Yes, most likely kill wires if black and coming from under flywheel. DON’T apply 12 volts to those wires. This motor doesn’t have a charging system. There was an optional generator kit available, but you probably don’t need it. The only load on the battery is the starter which doesn’t take a lot of juice. Unless you have have a bunch of accessories, you won’t have to charge the battery very often. I had a 1957 Lark 35hp on my pontoon and I hooked up a small solar trickle charger which kept the battery charged all season.
