In the everlong course of trying to get my bike on the road I've had quite a few frustrating setbacks but this one has me really pissed. For whatever reason between a teardown in July and a few weeks ago I lost spark to the right cylinder. Checked everything I could think of and settled on the coil. Got a used set and still no spark. Ordered a new Dyna3 and still no spark. Both coils will produce spark with the green signal wire from the Dyna but neither will from the red signal wire. Someone suggested the timing was off but even if it was wouldn't both sides still spark albeit at the wrong time? Plugs are out and I'm testing ground to frame. All new wires, plugs and caps.   |

The dyna is just a switch, so you are right, it should fire whether the timing is correct or not. I take it your green and red are the leads to the coils? If you can swap them and get the coil to fire it sounds like one of your dyna pickups may be bad. My dyna on my cb has been flawless for the last 3 years. The one on my RD lost a pickup after about 100 miles.
Make sure you have 12v to each pickup . If the one pickup isn't powered it won't fire. Usually they are a shared power connection. But may be different in your case. Your pics aren't coming thru so I can't tell what it looks like.

Thanks. Power comes to the top coil, jumps to the bottom coil, then goes to the Dyna. I'm wrenching on her tonight so hopefully I'll figure something out. We hacked into the harness to power the head and taillights so I'll back that out and see if that's part of the problem.
