Re: Ignition switch for 73 Johnson
Fred.... You need a ignition switch that has six(6) terminals on the back of it labeled "B, C, A, S, M, M,". The "tan" wire you speak of, I think you will find upon close inspection, is actually white. However, I will refer to it as "tan" so as not to cause confusion.<br /><br />You can use a five (5) terminal switch as Bill states if you do not need the "A" terminal<br /><br />The terminals on the back of the six terminal switch and the related wiring would be:<br /><br />B (Bat) = Red<br />C (Choke) = Brown/white stripe<br />A (Accessories) = Anything you want 12 volts applied to when the key is in the ON position.<br />S (Solenoid) = Tan (Actually white?)<br />M (Magneto) = Black<br />M (Magneto) = Black<br /><br />The two black wires lead to the magneto points. When they are connected together via the switch, the ignition is killed, stopping the engine.
