The thing to remember about the puch is that it has four separate magnetos for the four electrical components. The first is obviously the ignition (the one hooked to your condensor..) the second is the light, the third the tail light and the fourth your brake light. If you just hook up the blue wire coming out of your magnetos (from the points?) to the live wire on your coil it should work. And ground the magneto?? I dont remember.. A one-wire coil is probably grounding through the bracket to the motor...
All of the other wiring is just to make the lights work and they can be bipassed. (not legal to ride though...)
Mine is hooked up in the following manner and DID run until it mysteriously quit....
(remember that three wiring harnesses make up the wiring, magneto, front, and rear.. find wires accordingly..)
Blue/coilpower{}black/black
grey{}grey
blueblack/greenblack{}blueblack
yello{}yellow
green{}green/green(I think the brake lights...)
Brown(ground){}coil ground (you dont have one...)
the colors together (blueblack...) are striped.
Hope this helps! If it still doesnt run ground the blue wire from the back harness (taillight..) just to be sure thats not shorting and try the horn thing. Then look at your switch (ignition.. mine sucks...)
