Here's what's happening.

Battery positive connects to an ignition coil's primary terminal, and passes through the coil's internal primary winding which ends at the coil's other primary terminal, where a wire runs to a Dyna-S module and reaches ground through the module, whereby the coil "charges."

When the rotor's embedded magnet passes by the module, the coil's ground connection through the module is interrupted (lost), which causes the coil to fire through both spark plug wires.

After the magnet has gone on past the module, the coil is again grounded through the module, and is again "charged," until the magnet again passes by the module.

Points work the same way, where "closed" provides coil ground (charges), and "open" un-grounds the coil (fires).

Good Fortune!

i really aprecciate the help, a lot. Thank you! coming off each coil are two wires. one yellow and one black, which wire goes to the ignition. the yellow or the black?

On each coil, one of the two wires is feeding switched battery positive to the coil, and the other wire goes to the ignition.

Good Fortune!

Regardless of the color coding all you have to do is follow from the pickups themselves in determining which one goes where.

Example: See attached drawing.
The pickup-sensor on the left is for coil 1/4.
The pickup-sensor on the right is for coil 2/3.

Each pick up will have a red conductor attached to one end for switched battery voltage (after ignition switched to ON position).

Whatever conductor color the left pickup has attached goes to the coil used for 1/4 pistons.
While the other conductor attached to the right sensor goes to coil used for 2/3 pistons.

Maybe this will help...

F yeah! Thank you Old Man Rock and thank you for the added in coloring of wires. Patton, you guys both rock. Thank you so much! With out this site there would be a lot of Kaws out there spittin and sputterin.
