I’m working on a Kawasaki Bayou KLF400 for a family member that doesn’t have spark. I’ve already replace the ignition switch and the stator which were defective. The stator had a melted connector and one of the phase had low resistance and low VAC output.
What I’ve figured out so far is that I’m not getting 12V to the ignition coil when I turn the key to the ON position. From what I understand, the 12V should come from the CDI. I’ve resistance tested both wires going from the CDI to the ignition coil (Green/white and black/yellow). They are fine. The only 12V coming from the ECU is on the yellow/red wire.
I don’t have the wiring diagram for the 400 but I’m working with the one for the Bayou 300 which looks pretty similar except for the wire color between the CDI and ignition coil. On the 300 diagram, the yellow/red wire goes to the ignition coil, not the black/yellow… All the other wires color match except for this one. Not sure if that’s normal?
