Charging problems

I purchased a second 125 manual engine and I am having some issues with charging and lights.
2 yellow wires from engine. Neither have ground by themselves so i wired 1 to ground and the other I wired to the white AND yellow from the frame harness.
If I unhook the battery it's only outputting 6v.
If I set my multimeter to 200 ohms both of my engines read 30 on the multiMeter across the 2 yellow wires from engine.
I read that mike had issues with a pink and yellow stator before and I read one other post from 2 years ago were something similar happened.
Could it just be a junk stator?

Is the engine you bought meant to be 12V? I believe the lifans are, but I could be wrong on that.

You need to know what configuration your stator is set up in. Usually if it's delta wye or star it'll have 3 white or yellow wires coming out of it. If it only has the 2 it's usually just a single phase.

If it's just the two, and they're 6V, one needs to go to pink on the harness and the other needs to go to yellow, no grounding anything. Don't use white because that gets turned on and off by the headlight switch.

Let us know more when you get a minute. - Kyle
 
The two yellow wires are usually the two legs coming from your stator that produce AC power. They should be connected to a 4 wire regulator/rectifier. That should provide 12 volt power for coil, lights, horn, and keep your battery charged.
