Stator and Pulsar coil readings

[mjcharger]

 My Agility 125 is having ignition problems and i'm running out of things to check. I'm focusing now on the stator and pulsar coil.

Can anyone compare these values to a working scooter? I checked the three wires coming out of the generator area.

Blue & Yellow wire: .4 ohms resistance, produces .4v AC when turning over.
White wire: .5 ohms resistance,  produces 9V AC when turning over
Yellow wire: .38 ohms resistance, produces 7 V AC when turning over.

Thanks

same problems here...2008 agility city 125...

pickup coil is giving me trouble....

sometimes is like working, sometimes aent...new stator...

What are the symptoms?

Axy,

I'm not getting any spark at all.

I tried changing the spark plug, changed ignition coil, changed the CDI, grounding the spark plug, checked the killswitch, looked for shorts in the ignition wiring. Thats why I'm asking for any information on stator voltage.

if stator doesent work u will get first spark..

try moving pickup coil foward to magnet....and screw it up

Ok I'll try moving the pulsar coil a little closer to the magnet on the flywheel. What about the low voltage though? I thought I should be getting 120 volts AC, not 7.

I just tried moving the pulsar coil closer to the flywheel. I also roughed up the magnet and pulsar coil in case there was any corrosion/ dirt etc. Still no spark at all.

check ignition coil wire to spark cap, and cap too.....unscrew them....

Ok I got the scooter working. It was a bad pulsar coil. I bought a new one and installed it and the scooter fired right up. On the new stator & pulsar coil I measured the resistance and voltage.

Key off:

Blue/ Yellow wire- resistance 111 ohms
Yellow wire- .6 ohms
White wire- .7ohms

Key on, scooter not turning over:

Blue/ Yellow-112 ohms
Yellow- 7 ohms
White wire- 6.8 ohms

Just turning over the engine:
Blue/ Yellow wire- resistance .9 killi ohms, .23 volts
Yellow wire- no continuity, 7 volts
White wire- resistance 0 ohms, 9.1 volts

Engine running:
Blue/ Yellow wire- resistance ohms, .76 volts
Yellow wire- resistance ohms, 11.6 volts
White wire- resistance ohms, 17.5 volts

Hope this helps someone save a lot of time when their trying to know if their stator/ pulsar coil is bad!
