I recently bought my first boat,a Chrysler 16 ft Bass Runner with a 70 hp Chrysler motor.The ignition switch stuck so I went to the outdoor shop and bought a new one.The old one is marked battery ,accessory ,ignition ,starter,my new one is marked battery, accessory, magneto, magneto(grnd),starter, choke.My question is do I have the wrong ignition switch or does the ignition wire go to the magneto spot on the new one?
