I am getting no spark. I have replaced the coil and the pick up in the distributor. There is a Thunderbolt IV breaker less ignition module that I believe is original equipment. I am told that this part rarely goes bad. yet I have no spark. There is power to the coil. There is one wire (looks like a 110v house hold appliance wire) coming out of the stern drive and I can't figure out where it goes. Anther wire just like it comes out of stern drive and goes to a breaker near the fuel filter and is in tact. Can any one advise me on what to do?
