I repainted the engine, changed gear oil, new spark plugs, new fuelfilter and so on. I conected the quicksilver conroll box to the angine and tried to start it after service. It wont start. I checked it and there is no spark. There is a White cable with black stripe on the quicksilver box. Do I need to connect this cable somewhere? I found in the attached file that this cable is for Bias Circuit. Doas anybody have an idea? Maybe I forgot to cennect a cable? THe engine was running fine until I removed it from the boat.
