Help, have to confess I completely stuck. I got a Chinese controller 1800 w 48v with motor to do a kids quad conversion and nothing seems to be working. It also doesn't help that the controller came with no instructions and I'm trying to work off a screenshot provided by the seller that's all in Chinese.

I definitely need someone, smarter than myself, to tell me what connections are for what. I know obviously the power, phase and Hall line are connected correctly but I cannot figure out where the throttle should be connected as well as things like for example the break as nothing is labeled and multiple connections could work. Attaching images, hoping someone is familiar enough to tell me what to do.

Lets see if we can figure it out

...according to your diagram

1. should be your (2) power wires (thick) red 48V(+) & black (-) negative

...connect them to the battery pack


2. should be your (3) phase wires (thick) blue, green & yellow

...connect them to the motor


3. should be your (5) hall wires

...connect them to the motor too


4. should be your (2) controller wires for an (on/off) switch

...connect them with/to a toggle switch


5. should be your (3) throttle input wires

...connect them to your throttle (1. yellow (signal) 2. red (power) 3. black (negative)
* (be sure the red & black wires align on your throttle & controller plugs, the signal wires may be different colors)

6. ** NOT sure what this is or for

7. I believe is your forward & reverse wires (motor will NOT work if nothing is attached to this plug) (doesn't know if you want to go forward or backward)

...connect with an (on/on) switch

A lot of guesses & I am NOT sure about the rest

...but, they shouldn't be needed (or connected) just to operate
the motor (for accessories like brake light, charging port etc.)


* idea - to be sure

...put a translator app on your phone

...take a pic of each symbol

...ask it to translate it into English

Thanks. Port 5's yellow wire taps over to port 6... I don't know what it should connect to from that point.

5, 6 and 7 pictured here, they seem to interconnect.

The orange wire on 7 is 48v

Tried the conversion apps... Seems they can't translate it right. The throttle, gear and break all seem to be missing

I came across another diagram

...it may be helpful to cross reference


It looks like

P+ is battery pack voltage, positive (+) (thick) red wire, power in

in side it should connect to

...the charge port

...& (supplies power to) the "power lock" (on/off switch)


P- is battery pack, negative (-) (thick) black wire, negative in

inside it should connect to

...the charge port

...& supplies the ground connection



Pretty sure,

...(4) is your "power lock" (on/off switch)

because, it's labeled VCC & P+

...(8) should be your throttle plug (NOT (5) like I thought earlier)

because, it's labeled 4.3V (throttle reference voltage) & (SD) & (GRD)

Hope it helps :D

Thanks! This one cleared up a lot! And it makes sense too! The designation on the page helps.

All I need to figure out is where the gear is now. Tried a few ports, with no go yet. I think that 5/6/7 or the last port have something to do with it

Question... In your setup, what voltage do you get from the inverted gear connections

Did you get this going?

I recently found this:

Wires Interface Definition:
Power Cables: Thick Black (Power Negative) / Thick Red (Power Positive)
Charge Port: Thin Red (Power Positive) / Thin Black (Power Negative)
Phase Cables: Thick Yellow + Thick Green + Thick Blue
Electric Door Lock Cable: Orange VCC, Red P+
Hall Cables: Thin Red, Thin Black, Thin Yellow, Thin Green, Thin Blue
Commutator: Black (GND), Purple, Orange (VCC)
Speed Cables: Orange (High Speed) + Black (GND) + Blue (Low Speed)
Speed Limit: Grey (GND), Grey (XS)
Anti-theft Cables: Red(Positive) + Black (GND)

So, it looks like the "gear" plug would be the
..."speed cables" (orange-high speed) + black ( low-speed)

Yeah, though I ended up getting a new controller and throttle. I think the old controller had a short in it that burned out the throttles I was testing with. talk about a major pain in the rear end with these issues. I still have the old controller, I may try to mess around with it 2 track where the short is when I have time

I am glad you got it going. :D

There are a few others who bought this motor & controller & are still having problems :eek:

Could you post or list exactly what you connected?
...which plugs you connected
...& where you connected them
...or what type of switches you used

It would be most helpful :cool:

Will do! In the mean time, here is some eye candy prep work!

After all the futzing around, I realized I made a big good. The kids quad has a #420 chain on it, I thought it was a #35... So here I am with a #35 setup and can't connect it to the axle rear sprocket... Big goof on my side for sure.

Them little details
...make a big difference

Here is a drive sprocket for 420 chain
https://www.ebay.com/itm/420-Sprock...shaft-axle-minibike-gokart-quad-/152838338269

...just make sure it has the right center bore, to match your motor
unfortunately it's 11.8 mm, when the shaft of the MY1020 is 10MM... searced pretty hard for one, looks like my only option is a jackshaft to convert it from a #35 to a #420.

I am actually quite surprised how few attachments i could find for a 10MM shaft...
