Charging system issues, bad stator?

[DO3]

I've got a new to me 2013 like 50cc 2T that has a charging issue and I somewhat stumped.

I've put in a new battery and it slowly drains as the engine is running, I measured about 2 amp draw while running.

I tried a new voltage regulator/rectifier with the same results.

While the engine is running and the stator is unplugged from the harness I can measure 50-65 VAC from the wires to the ground, once I plug it in the engine rpm drops 1500-2000 rpm and the voltage drops to 5-7 VAC. Also the current draw on one of the wires is 7 amps and 1.5-2 on the other.

If the Kymco 31120-LHB3-E10 stator was easier to find I'd just swap it out. Is there a different Kymco PN that is similar and know to work? I'm hesitant to buy a generic GY6 stator as that might be what is in there now. I can tell that it is not the OEM one as the ignition wire has been spliced.

Thanks for any thoughts

There's dozens of stators that fit, some with 2 wires, some with 3.  It's such a pain to sort them out that I just buy the correct Kymco stator and skip the problems. Same with the ignition ECM.

Welcome here!
This different voltage and RPM drop on your scoot to ground might indicate a faulty anchor.
But first:
-find and clean (metallicly) battery minus to ground cable point on your scoots motorbloc
-multimeter on battery plus and minus
-motor runs at 4000, VDC output at battery?
- 14 /14.5 VDC, stator healthy, fault in line

Renew the splicing before any other action with sturdy screw connectors.
No change at all?

I would simply risk a few €€ and renew the stator.
(Pls see pics) make sure your stator, pick up sensor and connector looks the same.

11.9 VDC at 4,000 rpm. The voltage at the battery actually goes up when I turn the ignition off

Would sound to me as there is a ground problem too.

ASSUMING:
-new battery and charged
-new reg/rect (the correct one?)
-"splice" changed to proper connector
-cables from stator to reg/rect checked cm per cm for a broken part (particularely where it leaves the motor bloc)

..then there is not much left as to think of a faulty stator coil.
This aftermarket stators are not too bad, I have used (not on a 50) them with good results and its not hard to change on this aircooled scoot.

Watch a few YT videos how to remove fan and stator nut safely.
Read that thread below too.
