OK that does not surprise me at all. The motor has been repainted silwer. If I can get a wiring diagram that matches the relay/fuse panel and the LCD unit I should be able to get everything working. Apparently the harness I have was fitted and the bike was running before being taken apart
Hopefully someone will be able get me a wiring diagram or the closest one. At the moment my biggest stumbling block is a schematic for the relay/fuse unit.
Thanks for the help so far to all!

I would also pull the top end off to see what engine you have and what has been done to it. This will determine what you can or can't do with the bike. I have a strong suspicion that what was once a 120Hp bike is now in the 90Hp range. As I stated before, PM me your email address and I will email the diagram to you. Kawasaki calls it a "Junction Box" what you are calling a relay fuse unit.

I need the wiring diagram for this:


Called a "Junction Box" by Kawasaki. Depending on the bike, model, location, they are not all the same and are not all hooked up exactly the same. Much of this stuff is for the Fuel injection, and computerized ignition.

The frame serial # is definitely a fictitious serial #. There never was a zx1100B In 83-85 the models were zx1100-A1 threw A3. In 1986 the bike went to water cooled and turned into the C1. Looking at the instruments, this is not a US/Canadian model. Because the wiring diagrams were completely different between the North American models and the "Others" PM me your email address and I will scan the diagram and email it to you. It will be for the 83 model since I do not have it for the 84-85 model. You will have to do quite a bit of rewiring with the ignition, and most likely have to change it all together. Post a picture of the pickups underneath the points cover. This will tell us what the ignition should be. You won't be able to use the ignition box at all since it must be run with the injection computer. You will have to convert either to a Dyna ignition or a non injection Kawasaki ignition. What's under the points cover will tell us what options you have. Also, since your injection computer is no longer being used, you will loose most of the displays on the instruments.


The EFI circuitry and wires have already been removed and the bike was running without it, apparently before being taken apart. I am thus assuming that the ignitor, which fits the harness, was the one that the bike was running on after modded back to carbs.
Here is a picture of the pickups:

That is a late model ignition that will not advance without the injection computer. This means that the ignition must be either replaced with a Dyna 2000 or the entire ignition including mechanical advancer will have to be installed.

Looking at the ignition pick ups(pulsing coils) for this engine I see they have removed the mechanical ignition advancer and put in something from a later bike.

The 1982 engine was black,had FI,the fuses were the older glass tubed type with fuse clips,and a mechanical ignition advancer with different ignition pick ups.


Sorting out the wiring will have you pulling your hair one strand at a time.

Does the number on the Igniter photo show it as the original EFI unit?

Yes, I was afraid you were going to say that. Do you know what model will have a mechanical advance that will fit?

Fortunately he wants me to only get the wiring sorted out so that it can be started as someone else is going to get the motor sorted out....? I have some good news for him, new ignition system or an ignitor with advance built in or fit a mechanical advance unit. Makes me wonder how the PO managed to ride it

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.

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.

Keep in mind that the smaller 4’s (650 & 750) may have the wiring reversed, 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.



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 www.z1enterprises.com 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.

The advance is provided by the EFI computer, which you don't use due to the carburetors. You will have to use a Dyna 2000 ignition or, the MSD MC-3 ignition or go to a "J" series Kawasaki ignition with a Mechanical advance. The last option will make the ignition the same as what was on the 81/82 GPz1100. The MSD ignition is the best made and is the one I want to install on my bike once I go back to work and can afford it.
