I pulled the flywheel and found the stator has been hot. Also found on the welsh plug the numbers 50273c and E 12791 making the power head a ‘72 Evinrude I think.
Not uncommon for those light green stators to have a little drool coming out of them….What reistance reading did you get when you measured the brown leads from the charge coil? Should be several hundred ohms.. The sensor leads should read around 40ohms. I think the sensor circuit goes through ground on this engine, so you only see one sensor lead, and a ground lead…
Correction…. I think it is the charge coil that has only one brown lead, the other leg goes through ground. The sensor coil has two leads.
