Hey everybody I need some help. I’m installing a dyna s ignition module on my 86 evo sportster bobber. I got the mechanical advance unit installed along with the module and coil. I have it wired up according to the instructions with the two wires from the module on the coil, I also wired the 12v from the ignition switch to the correct side of the coil. My problem is I’m still getting no spark. Does anyone have any experience with these that could help out?

Single fire right? Pics will help
How are you checking for spark?
This should be dead simple.
12v from ignition switch to the coil.
Power wire to the ignition module on the same lug of coil.
(Both should be white if using stock colors)
Signal wire from module on the other side (blue)
If you don't get 12 volts, check your switch(es), battery and
Ground(s)
If you don't get spark, ohm your coil and plug wires.
Check the plugs for fouling and proper gap too.
Most Harley coils don't care which way you wire them.
More important is to have the two power wires on one side and only the signal wire on the other.
If you wired the ignition backwards, you might have fried it.Comment

I used to hose clamp two plugs together so I could leave them dangle in space, and now I have a few pairs (any new plug will do, car or bike) tack welded together by the shells. Even a rubber band will do the job since they need to connect to each other and the frame or engine ground is irrelevant. (The engine connects the shells when running.)Comment
