Re: Optional charging system for 1970, 25 hp Johnson?
Some of these came with a generator for 12 V lights, but the rectifier was missing. I parted one or two of them. As this model came with electric start too, they must have had a charging system too. I think I have a couple of the generator coils floating around, but as I am in Denmark it would be easyer for you to get one nearer by. I am sure the 1976 - 1981 rectifier could be used, and is easy to put on. Look for a stator plate on e-bay or elsewhere. The coil should just sit on the empty space across from ignition drive coil.
