Need help: 1981 Honda 70 3-wheeler magneto wiring

Well kinda off topic, but you guys are about the most realiable bunch i know and surely someone out there knows how to wire a magneto to a kill switch, to a coil. Wiring has obviously been played with on it a little thus my confusion, but lemme lay it out for ya: From magneto i have 3 wires going to a 3 wire plug, (the other end of said plug is MIA)
A: black wire, which leave magneto 1 to resistor, resistor to points, then resistor to black wire leading to plug, before plug there is a male female connector, it appears to be some sort of backup kill switch, when theyre plugged in all wires to plug are same length.
B: green wire, leaving straight from magneto #2 directly to plug.
C: lt.grn w/red this wire going from the plug, goes to a weird looking stud that appears to be ground, outside of magneto assembly on the engine.

Now from kill switch we have 2 wires: 1: black which runs down towards coil then ends in female connector. 2: green wire which runs from kill switch to could "ground" via coil hold down bolt to frame.

From the coil there is only a black wire which ends in a connector. Oh and obviously the spark plug wire.

I get hot coming from both green and black wires leaving magneto. I cannot get hot from the coil. The Lt.Grn w/red has no power.

I have two coils, no luck with either.

I will try to make a crude wiring diagram on paint and post up.

Thanks in advance, kinda embarrased i cant figure out something so elementary.

Mike
