Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, bear with us; re-confirm and post back with the complete model number of the "...2005 kawasaki..."

Still, let's do a review / check of the basics of a CDI:

  • check or for test purposes disconnect the KILL wire;
  • verify presence of pulsating low voltage from the pickup coil;
  • and for high pulsating voltage from the capacitor charging coil;
  • if all 3 above check good, then there should be pulsating voltage from the CDI to the ignition coil.

All of these voltages to be checked when attempting to start.
