I have a 1990 15hp Evinrude with electric start. Starter good. I grounded the neg. from the battery and tested the starter button and don't get any juice from the pos. wire when pressing button so its bad I guess. Question can I just by pass the neutral safety switch and install regular solenoid and start button and hook It up with a standard start button like I do on 18hp motors and by pass all the starter equipment that is there. Thus making it just starter button to start it. New buttons are $60 and I have regular button and solenoid.
