So basicly i was riding to school i rode abot a mile or two and then suddenly out of nowhere i lost power and the engine shut off. Pushed the scooter home and after a while found out it doesnt have spark and the spark problem isnt with the spark plug i tested that. So any suggestions why would it suddenly lose spark?
-
Run-stop switch in stop position?
-
Doesnt have a run stop switch
-
Please tell us more about your scooter:
Year, miles, previous issues, recent servicing, aftermarket parts?

the spark problem isnt with the spark plug i tested that
Deficient spark plug cap (https://www.youtube.com/watch?v=fZrIptLsMTI) or loose ignition coil connection?
-
Its a 2009 model if im not wrong. It has 2153 miles. No previous issues. No aftermarket parts. And the most recent service was at about 1k miles i did an oil change and i cleaned the carb because the scooter was left untouched for a while but it ran great everything was ok and then the spark issue happened.

Guys i found the problem. The ignition coil is broken
-
ignition coil is broken
Additional context may be helpful to others researching.
Was the deficient ignition coil (https://www.google.com/search?q=3051A-KHC4-900&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjFiqqWoenhAhVJHDQIHc77C6gQ_AUIDygC&biw=1280&bih=621) Ohms tested?
-
Yes i tested it and no reading.
-
Ok so UPDATE: there is a problem i think that it wasnt only the ignition coil that died or the tester just doesnt work right
-
Yes, I am not surprised. I started with a 2009 Kymco Agility 50 and it had a run-stop switch on the right handlebar. A bright red one. Same side as the starter button. I can see all kinds of situations where this may be missing. But if it is missing there should be, or could be a substitute start button. So what I am saying is I have a lot of questions to ask just to try to understand what your situation is, the "tester" you are using and how you are using it. So if you can be a little more detailed in your descriptions maybe someone could help you find the problem.

Yes i tested it and no reading.
No reading? or zero resistance?
-
The tester is a multimeter. Its just called a tester where i live and thats why i wrote tester. And there was no reading at all with the old and the new ignition coil. And i was testing it by the video tutorial on youtube.
-
Jarik, Since both the old and the new coils tested the same ("no reading at all"), I would suspect the tester itself or maybe incorrect operation of the tester. I suggest testing another type of electrical component to make sure you understand how to get a reading with a multimeter. Then let us know what you found.

Ok so guys i got the tester working and i tested everything from this video https://www.google.com/url?sa=t&source=web&rct=j&url=https://m.youtube.com/watch%3Fv%3DPnzsuRAV-Ro&ved=2ahUKEwiVnbXDgPbhAhWSwcQBHROsAM0QwqsBMAN6BAgFEA8&usg=AOvVaw2KYk7Sgi3raTX-CNb8if7z (https://www.google.com/url?sa=t&source=web&rct=j&url=https://m.youtube.com/watch%3Fv%3DPnzsuRAV-Ro&ved=2ahUKEwiVnbXDgPbhAhWSwcQBHROsAM0QwqsBMAN6BAgFEA8&usg=AOvVaw2KYk7Sgi3raTX-CNb8if7z)
And everything seems to be ok but still no spark. Any sugestions?
-
And by tester i mean multimeter.
-
Doesnt have a run stop switch
Yes, it does! You just showed it to the world on your video! Har, har!
You have an EXCELLENT video! Well done! I was impressed by the built-in voltmeter on the battery! That's neat! Also impressed by the logical steps through to find and then prove the cause. Good use of your multimeter. This was so good sorta makes me wonder the original intent of your post! Some of us need to ask YOU for help!
-
Very good follow-up. Glad you found it.
-
By the way that aint my video i still dont have spark and dont have anythin to ride because my 2 stroke gilera dna has issues with electrics. The video is one i followed to check my scooter and everything seemed ok but still no spark. So yeah NOT MY VIDEO.
-
Ouch! OK, sorry. Do what he said. The only thing he said that had nothing to do with no spark is the routine he went through with the solenoid. We knew it worked because he cranked the engine several times!

If voltage reading from stator to CDI is normal . . disconnect key switch pin from CDI to determine if that circuit has a ground fault issue. If engine does start, disconnect pulsar/trigger/pickup bullet connector to stop.

Jarik seems to have checked all components for continuity/resistance and found none to be the problem. So, your suggestion of testing for voltage, beginning at the stator seems logical next step to determine where the ignitdion voltage stops. I guess at that point you'd look for a bad connection of some sort?
