bypass" necessary to get 12 volts to the coil while the engine is being started.

Just curious: Your coil isn't marked

12 v
No resistor needed

is it?
