Hello Gent's,
I purchased this kit for my son for Xmas. I worked on this for several day and I have no spark. I read the troubleshooting tips and I first found my magneto had an open, No continuity on my ohm meter. I stripped back the tape and found the smaller gauge wire was not soldered to the terminal. I fixed that but I have "0" ohm reading as in its shorted from terminal to terminal of the magneto. So I'm looking at getting another one. Mine has the Blue wire to the top terminal and the black wire goes to the lower terminal and a jumper to the metal bar of the magneto. I see that the replacement has a Blue wire to the top terminal and a white wire to the lower terminal and a seperate ground going to the metal of of the magneto. I'm reading that I just cut the white wire off and just use the black wire as my ground. My question is if this is a coil/inductor type circuit, Shouldn't I connect the Blue to the Blue and the white to the black wire of my CDI? Shouldn't I be using the coil connections like the original magneto was set up?

Any and all help with this would be GREATLY APPRECIATED.

Thanks in advance.
One frustrated Dad!

I used to just google that sh*t, now at 61yo YouTube is my new go to, hahaha. You shouldn't need to use the white wire for anything. The ignition is a weak point on these little engines. Junk right out of the box sometimes, other times running great and then nothing. Do yourself a favor and pickup a spare, test it to make sure it works first and keep it on the shelf. Good luck, hope you gt the kid on the road.

Thanks Gent's. Shouldn't the black wire be connected to the coil's lower terminal like the original coil was wired?

Well Gent's I got the new Magneto I purchased from Bikeberry. It was wired exactly how the orginal was wired and worked perfectly.
The bike started on the first try and my son now has a smile from ear to ear and is buzzing the neighborhood!

Thanks for all the help. It was greatly appreciated.

I see the difference in the new coil, the white wire has been eliminated and the black wire is soldered, this should be better.
