no spark, tried everything I know

[crassius]

as I understand, the wire is off the mag coil - vibration is great there, so soldering is required - a quick tap with just a 100watt gun will do it (a 250watt may hurt the coil & don't forget to tin the wire first)

The white wire will only have a fraction of the turns the blue wire gets around the core.
It is about 6 volts per pulse while the blue is much higher, like 60 or 70. ( I forget) There are two separate windings on the coils with a white wire. The more turns around, the higher the voltage induced by the magnet. The white wire won't have enough juice to fire the CDI.
I posted this just so folks get an idea of the electrical function, so they can troubleshoot more easily.

I fixed the blue wire connection to the CDI ripped the white wire right off and soldered all my connections. Sure enough it fired right up and ran good for a while until I ran into other issues...they aren't electrical related though so I suppose this thread can be closed

I'm glad my little help page helped you.
I think you will find your meter to be very helpful for a lot of things like if a fuse or bulb is bad or a battery or AC outlet is good.

I don't use the stock wires on my builds.
I put the CDI where I want it and then run a 16G double insulated wire pair from the magneto lugs...

To just a couple of off-set pig-tail wires left on the CDI...

Hook the kill button up there and just cap it off by epoxying a little hobby box on top.

That little box is also a good place to put a little ignition disabling switch, in that Fito's case I used a keylock switch, but any switch small enough to fit in the box will work, just tie it in with the kill button and mag wires.

I also always put an NGK 5944 (BPR7HIX) Pre-gapped Iridium spark plug in and a really great reliable spark is the result and sure worth it to me as a builder.
