Dodge Neon coils on GL1000

I've had my bike for about 20 years. Done frame off restoration 16 years ago. Last week i lost 3 and 4 cylinders. I knew that could mean one bad coil. Checked fire and nothing at 3 & 4 and very weak 1 & 2. I found guys recommending Dodge Neon coils for the 1100. Looked easy, got a coil for 10 bucks and installed. There are only 3 control connections, center pin is power then a ground lead for each set of points. (per info i found)
The layout of the 4 spark plug leads is as follows (it is mounted like an H turned on side) the top two leads go to 1 & 2 Bottom go to 3 & 4.
I have monster spark at all 4 plugs, but it backfires like crazy when i crank it over but will not start.

Did not know which breaker points terminal went with which spark lead so i reversed the points connection, still same back fire.

Any ideas?

I was swapping the wrong wires. Didn't realize at first but the wires to the condenser share the same 3 way connectors with the points wires. Thought of it while i was writing the original post. When i swapped the points wires and tried, it cranked immediately. I'm real happy with results.

Good to hear the update. A picture would be great showing where you installed them and how you secured them.

You might want to read the posts by others who have tried this on a 1000. The Neon coils are very low ohm for our bikes. I have a set sitting on the shelves, but they are 0.6 ohm. You would be a lot of ballast resistance to be able to use them safely with points or with Dyna electronic. Wasn't stock about 5 ohms and Dyna wants at least 3 ohms?? Some of the Neon's had a little higher resistance, but not much. The one case I'm remembering led to burning out the start switch. Others were very happy at first because you would get such a big spark, but it may come at a cost. Keep us informed. I would love to see this work as the coils are dirt cheap.
