I just purchased a 1969 25 hp Johnson outboard. Some one had already changed the original push to start button. I tested the push to start button and it is bad. I see 2 wires hanging down out of the flywheel that are not plugged in to anything. I want to install a ignition switch that also kills the motor when it is turned off. I think the 2 wires may be wires that when grounded will kill the spark to the spark plugs. I am afraid that if i ground these 2 wires to test my theory and i am wrong i may damage some thing in the electrical parts under the flywheel. Does anyone know if these 2 wires are for killing the motor or are they for something else? Right now i am pulling the choke to shut off the motor. Thank you!
