Hi,
Sounds like an alternator output to me, but before you hook it to your
battery, run the engine and put a meter on it to check it's electrical
properties.

Does anyone know what the 2 wires in a blue covering, coming out of the
flywheel area, are for? They have connectors on them, but don't connect to
anything. I suspect it might be for alternator output. It is a pull start
motor.
Thanks
