No spark in Cylinder 2 and 3 was created by KZP1000
I have a 2000kzp with 19k on it. I cannot seem to get spark on 2 and three cylinder. Ive replaced plugs and wires, pick up coil, and ignitor still no spark. Am i missing something. The only thing i havnt tried is putting the red and black wires from the 1 and 4 coil onto the 2 and 3 coil to see if its the coil or wire issue.

Do you have more than 12vdc at the coil?

Well i found the problem. My ignitor was melted again! This is my second ignitor in three months. The original one heated up so much it was smoking as i rode then started melting. Second one i purchased used off ebay. What could be causing the bike to eat ignitors? Maybe time to switch to dyna system?

A shorting coil could fry the igniter. Same thing would fry a Dyna S. The factory system is better than a Dyna S, What ohms do your coils measure?

You basically have two ignition systems so if it's always the same two plugs that don't fire, you can swap parts and circuits to identify the bad part.

What coils did you get? What ohms are they? If they are less than 2 ohms, that could explain frying the igniters.

The coils are a reproduction of the original. Ill check ohms. Thanks.
