Something a lot of people don’t know about those old boxes is that there is a cap on the bottom of the solenoid you can unscrew and remove with your fingers. There is a button under the cap you can push up on to crank the engine. By pushing it, you are manually pushing the contacts together to power the starter. Good to know if you have added a key ignition and lose the key, or have a malfunction with the wiring to the dash, the mercury switch on the throttle, or if the solenoid coil has gone bad.. Be careful, because it will crank regardless of the throttle position, as you are bypassing the mercury switch, so you could start it in gear at full throttle.
