When these things go bad, look out! All of my lights were burned out on my Tao Tao and the gas gauge quit. Thanks for the video. Short and to the point.

When I was a kid, the cooling fins on the reg/rec made me think it was a tiny internal combustion engine itself! You live and learn. :)

So I have a 49cc scooter. I wanted to know if you provide the full wire harness kits with stator and all of the other wiring components. I saw a lot of packages on google, but I would like to help support you if possible. I have 3 scooters I am repairing. 1 is a Buddy 50. Are you able to provide the prices for me? If so... How do I contact you?

Hell yeah bro you just told me what my problem was. Every time i hit half throttle im reading 16an a half volts and my light bulbs are exploding

Jim, Good question. We have gone through tons of off brand chinese big bore kits. We use off brand chinese kits too. But I will say we went through about 15 different manufactures before we found the right kit that didn't have issues or were missing parts. We sale both chinese kits ($150) and fancy ncy kits ($300). The truth is you pay for what you get. Our $150 kit is pieced together from a couple different manufactures. It is really risky buying a kit from a unknown dealer.Do your research.

my gy6 150cc when i start cold, i get bright head lights then after 10secs they become very dim, i installed a new stator with same affect, so it has to be my regulator?

I got a 50 cc scooter and when i got this bike the bike was completely dead and was wrecked from the front end my question is this rectifier regulator is it suppose to get very very hot to where you smell burnt plastic?? everytime i charge the battery and reinstall it that rectifier gets so hot it looks like its frying the plastic i took it off had to get a towel because something is not right if you can let me know i feel this device is not working right but please let me know and it drains the battery right away also.

Do you know that the wiring diagram is on the NCY Regulator/Rectifier?

my lights go dimmer at high rpm,so when i unplug the reg rec they go nice an bright but thing is its a new reg rec also battery isnt charging,any ideas?

Im looking for a price on building a Lance Cabo 50CC motor into the biggest I can get. I can supply the original motor, or get a case from you. I was looking over your site but I can't figure out what motor you already have that would work. I want it to be super fast. Thanks Ken

Please, I wonder if this regulator/rectifier will work on my Yamaha Axis 90cc, year 2002 model motor scooter?

Would it send more power through the bike if it is bad and make everything brighter

Good video..

It would be nice if you could show how to test the rectifier regulator to see if it’s good or bad. There must be a way to do a static test with a voltmeter.

How many amps can this rectifier/regulator handle at 100% load?

My taotao speed 50 headlight doesn't work (there is one main bulb and two led lights one on each side of the main headlight.) None of them work all my other lights are working i checked the bulbs and the wiring they seem to be okay for the most part. ( what are the chances that all three lights have faulty wiring) it used to come on and off randomly but now i can't get it to turn on at all. I need to pass inspection and it's also a hazard riding at night. Could this be my problem? I don't have a voltage reader and i'm a broke college kid so i can't take it to a mechanic and it's my daily commuter. Running out of options. Considered wiring main headlight directly to the battery with a toggle switch but i'm also running an alarm off the battery so I don't know if that's a good idea. Please give me some advice on what to do. Thank you in advance.

I just wanted to point out that the charging voltage of a lithium ion battery is higher than a lead acid battery. You can get up to 14.8v.

I´ve put my GY6 125cc scooter xenon lights,but the battery discharged ease as I resolve this?

Hey rollerwrench , so I have a 150cc my headlights stopped working except the signal lights idk what's wrong should I buy new voltage regulator?

i purchased this type of voltage regulator from ebay.My Bike is FZR 250 2kr.But my original voltage regulator have 6 wires.3 from stater.one red for battery terminal ,green wire for starter solenoid input and black wire for earth. But original voltage regulator also only 4 wire type.only thing i want to know which clip is red battery positive terminal connection.then i can connect other 3 wires to stater 3 wires.Thanks.

Hey bud let me ask you, I had a bad regulator because it was charging 15.1 volts. I had several new regulators but they were all 5 pin with an extra black wire. I know I shouldn't have but I cut the connector and hard wired everything to the new regulator except for the black wire because there was no black wire. Just a green red white and yellow. Surprisingly the voltage came down to 13 and my light worked which they didn't earlier with the bad regulator. What do I do with the black wire? I noticed my digital odometer and speedometer stopped working when I put the new regulator on. Maybe I should have connected the black wire with one of the other wires? Please help!

Great talk. could do with a drawing of the circuit.Thanks anyway!

How can I test it if it works ok or its faulty??

I have a gy6 engine on a kids side by side. I cannot figure the problem out. The ground wire on the plug arcs when I plug in a new voltage regualtor and the fuse blows. The old VR was burned so I assumed this was the problem. Unplugging the stator made the ground terminal not are when plugging in the VR. the side by side RN but battery would slowly die, obviously because stator was not supplying voltage. I replace the stator and i got the same thing.

How do find out the correct pin outs on the rectifier? We have tried two the Last one cooked a circuit?

Hey, great vid. I recently bought an ebay 4pin regulator/rectifier but after wiring it correctly, as you have illustrated, it is only producing between 2.5-4.2 volts. I hate electronics and am pulling my hair out trying to diagnose. Do you think it sounds like a stator problem or a dodgy regulator/rectifier?

You have made a very interesting video. I have watched many similar one's but nobody explains what the terminals are! i am trying to wire in a non-standard instalation and no one explains which terminals go to where. Except the red goes to battery, I think ground is through the body????? And the stator goes to somewhere? and there is still a terminal not explained????? Lots of video's on this rectifyer explaining NOTHING! Does anybody know how to actually wire it up from scratch?

so I just purchased a GY6 150 to swap my 50cc Out But my voltage regulator on my 50cc is a 4 pin like the one you have in your video the new one that came with my 150 cc is a lot bigger and is a 5 pin what do I do here is there another way that I have to wire this or I need some help here if anybody could give me some help that would be great.

Hey if I change that and the stator and it’s still not charging the battery what do I need to do cause I really don’t know to much on doing this but I have changed about 4 stators and still nothing what’s going on with it

Well brother I'm asking the authority on rectifiers I've heard all kinds of whatever you want to call it rhetoric about rectifiers does this actually give your coil more power to work with some people say yes some people have looked at me like I had three heads I know ncy supposed to put out one that Moore performance but I wanted to come to you to ask you first waving my hand from Gainesville Florida

Ok so I have same rectifier and upgraded to the performance ncy brand,it stated it would give 15% more power over stock kind. Now I have a volt meter on my scooter and it keeps a good 12 volts at idle to 13 but as soon as I start riding and I'm going fast itll go up right to 15.0 and I run leds not sure what's going on any help will appreciate

Can you explain the wiring diagram of this kind of rectifier

Will this work for a Honda scooter?

Will this work on a 250cc??

Will this cause a no spark? I have a 2002 kymco cobra with no spark I replaced the CDI Box Spark Plug Ignition coil and stator. Im thinking its kill switch when I try to crank it it will crank but it will also crank in the off position? Also my battery is very low from trying to crank I hear a click sound coming from the battery compartment but when I kick start it it charges the battery a little bit so it will crank with the electric start any advice?

The rectifier will not cause a no spark issue. Disconnect your right hand control and try to kick start it. This will eliminate the kill switch from the mix, or you can pull the kill wire from the stator or cdi box. Use my cdi video for that

On a regulator rectifier like that where there are no wires coming out of the unit, how do you tell which is the positive and negative terminals? I had to replace the connector on the wiring harness because the heat from the regulator rectifier fried the connector and wires. I spliced the connector off the bike and now I want to know which wire goes where (yeah, I know, I didn't mark them beforehand). So using a multi-meter how do I figure out the positive and negative on the rectifier?

Hold the rectifier with the tabs facing you and the base, or bottom, has the drilled holes for mounting. Our of your rectifier has heat fins, they're the top. Now looking at the tabs the bottom left is the hot, positive, or traditionally the solid red wire. The bottom right is your ground, or traditionally the solid black wire. The top two don't matter which of the remaining two you connect either of them to. In my case they were both white wires. I hope that helped. I already did mine and it works great. I know the wiring because I found online a color coded schematic.

Hi everyone, I need some help. I'm well versed in Cars: Trouble Shooting AND working on them myself. But this brand new lil ICE BEAR RETRO 49cc is a BIG problem. She's been in the Shop 6 times, SAME problem. She sputters, cuts off, hard to start, dies CONSTANTLY. I asked them to check: COIL, CARB, CDI, IGNITION WIRES, KILL SWITCH. They replaced everything. Now she starts up fine, has power while in motion, but DIES at Every stop sign, stop light, etc. She wont idle. I also noticed, in "idle", ALL LIGHTS are DIM. When I give her gas, All lights are EXTREMELY BRIGHT. I appreciate your help! X♡
