Out of ckt black. 0dcv red 0vdc white 12vdc at idle 14vdc reved
In ckt white reads 5vdc &ac black and red 14.3vdc revved or idle

A little confused? Born that way. LOL With the scooter revved you read 14Vdc on the white and was that with one lead of multimeter to ground and the other to the white lead?
Same with the red and black one lead to ground the other to each wire itself?
I expected 12Vdc + on both red and black wires, we know red goes to the battery to charge and the black goes to the igntion and is the sensor wire but if that white is actually 14Vdc revved then we got a winner to run the fan!
Please tell me this is so!
Going to take the family to the County Fair will check back in later.

I got 14vdc on the white , when the red white and black were not connected , the white red black are in the same plug . the only thing the white wire connects to is the enrichner .
I hope this helps if you need more readings let me know what you need .

That's what I expected from doing research on other people using this R/R. 5 to 6 volts DC at the white wire under load at normal operating speed. I would think the fan would be more of a load than the enricher so the output would probably drop more using the white wire to power the fan. There was AC mixed with the DC also? Not good for a DC motor.  Hope you guys had a good time at the County Fair, JR. |

Well did have a good time watching the grandkids riding all those crazy rides, not me though I wouldn't dare! But I did get some good funnel cake and a carmel apple!
Man that's disappointing and I agree Cruiser not enough for the fan IMO but it still doesn't make sense why they would do this again this is a 3 phase stator so why not bump up the voltage to a good 12 volts?
Ok TV I'll ask a couple more things GY-Rocket reported up to 16VDc revved on his scooter on the red wire.
Is your battery fully charged and when you say reveed are you talking about a minimum of at least 3000RPM? And was the 5Vdc on the white at idle or revved up?
Also you do have the red to the battery, black to the ignition and white only to the autochoke green to ground. This is the combination that he reported and his voltage varied from idle to higher RPM's.
I still say with a 16Vdc R/R one could run HID's with no issues?

JR , a light just went off , you talk about balancing or providing some ac load what about a capacitor and and bridge rectifier off the 3 yellows with a 16vdc zener diode , just to feed the HID . I will tell you I noticed my r/r was warmer than I care for however I had next to no load just ignition , the front fairing is off so no head lights connected .

TV you may be on to something there! We've got 3 phases and this was what my thought was on the 7-pin R/R that they were doing this already? But apparently not and also one would not need 16Vdc to run the fan or HID's but a steady 12Vdc+ would be find. On this scooter the fan draws a lot at right at 6 amps but some Like Damin and Cruiser have changed their fans to like on the linhai which only pulls 33 watts= 2.75 amps. And you're right with your front off and no lights the R/R is going to warm up it's shunting all that unused voltage to ground. So here's a thought? Why couldn't it be possible to run dual R/R's? Say like a 5-pin; cgi.ebay.com/ebaymotors/GY6-Scooter-ATV-Engine-150cc-5-PIN-RECTIFIER-REGULATOR-/220650051706?pt=Other_Vehicle_Parts&hash=item335fc4987aTie the yellow and white to two of the yellow wires from the stator, black to igntion red to the battery and green to ground. The a 4 pin R/R: cgi.ebay.com/ebaymotors/Voltage-Regulator-Rectifier-Honda-CG-Dirt-Bike-4-wires-/170573911412?pt=Motorcycles_Parts_Accessories&hash=item27b6ff5574Tie the yellow to the last yellow unused leg on the stator, white to the same white leg of the 5-pin R/R green to ground red to the new light circuit and what about the black? Could you tie it in with the same black igniton wire as the 5 pin if it is also just a voltage sensing wire? Leave it open? Or put a 13Vdc load resistor on it to similate 13Vdc load for the R/R which would be plenty to run the HID's or even the fan if you seperated it out from the other R/R? The reason I keep saying to seperate the fan as it doesn't need voltage if it's cool enough and not running. Would this not be close to the same as tapping one of the yellow legs which I think would work too? If you could run two R/R's then for sure you would have two seperate 12Vdc+ charging circuits. JR |

Ya know JR an increase in voltage reduces the current/amps . I think that is what your doing with your 16vdc on your scooter . Do you have HID ? Just another thought the wired going to the CDI is 115vac when cranking , I wonder what it is reved up , refigeration blower motor only pulls about 1-2amps at 115vac . Is there a horse power rating on a cooling fan on a scooter ? I think I will go take a reading on the cdi voltage from the stator .

gee thats funny about 55vac and on decell about 75vac , no load cranking 115vac ? interesting .

Is there a horse power rating on a cooling fan on a scooter ? I think I will go take a reading on the cdi voltage from the stator . John Good question? No I don't run HID's on my linhai as like I've said I rarely ride at tnight and if i do it's very short distances and not having to like some may have to on a scooter. I did put a pretty good digiatal volt meter on my scooter as the reflex clone with the linhai doesn't have one but as I've said before there have been numerous people put dual bulb HID's on the linahi version with successs and not battery problems and IMO it stemms from these things: (1) The cooling fan on the linhai is 33 watts =2.75 amps while the CfMoto clone has a fan rated in the 6 amp range double the amp load (2) The linhai cooling system has a better desiign which allows the fan not to run near as much in all weather example from what I've always read the CfMoto version will cycle on and off even say on a 80 degree day while if I'm riding down the raod on my linhai version at 80F the fan will never come on. (3) While I have no proven specs on this I believe the linhai stator and R/R are rated higher than the Moto version. Now like most people I have converted my linhai version to all LED's which we know puts more charging amps back into the system. I also believe a higher rated AH/CCA battery will keep the system stronger thus giving more of the charging to a HID system versus putting it all on just keeping the battery charged. I use a jet ski battery in my scooter which fits the OEM box and is rated at 14ah/210CCA the OEM one was at no more than 7ah. The CDI accepts the voltage coming from the stator and stored it in a capacitor. It also has a diode in the CDI which converts the AC voltage it receives to DC voltage which goes out to the secondary coil (coil with the plug wires on them). SO the CDI accepts the AC voltage, it releases the stepped up DC voltage when the trigger tells it to start the spark and it controls the duration of the spark. Of course at higher RPMS you're talking about things working in fractions of a second. Basically the CDI acts like the old points and condensor...it stores energy, increases it by using the capacitor, releases the energy and controls how long it outputs the energy. Basically the CDI controls your timing at varying RPMS. So the AC voltage on the CDI is lower when it's running? |

Okay. This is so confusing. I will be the guinea pig and buy one of those 7 wire R/R from scrappy if they put one cheap R/R back to list on ebay. I asked if they still have those and they answered "yes". I asked them to list one of them to ebay and then I will buy one.
Because of I live in another side of earth it will take 2-4 weeks when package arrives. But first they have to list it back to ebay.
Then I will check the voltages of every coloured wire.

Man I can't wait to see what it'll do with a 18 coil stator and my thought is the worst that can happen is it's no better and you can keep it for a spare because I see no reason it still won't work as well as a 6 pin R/R?
We'll bewaitimng.

They are the same both have the same colors.
