Hey guys,

I am getting close to finishing my new build and first shovelhead, but I can't get any spark, I'll provide all the detail I can below. Bike was running well at the beginning of the winter. Any help is appreciated

1982 FXE Shovelhead, dual plug heads (only running one side), Dyna S ignition. Electric & Kick start
I have two wires going to the coil from the module, white & blue, each going to one terminal on the coil. The top terminal has the blue wire from the module and had a red wire coming off (which I have removed, assuming it was for the tach)
The bottom terminal has the white wire from the module, and another white wire (which I assume is power, and I have going to the "I" post on the key switch)
I tested the coil by disconnecting the Dyna S wires and measuring between each post, this produced about 5 ohms. So the coil is good?
New plugs, new wires, all the connections are solid.

When I turn the key on and measure the coil terminals (positive lead on one post, negative lead on engine case for ground) I get between 11 and 12 volts on both sides. This doesn't change if i turn the engine over slightly and measure again. One of the posts should be dropping to 0 correct? I am thinking this is why I don't have spark?
The engine will crank freely, but no spark. Am I wiring something wrong, or do I have a bad part? I can't think of how the module or coil would have gone bad over the winter, bike was running fine before.
Is there a way to test the ignition module to see if that is the problem? Does there have to be a ground connection for the ignition?

Thanks in advance
