No spark

Does having the start button wires disconnected stop the plugs from sparking? I had disconnected the wires because the solder points broke on the switch

Disconnecting the starter button wires usually stops everything.

Actually in general, the stop switch feeds battery/alternator voltage to both, the starter switch, and the coils.     The starter switch goes to a relay which fires the cranking motor, as long as button is depressed.

Of course, w/out starter switch wires, the cranking motor wont crank. 

......but  once engine is running, if starter switch wires are removed, the engine should keep on running, as starter switch is open anyway if not depressed.   It is only a momentary held contact.     The stop switch in run position would continue feeding the coils and firing the sparks.    .........Am following my own wiring diagram. 

What all would a bad ignitor cause? I can't for the life of my figure out the issue is my spark, I checked the coils and they seem fine, and I put in new plugs and wires.

What bike is it and what have you tested up to now?

What voltage do you have at the feed side of the coils ( yellow or red normally) if you connect an LED test light across the coil terminals does it pulse when you crank the engine?

I have come across several bad Ignitor boxes on KZ650/750 models which would give a no spark situation.

First I would check for corrosion on the terminals to the box which is usually mounted under the battery box. This location sees a lot of weather so connections have to be tested. All the tests for the ignition components are covered in the FSM.

It is not uncommon to have one side of the ignition moduals to quit working but not both sides. If that is the case then the box is suspect.

You could update the system by running a Dyna S type ignition plate which has no Ignitor box.
