thank you

thank you. will give this a go before it gets dark.

I run the 3TB TCI on the first generation 4PT engine, from 90 its a TCI not CDI, but searching internet all named CDI.

Thank you. I ran a continuity test on the connections on the TCI/CDI to the ignition coil and it seems to be .2 when it set to 200 ohms. I have the last model 4PT, looks about the same connection/box and same 5 digit number.

The box original to the engine i have is green label 4PT-82305-01 So if you have same box you know the red label 3tb works, but i run it with 3tb wiring, 4PT box works aswell on the 3TB wiring. Thinking you have bad connection somewhere.

To measure is to know.
Guessing does not help.

Get a workshop manual.
(At least this part)
And use your multi meter.

And be systematic.
Measure coil by coil. CDI box if possible.

The CDI system does not use battery.
It uses a two specific coils on the generator.
My money is on that the problem is there.
A simple resistance measurement will give the answer.

=

The very old Kawasaki H2 had a CDI system.
With two coils. High speed and low speed.

=

There is one test than can be done, besides measurements.
Try to push start the bike. At as a high speed as possible.
Than the high speed coil starts to work.
And the engine will be running as long as you keep it at high rpm.
But stop when you let it down to idle.

That would be the proof that the low speed coil is bad.

=
Let us know the result. So we can improve our knowledge.
=
You wrote that you had measured on the three pin connector. And all gave same value.
Strange.
Measure on the side towards the engine.
Between to pins at the time
The three reading will show values for
a) One coil
b) The other coil
c) The two coils in series

Look up the values in a works shop manual.
On another bike that I was working on the values were
5 Ohm
200 Ohm
For the two coils

Measure each of the three pins toward earth.
I shall be open circuit. Else there is a short circuit.

The picture

Green: Coils to feed the CDI system with current
Yellow: Coil to trigger the ignation
Red: Charging the battery

Blue 1 and 2: The high and low speed coils.

Pick up coil have to pin wire and value 184-276ohm

Stator coil resistance white-white 1-2.1-3 leads one is the top one 0,52-0,78ohm

Measure your clutch switch, neautral relay and sidestand switch to make sure all is working curcuit.Need any more values let me know.

thank you both

i am unable to push start it.

i have a workshop manual, although it's for a 1990 xt the layout of the clutch and neutral relays seems different and i can't find them.

side stand switch functions correctly with continuity.


The pick up coil blue and yellow to green and white is .229 with meter set to 2000.

And then with meter set to 200

i have again tested the three pin connection. top and left 0.7
top and right 0.7
left and right 0.7


will check for the earth tomorrow from the three pin.

i can't see your useful diagram at the moment.

You have 229ohm its correct. Thats because the 3tb dont have same stupid security with clutch handle in for starting bike, on yours its conncected to the neutral switch relay if i remember correct. You dont have same relay, they change it to diode.

None of these is what I wrote about.

Stator => charging system
Pick up => triggers CDI

I talk about low/high speed coils.

Any values for them ?

Measure on the side towards the engine

White/Red to Dark Green
White/Green to Dark Green

Using Kawasaki values:
On should be 200 ohm
The other 5 ohm

And both shall have no connection at all to earth

=
An earlier post stated that the 3-pin connector has nothing to do with ignition.
That is not correct.

I attach a complete wiring diagram



Red == Charging
Yellow == Pick/up triggering
Green == Current to CDI

Already given them, its low and high speed from the 2 wires directly to TCI. You are on the wrong engine, you have CDI old engine, we are on the new model from 1996.

Sorry,
but I am confused,

What are the correct resistance for

a) Low speed coil
b) High speed coil
???

I found it.
=>

Pulser coil resistance

green - white/red 90-130 ohm

green - white/green 90-130 ohm

white/red - white/green 180-260 ohm

Below is a picture valid for 2003 model

Nr 19 is the part I am talking about.
With 3 wires W/R, W/G and G

thanks for diagram

unless i am really missing something, here are the connections coming out my alternator that i tested yesterday. they are all white on the three connector. they don't seem to be going to earth, which is something positive

i am thinking it might be time to buy that 3TP TCI box, at least it would rule it out

Well its the pickup cable hes talking about, two wires! I understand you get confused about all this writing and digram for other bikes. What i find a little strange is your bike is so clean on pict, and the TCI box was really dirty, have bike been under water? Thinking short in the box? Even connections was full of dirt. Buy the TCI box and test, if its not correct you can resell or have as spare, at that price its cheap to have in safety for testing.
