I have a 1978 General with a moto marini motor. Does anyone have a wiring diagram? I have no spark unless I ground the blue wire from the magneto and the red wire also from the magneto I run it to the coil then I get great spark. It seems like I have an on/off switch in the off position but the only thing I see is a stop button and a fork lock with two wires attached to it. Any help is appreciated. By the way it's a General 5 Star.
