91 FJ70 3F no spark (1 Viewer)

[littlefj70]

I have been trying to trouble shoot a no spark issue for days on my 91 LC. I have tested 3 coils, replaced the points with a pertronix system that works in another LC I own and still I have no spark. I have read and re-read the manual I have and studied the wiring diagram as best I can; I am at a loss. I have a feeling its a wiring issue. Can anyone explain how the ignition switch and the coil wiring work together?
If i have power to the positive and negative sides of the coil what am I missing?

Any guru able to help out? I have owned these LCs for a couple of years now and greatly appreciate the Mud community.

Many thanks
