How do you know when your CDI is broken?

Will your scooter misfire? Die completely? Not produce a spark? Work and then not work? Thanks.

Unfortunately......yes......
It can do all those things... You need to check(multimeter) the rectifier also to make sure you have the correct readings... Those are cheaper than the cdi.
I know there are several pdf links here somewhere for the manual

Here's what I am dealing with my scooter. It's having a problem producing a continuous spark. When I turn over the engine no spark is produced. When I turn the killswitch from on to off, one spark is produced and the engine does fire. That spark is produced right at the half way point of the killswitch being on/ off.

I've had the scooter start successfully before and have managed to ride it around. When I've wanted to turn the scooter off I've used the killswitch and it turns off just fine. Sometimes it would start just fine, other times it would be a pain. Now unfortunately, it doesn't want to do anything.

Here's one thing too I noticed with my Kymco that I dont have with my Lance. When I have the killswitch in the off position I can still turn over the motor and all the lights try to work.

What do you think is the culprit? The rectifier? CDI? The Devil?

It sounds like the kill switch itself is bad. As for turning over the engine with the kill switch in the off position, my S200 does that too and it's normal.

I called the Kymco factory today and talked to technical support. I told them what the scooter was doing in regards to the one spark. I was told without hesitation that it was the CDI.

I got a new one and the scooter started immediately. It's working great now.

The killswitch is fine too.

That's good to hear....
Glad your mobile once again...

Who would one call about this CDI issue. My bike runs fine, but at high RPM falls on it's face. Letting off the throttle and easing into it helps only briefly.
