How to wire a GY6 scooter regulator / rectifier and how it all works (Part 3 the regulator)

Okay, here we test all the voltages with the bike running, and with the bike switched off, this should help you make sure your regulator is properly hooked up, and also properly wired (if this doesn't answer your questions, let me know and I'll do an even more indepth set of videos). But this should cover everything.

Hello...a little off topic, but I was looking at the city scene in the background, and it looks very nice...clean, palm trees, fairly quiet...what city is that? Thanks much!

@firemanntomm It's Shenzhen in Southern China (right next to Hong Kong) :)

hello there, I like the way you have wired you regualtor, I have a blown regulator due to me jump starting it with my wifes car resulting in my scoot blowning fuses even with out the ignition on. anyway I am having a hell of a time trying to get a replacement, would any 5 wire regulator work, if so how would I know what wires would connect where on the new reg?

@pet6171 it should work, I'll try and find a 5 wire to hook up to my gy6 here and test it out

[bigwill19591]

can you use a 5pin regulator in the place of a 4pin regulator,and how you do it

[serpentza]

@bigwill19591 I'm sure you can, I don't have one lying around to try :P

@islandminisunlimited Also the final wire may be the magnetic field supply for the alternator. Without this connected you will get zero AC when revving. This only applies if you have a field powered alternator. If you have a fixed magnet powered altternator then it will supply power even if that wire is not present.

Heres how it works. Red is 12 volt for charge. Test the alternator in AC only mode and rev the bike. It will go up in volts dramatically and drop when not revved. This will be on two wires going into the regulator - dont test by going AC wires to earth as this dumps the power from the alternator to your chassis. Test across say the white and green or the other. The final wire is probably a sense tester and isnt needed. I imagine the regulator is neagtive earthed so yes the red + and the metal -.

Hi, I did a test on my regulator and the reading are different i have on my red wire 14.8 DC Volts on my yellow 13.00/14.00 DC Volts, white 24.00/26.00 DC Volts and on the green -0.0034 DC Volts this is with the scooter on. Does this mean i have a blown Regulator? Cause i have completely no electrical power on my scooter no lights, brake light, horn and gages. Please help me

you haven't a clue ha ha

[MrJayVal]

hi, where is the yellow wire connected? and why is that everytime i turn on the headlight, my engine stops and when i rev it, the muffler blows? what do you think is the problem?

[londonTown1989]

hi, im not sure if im having a problem with my regualtor but i changed my front light on my bike, started it up and now i have no lights indicators and brake light work fine, no front or back light or horn, i have checked all the wires everything ok,ever tryed the old light and still nothing, allso now when i start the bike it just idles and backfires, do u think it could be the regulators gone
