The blue and white wires connected to the two "M: terminals are the kill circuit. The white wires from the CD boxes are connected directly to the internal capacitors.The white wires, while the engine is starting or running should have about 240 volts BUT you can not read this with a regular VOM because the voltage rises and drops so quickly. When the key is turned off, the white is in continuity with the engine ground through the blue wire. The internal capacitors are shunted to ground instead of to the coils and no spark is generated, stopping the engine.The blue wire is the wire that grounds the white when the key is turned off and while running or even stopped, will show no voltage.
As I said, it would be rare to have both charging coils on the stator bad. It would also be most unlikely to have both sides of both CD boxes bad. Note that the bottom CD box has both a yellow and blue wire connected to it. This is because each charging coil has a positive and negative side. (actually, it is a type of alternating current and I use positive and negative for simplicity) The top box uses positive (let's say it's yellow) for one cylinder and negative (blue) for the other cylinder. The second charging coil MUST have somewhere for the voltage to go so both yellow and blue are connected to the CD box. Later Force engines used (I think) Green with yellow tracer wires for the charging coils.
Whether or not your engine has quick-connects or is connected via a small terminal board on the electronics plate, check for broken wires inside the insulation. Trigger wires do sometimes break where they enter the trigger but no all three. Pull the flywheel and check that the center magnet is still intact as this activates the triggers. check the rim magnet strip because this charges the capacitors.
Hope that helps a little.
