Ya, very little voltage at the stator leads, on the CPI JP50, so I'll be replacing it. When I look for the fasteners to remove, it seems like there is body plastic in the way. Is it normal to remove plastic to service the stator? Or am I looking at this the wrong way?
Thanks

I don’t think I’ve ever had to pull body panels to get to the stator on any of my scoots. You’ll have to pull the fan cover off on a CPI should be 3 fasteners and a screw at the top connecting to the cylinder cover, remove the flywheel with a appropriate removal tool after removing the nut holding it on, then you’ll have access to the stator which is secured by 2 fasteners.

maybe the engine plastics.

It's very cold here and I can visualize that plastic cracking at the slightest strain. I'm not quite into my new repair digs yet and the heat isn't worked out properly, so I don't leave it running as of yet.

The exhaust will need to come off. The foot peg bracket might be a problem. Then you should be able to remove the engine shroud to get to the fan and flywheel.

Hmmm... that passenger foot rest might be an issue. Hopefully you can get the fan cover past it because that looks like it could be a pain to remove. If some fasteners are difficult to reach you can usually pull the seat bucket out with just 4 bolts.

Dagnabitt, 16°F here and the unican won't open. On the mandoor: the deadbolt is free but the knob is frozen. I know what my next investment will be.

y'er a bunch of jinxes...not only did I need to remove the top plastic to get at the fan shroud, I'll need to remove the floorboard to replace it. I suppose I could have drilled some holes but that ain't kosher in my kitchen.

Well, I got the stator out and I'll be darned if it doesn't pass all the bench tests for resistance and isolation. I must have loused up the measurements when it was all together with the engine running.
I'll put it back together and take the dynamic readings again...any ideas?

inspect and clean all connectors associated with that circuit, maybe ohms check the connectors to be sure you are not loosing something because of bad plug connections? id also check your ground circuit as well. could be a poor ground hindering the charging circuit

Scoot connectors are cheap crap. The crimp connections to the wires can fail. The connector blades often oxidize and connections are lost. Many are gold plated but the gold plating is very poor quality.

The crimp connections to the wires can fail. Wow, I didn't think of the crimp when you called out the connections. I was only concentrating on the stake of the M and F spades. I guess a resistance test of the wire from one spade to the other. I have a very nice insulation piercing probe, but I'm not so keen to leave poke-holes unless it is unavoidable.
Anyway, I'm in a holding pattern with this Arctic Blast, fixing furnaces, jump starts, pulling stuck vehicles from the snow, and all the other emergencies that go along with it...oh yeah, and getting my mom's groceries so she doesn't need to brave the wind-chill.
