Default Re: 1936 starter button HOT!

The floor switch has nothing to do with the ignition or any other circuit than Battery-Switch-Starter. Because of the high amperage of the starter this is a heavy duty switch. This is why on later (1937 on) there was a solenoid (heavy duty switch controlled triggered by a low amperage signal).


This situation could easily have progressed to a fire. If the floor switch gets hot the battery needs to be disconnected NOW! If the motor still runs the generator also needs to be disconnected NOW! There is no fuse protection. Expect arcing when the battery (and generator) is disconnected as there is high current flow. Gloves and face protection would be a very good idea.
Thanks, for this answer. I disconnected battery roadside, new button will be here today. Hope I didn’t do something stupid to cause this, like resting my foot on the button. Greg
