It's a 4 pin regulator. Red, White (pink for me), Yellow, and green. Although it could be a bad regulator because when I tried to test it according to this chart i943.photobucket.com/albums/ad271/imageshare/GY6voltageregulatorresistancechart.jpgand none of the resistances were right. Also the RPMs did not change the rate at which the red wire coming off of the regulator changed, it stayed about 12.7 all the time. |

I did a little bit more testing and here are my results. I checked the regulator and it was turning out 12.7v when the bike was on, this is on the low side but it will still charge. There are other values from the regulator but they all seemed reasonable from what I've read. The big problem seemed to be that my headlamps are wired into my DC circuit and when I unplugged them my battery jumped from 10.5v when it was on to 12v. So I am gonna have to find a wiring diagram and reroute the headlamps into the ac circuit if that is even possible. They draw quite a bit of current, so that might be the problem. I think my scoot is identical to yours, only older. Hopefully, my wiring is the same as yours. My headlights, front running lights and taillight all run off AC. Stoplight and turn signals run off DC. In fact, I'm working on a LED headlight setup, and using a "bridge-rectifier" on the high-beam to provide DC current for the LED, on high. LED's will run off AC, but like DC much better... LOL!As terrible as the "manual" is, the wiring diagram seems to be correct. If your manual has the diagram, you can trace the headlight wiring by wire color and see where they are hooked up, possibly incorrectly. If in doubt, I can check the wiring diagram on mine, and have you compare it with yours. Your incandescent headlights and taillight will run fine on AC. See if you have a wire diagram in your manual, and follow your hot wire back from the "dip-switch" and see if it's hooked up to AC or DC. Any help I can be, I'll be glad to offer. The wiring diagram on mine seems to be correct so far... See what you can find out. We'll all be watching your post to offer help. Sincerely, Leo PS: My "manual" shows TWO wiring diagrams. One for "Always Lighted Headlight" and one general diagram. While mine has the ALWAYS LIGHTED HEADLIGHT... that diagram is wrong. My wiring matches the general schematic. AND, you may need a magnifying glass to read the 3-point type! |

I'm gonna use www.chinesescooterreference.com/pdf/Wiring_diagram_colored.pdf as a guide to try and help me figure out where my power sources are. Some of the colors are mixed up but thats nothing I can't figure out. It seems that "Light Switch" is what my kill switch is, but I'll have to take another look at it to be sure. From the diagram it seems like yellow is the AC source that I'm gonna be looking to wire into for my headlamps. I'll definitely keep looking around and test some more tonight. |

Having charging issues also. This is driving me nuts! I replaced the regulator and the stator. I'm getting 38 volts ac on the yellow wire out of the voltage regulator.
Any suggestions?

Unfortunately it seems as if my LED headlights won't function off of ac and they burned out. So I am at a completely loss as to what I should try and do next. I also got an exhaust system which won't fit without a decent amount of modification so that's fun. Any hints on what I should be looking at in my electric circuit in order to keep my battery charged?

0.9Mohms isn't infinite or open.
I'll try to remember to check - I have two 4pin regulators. I do not know the values on either one.
I see crashguy measured 38VAC on the yellow fire from the stator. What is the value of the red wire from the regulator - can you measure with it disconnected from the battery?
I have to check my charging system a little more. I am up to 13.7VDC, but probably could be even another volt higher.
tvnacman has a lot of charging system knowledge.

My most recent round of testing is as follows. Resistances for my rectifier in similar to the chart I have posted before.
+ W Y R G
-
W \ ∞ ∞ ∞
Y ∞ \ ∞ .934M
R 300k ∞ \ ∞
G ∞ 1.05M ∞ \
I also have ~25v on my yellow AC (3v DC), 29V on my Red AC (12.6DC), 0/0 on Green, 25 White AC (3v DC).
Would it be wise to just buy a new Reg/rec and try that?

To come back and update this, It seems as if the regulator was the problem. I added a new one to my bike and now the voltage stays at 12.8 with the lights on, which is a significant improvement over the 10.5 it used to be at.
I unfortunately got an unsupported exhaust system, when I contacted the vendor they assured me that it would fit. So I am going to go to a local muffler shop and see if they can bend the header to make it fit.
Other than that the next things on my list of tweaks involve getting 16" tires for winter and adjusting the intake and exhaust valves.

My exhaust - they were sure it would not fit. I was sure Id have to cut and weld or open the flange r whatever to make it fit, but I only had to make the support to secure it to the swing arm, and mad a dent in the side so it isn't against the shock and axle.

[replyingto=elw]elw[/replyingto]yes. I did make a couple spacers. And a dent in the side.
I have pics on my photobucket.com. url in my signiture
