Ok got a Kymco Engine was torn up. Replaced with a generic gy6 150 engine. So I went to start it up and boom worked like a charm. However minutes later i blew both my front and back lights as well as dash ones. Went to get another regulator from a guy and he told me some put out more current than others which explains why it happened however, now the regulator isnt charging my battery. I tested a few wires coming off the stator (by now everything on the bike is gy6 down to the cdi)
Yellow line coming off the stator is about 20volts at idle
White is Around 6 volts at idle
both will raise up to around 40-50 if i rev it some. I get these same readings at the Regulator but no change in DC voltage.
I checked the ground wire coming from regulator and It had continuity with ground.
The actual regulator doesn't have to be bolted to the frame to work correct?
I tried with and without with no change.
Also might I note that the yellow wire the ran back to the tail light was making continuity with ground so I by passed that and still no luck.
Finally I turned on the bike than unplugged the wire going from the battery to the R/R Its only ready .5 volts however it will raise up linearly to 1.5 to 2 volts. Does this mean my stator is bad? My lights will turn on fine. (I dont leave them on long because they may blow again)

Check the fuse on the thin red wire coming off the battery, it may be to big it should be 10a fuse, you may also have a bad ground.

So first things first I started getting 19volt readings from my multi-meter. Changed the batteries on that bad boy real quick. Now through some stroke of luck I have unhooked the hot wire going from R/R to battery and now reads 6 volts dc at idle all the way up to around 13.9 volts dc at high RPMS! =)
But when I go to reattach this line to my battery it never reads higher voltages even at almost WOT it sits at around 12.6 or so. Is my battery just trash?

WHAT!! not possible BRO, if you unhooked the wire from the R/R that charges your battery NO WAY IN will the voltage read 13.9 volts off the battery THERE IS NOTHING charging it. Or am getting what you did wrong?
OR IS THIS what you mean, checked the wire right at the R/R and it read 12.6 at IDLE and at higher RPMS it goes up 13+ volts. IF so then the R/R is good and your battery is shot.

Not exactly. I unplugged the wire that leads to the regulator from the battery at the battery. The wire is still connected to the RR. So i test the battery without it and its reading 12.6 with no change at high rpms because its not attached to RR. Then I read voltage coming from RR it sits at 6 volts at idle and gets up to 13 some odd volts at higher rpms. However if i connect RR to battery it reads 12.6 even at higher rpms.
If the battery is shot shouldnt I be able to hook a regular battery charger to it and see no net change just as the RR had no net change on it?

To find out if its the battery that is not taking a charge do this, connect the R/R to the battery start it up and then TEST the wire from the R/R if it is putting out 13+ to the battery but the battery then if you switch and test the battery and it still shows 12.6 then its your battery that is not taking a charge, either that or you have a bad draw someplace that is sucking the battery.
Another means of telling if the battery is shot is see what the volts drop to when starting it.

can we see your regulator ?

Ok when I connect a regular battery charger to it as soon as both leads touch the battery theres a noticeable jump in voltage coming from the battery. Also It was just sitting at about 12.18 volts and dropped to about 12.08 after turning it on. I've tried regrounding the RR to see if thats the issue but still no luck. I even tried a different RR same issue. I get voltage coming from the RR when wire is disconnected from battery to RR. But as soon as I touch it to RR all im getting is constant battery voltage with no change at higher rpms.

I think you need to take your battery out of the scooter and put it on a slow charge 1.5-2amp slow charge , let it run through its cycle . check the voltage on the battery then let it sit for a few hours and see what it drops to . If the regulator is giving good voltage disconnected from the battery then it looks like it could be a bad battery .
I would be interested in what the load is , have you added any lights , changed to led's , put in a larger wattage headlight bulb . If you changed the load was it on the ac or dc side ?

So the problem was the RR I found another out of pure luck (after ordering new ones) and tried and she she charges up just fine. ( I think the grounding pin had burned out which was why it was reading 13 volts but not sending the 13 volts to the battery when hooked up) To keep from blowing my lights again I just wired the to my battery with an on off switch. I still cannot figure out why its putting out so much current.
