Motorcycle Repair/Coil Spark

Question
Hi Mike, you answered a previous question about my 1986 Softail
Custom  that I am almost finished rebuilding. Thank you. It helped
perfectly.
I now am ready to fire it up. As I was testing the bike, I fired it up with
plugs out to check oil pressure. That was fine. Then I noticed no spark
on plugs. I realized I wasn't energizing the coil, so I ran a wire from my
ignition to the coil that made the coil hot when ignition turned on (I used
test light to confirm this). But still no spark when I go to start it. I have
two wires, one white and one blue,
coming from the stock electronic module that are connected to the coil.
The white wire is on top and blue on bottom as service manual says.
Plug wires and plugs are secure. The module is grounded. Any ideas on
why I'm not getting a spark? Many thanks in advance.

Answer
If you have power going to coil and the modual wired correctly then the only thing it can be is a bad modual.
Couple of things. You do have the hot wire to the coil connected to the top of the coil? When you check the spark, you did have the plug grounded to the head? Yuo do have the cup behind the ignition modual?
Good luck and happy riding
Mike
