I have a 08 Agility 50 scoot I can't get to start. Not sure what the problem is tho! I have no fire at spark plug. The CDI box has power to it! But, seems to have nothing coming out. There are two plugs on CDI. One with three wires & One with one wire. The plug with 3 wires none of them ever have power coming out. They all stay grounded! The blue wire with yellow stripe is crank signal wire from engine. The black wire with white stipe appears to be the wire that will shut scoot down at ignition switch. The other wire is black with some stripe which appears to be signal to coil to tell it to fire. How do I tell if CDI is problem or maybe crank sensor? NEED HELP PLEASE!!!!!!!!!!!

..are you getting fuel to the cylinder?
-
In the general section there is a thread called "links to manuals". The testing info is in the manual there. That is all AC fired wiring so it will read ground if testing with dc meter/test light. I would disconnect the "kill" wire to be sure there is no issue on that side, and get a NEW plug before trying anything else.

..i just brought that link to the front of the board...
..that link is pretty deep in that topic...
peace

maybe crank sensor?
UH, Have i missed something here??

How bout that coil???

Word Slinger at this point & time I'm not worried about fuel! I need fire right now.
The Batman coil has no power to it! It gets it's signal from CDI box. Which CDI gets it's signal from crank sensor.
The major problem is no fire at plug & trying to figure out why the plug with 3 wires at CDI all stay grounded! No fire coming out on black wire to coil.

Zombie which wire would be the "kill" wire? The black one with white stripe that goes to the ignition switch? Have new plug installed already too.

..sorry..thot i read that u had fire at plug..
..the black/blue comes off the kill switch, but from looking at the schematic, if you have nothing on blak/yellow to ignition coil, but do have power in on black/blue, only other possibilities are pulser, or the diode that's in the blue/yellow wiring circuit...or faulty cdi...
..did you get a look at the schematics in the service manual?
-
Word Slinger I'm not sure how to check pulsar to see if it's working or not. I have continuity from backside of pulsar to the CDI. But, I never get a true pulsing from it. Like I do when I test stator. Wiring schematics are a weakness of mine. I'd rather pull the motor than mess with electrical problems!
-
..section 15 in the service manual is where the info is...
..i'll look at it this evening...
:)

Thanks Word Slinger!

The wire going to the switch is a ground/kill switch. If you ground that wire it diverts the coil signal "killing" the engine. To test the pulsar is an impedance test. You will test the resistance to ground. The value is in the manual. I always take the easy way, and buy the cdi/stator, and install them one at a time to test. Then you wind up with at least one good spare. These parts go bad on a regular basis if you ride every dayI was going thru cdi at the six pack rate till I ordered on direct from Suitai. In four years I have bought three stators too.
To qualify the chewing up parts... I ride at an average 8,000rpm every day all day. I think Heat/vibration are the biggest problem for me.

..i likes zombies way...

..if you're not into schematics, then these test procedures gonna be tiresome...
-
Should have said the pulsar is part of the stator when ordered. I have had my pulsar quit, and I fixed it by removing, and sanding the base where it mounts. The aluminum case oxidizes underneath the steel mounts.

Thanks Zombie,
I bought this scoot used! So no real idea of condition when purchased. It has 4,500 miles on it & didn't run when I got it. I've found a online scooter parts store where I can get new CDI, new coil & wire assembly & a replacement pulsar for about 60 bucks. These parts are all specified for Kymco DC fired ignition systems. Was really thinking last night about just replacing them all for that price!
P.s. Thanks guys for all your help!

It is soo much easier... Scrappy dog is a good shop. They also have a forum for any issues with their products. Let us know how you make out
