New to the site and am wondering if anyone can help me with the ohms specs for my 82 KZ440D. I seem to be having failure in the ignition upon heating up. Am being told that the coil, pulse coil or the ignitor is failing. Want to test before buying parts as the cost is more that I paid for the bike. What a bummer not to be able to ride when I just got started.

I wrote this for the Kz1000's and Kz1100's but it should work for your bike(except for having two pick up or pulsing coils on them).

Ohm Checking Pickup(Pulsing) Coils

The pickup coils on the Kawasaki’s with the factory supplied electronic ignition can sometimes fail or become intermittent due to heat and vibration.

1.Trace back from where the pick up coils are mounted,(under a right side CD sized cover) locate and disconnect a small 4 pin connector. Using a multi-meter set on OHMS and range of X 100 check between the BLUE and BLACK wires(#1 and #4 sparkplug wires) for between 360- 540 OHMS.

2.For #2 and #3 sparkplugs the wire colors will be YELLOW and RED, again 360-540 OHMS.

3.If the pickup coils are suspect of failing due to heat, they can be stressed using a hair dryer without the need of the engine running.

4.A replacement set of pickup coils might be obtained from a dealer who serviced the police Kawasaki’s.

5. If replacement pickup coils are not available, your next choice would be to order a Dyna “S” electronic ignition system from Z1 Enterprises, Inc. - Specializing in Vintage Japanese Motorcycle Parts It replaces the IC igniter with a smaller module located where the mechanical ignition advancer was mounted.

6.Check the small 4 pin connector that the pickup coils connect to for corrosion/loose pins too.
