I have a couple of these outboards and believe that connector is power output for lighting.Re: "Hi Graham, Cliff has been in
Archimedes Penta 80 spark problems.
After testing everything else, I'm looking into the ignition bits under the flywheel. I see the front internal ignition coil, grounded at one end, is wired at the other end only to a 2-prong socket on the lower front of the motor. The other socket prong is wired to ground.
What is this socket for? Do I need to make some kind of connector for it? How does this work?
