What color are the wires you are talking about? They may be for charging a battery, but I would like to be positive about this before saying for sure. I can check the wiring schematic and give you a definite answer.

The wires I am talking about are both green.

These wires deliver A/C current for accessories such as lighting. In order to charge a battery, you would have to add a rectifier/regulator, which would not be very difficult. I don't know why the manufacturer does not include this in the manual start models. You could look up the parts that you would need at the Yamaha website, but you would have to use a model number that corresponds to an electric start version of your engine.

I wouldnt plan on charging much with a 15hp motor. It's probably only around 10 amps
