Neon coil alternative for GL1000, 1100 & 1200

I came up with an idea to replace the ignition coils with something more available and with stronger spark. I have a bucket full of 1100 coils and almost every one is cracked.
Here is what I did.


I got a coil pack off a 97 Dodge neon.



I first connected it to my test bikes ignitors and with the plug wires that came with the coils I attached some AC platinums for a Chevy truck to see if it would fire, it did.





Next I fashioned a bracket from some light 3/4" angle iron.




Excuse the welds, I was trying to use my MIG with a fan blowing on me.

The Neon coil is about the same physical size as the OE coils.




Since this is an experiment I used crimp on connectors to connect to an original coil harness. Connected the yellow (1&2) to the set that would be on the front, blue (3&4) to the rear set.

The center wire in the coil connector is the + (black/yellow) the wires on each side of it go to the coil on it's respective side. So the wiring could not be simpler.





I then took the coil ends off the wires from the coils and crimped them on the wires I already had on the bike leaving the resistor caps in place.










Sorry about the blurry picture.




Here it is mounted in the original location. It took a little modification of the bracket to get it located just right.

















The engine started instantly and seemed to idle better and not take as much choke to keep it running as it usually does.


Went for a short ride and it did run some better, I need to play with the spark plug gap to see if I can gain some more improvement but I am happy with the results so far.

You do need a resistor on a 1000, otherwise there is too much power running through the points. Probably burn them up real quick. On the one I did I used a 1.5 ohm resistor which got the amperage down to real close to the original coils.
Thanks Dave, Could I use the same original balast resistor? I wanna do a try and see if it doesn´t affect the Neon coil output.

Here in Venezuela, can be found some cheapier coils than Neon coils (e.g. Chevrolet Aveo, spark, sunfire, etc), I will try in next days and let You know.

Thanks Dave for all You´ve done about this, here is almost impossible to find GL1000 parts.
I used the coils from a GL1500 on my '78 GL1000, and they work great.

how much is the Customs fee if someone sent you parts?

I don't remember the ohm rating for the original resistor, I do remember I used an 1100 resistor instead.

What year GL1500 were the coils off of? I'm looking to do the same thing to my 78GL1000.

does not matter, they are all the same.
