not getting spark, bad stator or pulse generator?

[topdong1]

hi all,

i'm new to scooters, but not two wheelers.

I've got an 86 spree, that had spark. I cranked it over with the plug not ground properly, and i smelled that plastic electronic smoke, and lost the spark.

i've checked out the ignition coil, cut off switch, pulse generator, and stator and repalced the CDI unit. Everything agrees with factory spec except the stator. Manual reads 500-900 ohms, i've got 74, i think. I'm suppose to probe the black/red and ground, to test it. There is no battery, so i used the shock bolt and frame as ground, which gave me 0 ohms. My question is, is there another way to test the stator? I did have a dim headlight when trying to kick it. Has anyone had a stator go bad on them?

Another point to mention, in trying to get the flywheel off, i accidentally wedged a pry bar between the flywheel and pulse generator. Could i have possibly throw off the gap between them? Does anyone know the spec for it. Is that gap adjustable?

Thanks for any help.

More likely you blew the regulator, if anything.

If you pryed on the pulse generator it may be broken. Have you checked it?

is there any way to test the rectifier? Or at least bypass it to see if it'll spark?


The pulse generator seems ok, the housing isn't cracked, the wiring is good. The resistance checks out. If someone could measure the gap on their scoot, then i'll know if the gap is okay.
