Can anyone tell me how I can wire new electronic ignition to my 1978 LTD 1000 changing over from the
stock points to new electronic ign.I have parts with no instructions.It looks like I just wire to my
coils and use my old ignitor.Any help would be much appreciateed I am new to this forum and I am
in the middle of putting a 1980 kz eng on a 1978 LTD1000 Thanks Ray

Hello, Ray Riz, and WELCOME to KZr!
Which electronic ignition? Dyna-S? Kawasaki? Something else?
Neither points nor Dyna-S uses the igniter part of Kawasaki electronic ignition.
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 2K, 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. The 550’s,650’s & 750’s may be backwards to the Z1’s,Kz900’s,Kz1000’s & Kz1100’s.
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 www.z1enterprises.com It replaces the IC igniter with a smaller module located where the mechanical ignition advancer was mounted.
6. Checking with Kawasaki.com website has determined that the Pick up(pulsing) coils are available . The pulsing coil # is 59026-1133 and replaces the older # 1002, 1012 which were used from the MKII motors until the 2005 P24.
7.Check the small 4 pin connector that the pickup coils connect to for corrosion/loose pins too.
Ignition Coil Primary And Secondary Wiring
Ignition coils on the 80’s Kz1000,Kz1100’s and Gpz1100’s are wired the same, that is as you sit on the bike, the LEFT ignition coil primary(small wires) are two wires, RED and BLACK. The secondary (or sparkplug wires) go to #1 and #4 sparkplugs(your primary wiring may be different).
The cylinders are numbered left to right as you sit on the seat; #1,#2,#3, and #4.
For the RIGHT ignition coil, the primary wires, again are two wires, RED and GREEN, with the secondary going to #2 and #3.
The RED wire gets it’s voltage from the run/stop switch on the right handlebar switch pod.
The BLACK and GREEN wires connect to the IC Igniter(if the bike has the Kawasaki supplied electronic ignition) it actually gives the coils their grounds to fire the sparkplugs.
Primary(small wires) side of the coils will read between 1.8 to 3.0 ohms.
Secondary(sparkplug wire ports)side of the coil will read between 10.4K to 15.6K ohms. These ports are wired together, so it makes no difference which is used, as long as the correct coil to sparkplug configuration is followed.
The sparkplug caps should read 5K OHMS, any higher, or a reading of infinity means new caps should be ordered.
To stress the ignition coils, take a hair dryer, heat the coils and see if the ohm readings change from cold to hot . If they do, it’s time to buy new coils.
Keep in mind, the wiring is reversed for the 550’s 650‘s and 750‘s, that is the RIGHT coil primary will be two wires, RED and BLACK with the secondary(sparkplugs) going to #1 and #4.
The LEFT coils primary wiring would be again two wires, RED and GREEN, with the secondary(sparkplugs) going to #2 and #3.
These engines have what is known as a “Wasted Spark” that is, a sparkplug will fire during an exhaust stroke. It does no damage and many other motorcycle engines have this design.
If fitted with Dyna green 3 ohm coils on the points system that's being replaced with Kawasaki electronic ignition, am thinking that the 3 ohm coils are not a good match for the Kawasaki electronic ignition system.
On the other hand, the Dyna 3 ohm coils are a good match with the Dyna-S electronic ignition system, and with the old points system.
