You have the black and red wires switched on the coil, swap them and hook blue to blue and the black to black for the engine output wires.

Or its garbage like a lot of stuff they sell.

So I have to cut the wires and hope its not garbage

Maybe, maybe not, I see they depict it the same way online, maybe leave the wires..

Check all your connections again.

It's real hard to hurt a coil. Sometimes they put the connectors on backwards.

 

[Frankenstein]

It might not be the coil, could be the box. Could be a bad mag from shorting something somewhere.

That`s the same cdi I run. It works either way red/black( -/+), or black/red(-/+). I swapped the black/red to suit my own wiring configuration. Bought three of them, and all still working. Another connection causing the problem perhaps?

How are you mounting your coil? If you are using the post opposite of the red wire connector to mount to the frame it is grounding out. I'm not sure of the KMB cdi's, but all of my perf. cdi's have red wire to the spade connector black wire to post.

 

[Kelly to fast]

A coil works by collapsing the field. It will spark even if hooked up backwards!

 

[Nature girl]

Yes, if you mount the coil by the two ground bolt holes to your frame you will have to change the red and black terminals. That`s why I changed mine, it seemed to have no impact on performance in either combination...both did work though.
best luck with it.
