I have twin Honda 50s, 1995. The starboard engine will not turn over, no clicking or other indicator that electricity is at the engine. My volt meter says there is power at the starter. I switched all the wiring at the controls as well as the ignition modules. Also swapped the starter, stator, coils and what I think is the solonoid. Still no power on the starboard. Port engine runs and starts with no poblem. New batteries, clean terminals. Suggestions?
