Super Jet Stator problem with spark

[Germanrider]

Hello
I had a problem with my spark this weekend.
Ski does not start.
Try it with break cleaner to check if there is a fuel problem.
Check the spark. Spark was okay at the beginning but when I check it Again it only fire up when I release the start stop button. Changed the start stop. Same problem
Changed the whole stator and the problem was fixed. ( old stator was also set in the right position for timing ) Now I want to rebuild my stator. Check the resistence of the coils and they are in spec. Only checked it out of the ski so it could be a temperature problem.
Could it be the pulser coil or anybody has a different idea

Heat it up and check it again, around 185F.
The Charge Coil will be the culprit.

 

[Germanrider]

Why do you think the charge coil is the culprit. I know normally they have a problem and I still changed them on two other skis but they had a different error indication.
Not giving a spark when I release the start button like on this stator.
But Please let me know why it is the charge coil

 

[OCD Solutions]

Just based on experience. The charge coil is what "charges" up the capacitor in the CDI. If it doesn't produce enough voltage, the CDI doesn't charge as high and you get weak spark.
Testing it at temperature will confirm which coil it is.

Lighting coil charges your battery, Charging coil charges the capacitor in the CDI, pulse coil just tells it when to fire.

Right and I don’t have a weak spark I have a spark only when I release the start button so I think it could be the pulser coil but good idea to heat it up and check the resistance then

I already had a similar problem, it was the Charge Coil

 

[Germanrider]

Heated it up to 185f measuring lines have a resistanceOf 0,9 ohms so everything looks good.
Checked it at the end of the wires and also moved them to check if there is any broken wire.
The ski rundgehest with a different stator so I think there can’t be any problem somewhere else. Any idea how I can check this stator otherwise to find out what’s wrong with it ?

If you can't measure an issue, the next step would be to start swapping components and see which fixes it.

I'm not saying it's the Charge Coil but I purchased 5 Pulse Coils and over 50 of Charge coils when I started offering Stator testing and repair services. I don't have a single Charge coil left but I do have 4 of the pulse coils still. Just sayin...

Okay I also changed many of them but I hoped somebody can tell me a better way to test the stator and figure out what is the problem instead of changing the parts the whole time and test it in the ski and when it’s another part do it again

Cranking output test. Warm the stator. Cool the stator. Resistance test.

Thats about it

The best way is on a test bench. As far as I know, I built one of only 3 in existence.

 

[Germanrider]

Really nice but you check more than the resistance and change some parts you you have an instruction what you check

 

[OCD Solutions]

I do all the same checks as the OEM manual describes, I just have more control over RPM so it makes things easier to find.

Your next step is to verify voltage output of the coils while cranking which is around 700-900RPM.

Okay so I can check it on a old motor which will be placed on the workbench. Do I have to take care about anything when I do that ?
