I need a circuit to disengage power to the start switch which is separate from key switch when engine has started so there is no chance of accidentally engaging the starter with the already operating engine. I have the separate start switch and know how to wire it with a relay. You turn on the key then use to start button. But then the button must electrically disconnect so there is no chance of accidentally pressing it and engaging the starter when the motor is running.
I have repeated myself as I seem to get the same answers in how to wire up the start button! That I know how to do.
