I did the gy6 swap on my 150cc. I was able to drive it 1 day to work and back and when I left for work this morning all the lights that run off of the voltage regulator, headlights, dash lights, etc. won't work unless I hold my rear brake lever on? When I release the lever they go out? Any wisdom for this, could it be the regulator?

Sorry, not a wiz at electrical by any means! When you say check the grounds, how do I do that?

Check your GREEN WIRES those are GROUND WIRES usually what they do is they solder a bunch together and then go to the frame with one to ground all of them. So check where your NEGATIVE post on the battery goes to and also the ground wire from the motor to frame they usually put the grounds all on the same place on the frame. It could also just be a GREEN WIRE came off a plug and is disconnected.
Or you can get a multi meter and test for CONTINUITY on all the green wires to find the one that is not grounded.

I checked every green wire for continuity and every one beeped from the engine ground and frame ground. Checked engine to frame and battery, good. The only one I couldn't check is the rear brake lever start/stop switch to the connector at the upper wire harness because it is sealed.

Well what can I say but there is one that is not grounded and its a main one for the rest of the system. Have you checked the green wire from the R/R also the one from the stator? Did you change the battery or take it out or anything some have a green wire hooked up to the negative and maybe it is not making good contact.

I agree this is a ground issue

there is a large plug below the handlebars from the main harness. The handlebar side has one green wire going up and all the other greens connect to it. I bet it pulled back, when you turn the signals on do you hear a buzz?

No buzz from turn signals. Here is what I have observed; when I start the scoot, everything works, but after a few minutes the lights start to dim. As soon as I use the rear brake lever the lights brighten, but as soon as I let go they dim again and even if I drive or rev the motor they only brighten when I use the brake lever. Like I said earlier, I get continuity through all the ground wires from the upper wire harness through to the lower wire harness. Could there be a short in the brake lever switch? I haven't replaced the regulator/rectifier, could it be that?

Get a multi meter, start the scoot and check the battery and see what the voltage is then rev it up and see if the voltage goes up to at least 13+ Volts.
Did you check the green ground wire on the R/R . Now since you swapped motors Was the PLUG from the new motor to the R/R the SAME and I mean the same color wires in the same location as the old stator plug. You may need a different R/r FOR THAT MOTOR.

Ok, here is what I did Sunday; I checked the charge on the battery while reving the motor, went up to 14.9 but never over. Checked the green wire from the R/R and got continuity. I Checked the R/R and the new one that came with the motor is a 5 pin female while the one on the scoot is a 4 pin male.

What!! so how many wires are coming from the STATOR that go to the plug and what are the colors.
4 and 5 do not jive so you re-wired something?

There is a yellow, green, and white wire from the stator to a 4 pin connector. There is also a black wire with a red strip and a blue wire with a white strip in single bullet connectors. The R/R on my scoot has just a connector on it but the connector that plugs into it has a red, yellow, white, and green wire.

1. The BLACK/RED Wire (is the POWER wire for the CDI) it goes to the BOTTOM of the TWO plug on the CDI.
2. The BLUE/WHITE Wire (is the PICKUP Coil wire for the CDI) it goes to the TOP LEFT of the 4 PLUG on the CDI that is the Trigger Wire tells the CDI when to release the voltage to the COIL to fire the plug.
The RED on the R/R is output to the Battery to charge it. So the YELLOW/GREEN/WHITE should match up from the STATOR and R/R .
