Hello all, I am having some trouble trying to figure out the wiring for my 1980 15 hp electric start evinrude. This motor was given to me off of a pontoon boat. The wires were all cut before I got the motor. There are many splices, not sure of the original wire colors. I have the key switch and kill button. I wired it the best I could and it started and ran and the kill button stopped the motor. However, I took it out on the river it ran great for half and hour and then it gradually lost power until it finally died. It would not restart, the battery was dead. It was fully charged when I started with nothing using battery power. I think I have it wired so that the battery is supplying the power for spark. Does anyone know where I can get a hold of a wiring diagram. Thanks Jake.
