77 Ironhead
OK my latest conundrum, I about have my project road ready(their never finished) I got the sport back together and ran it up and down the street everything was fine, came out the next day fired it up and it was only running on the rear jug, But when I turn the key off it fires the front jug, pulled the plug wires switched them around on the coil still sparks the same wire on the other side of the coil, put them back, spark moved with it, I took the front wire off and it sparked the rear wire when I Cycled the key. I've tried different wires, Do I have a bad coil (discharging the windings,) Dyna module or maybe a short. I haven't had to work on the ignition but I have had to fix the wiring mostly lights and signals, and replaced a few connections, I have checked relays and such. any help would be appreciated.

 

Solved, Bad dyna module
