You lost a lot of voltage on this old weiring and switches.
I prefer a so called weired George mod,trust me you got a very strong spark, a must have!!!
I do it on my project bike and i will not miss it, the ignition power comes directly form the battery without detours.

Looks complicated but is an easy fix

If you have a decent spark from both then you can forget about coils,plugs, leads and caps...for now, and look at the tigger pick ups and wiring to the ignition box where I think your fault is.
You can trigger the ignitor by tapping the sensors with a magnetized screwdriver, it fools the pick up into thinking the engine is running.

They work by charging a coil, then discharging it. The discharging coil creates the spark.
On the Kawasaki system, the signal to charge and discharge the coil comes from the pickup unit. If the crank is not turning, there should be no signal from the pickup, so there should be no spark. IF the factory system is sparking when the ignition is turned off, that means the igniter is charging the coil when it shouldn't. This can happen if there is a crossed wire to the input of the igniter of if the igniter itself is damaged. Turning off the ignition will cause the coil to discharge and create a spark.
This behavior is normal for aftermarket ignitions which are less sophisticated, like the Dyna S etc.
If you disconnect the pickups and this still happens, you need a new igniter. If the false sparks stop when you disconnect the pickups, it could still be the igniter, but you will want to check the wiring for the pickups closely to make sure they aren't frayed and shorting to some other wiring.
You can make a new igniter pretty cheaply, but it is getting more difficult to get the proper HEI module.

I checked the voltage at the kill switch and with it off I get 12.4 on brown, but then drops to 10.5 in run. Looks like I need to do the relay mod to get a good 12v at the coils.

Or perhaps you just need to clean and repair the switch. In addition to dirt and corrosion, 35 year old lead solder can be brittle enough to break, causing increased resistance, intermittent function, or no function at all.
(I know this looks a little repetitive. I'm not trying to hammer you, I'm just too lazy to rewrite my previous post.)
