Y uandai Intelligent Brushless Controller 48V 60V 72V 84V 2000W

How can I test my controller to see if it’s not working I got it all plugged up and it won’t work I get the correct voltage when I test everything and my throttle works

How can you test it? You hook the motor up and see if it spins. Did you follow their guide? This is not a video, but is a screen cap.




This is a learning controller. Did you do the learning sequence first?

 

[Taitertot]

Yes I did the intelligent recognition and still nothing and I’m only getting 3.2 volts off the throttle not 4.8

my throttle works

I’m only getting 3.2 volts off the throttle not 4.8

Both of these can't be true, if your throttle is supposed to output 4.8v according to it's documentation.

If it is only supposed to output 3.2v (at max throttle) then it is working correctly.

To know which is true, you'd have to check it's documentation (if there is any, very rare) to find out it's normal operational outputs.


By "got it all plugged up", what specificaly and exactly do you mean?

What is your exact wiring setup, wire by wire, from it to everything else? Post an image of your drawing of the wiring you have actually connected (not whatever diagrams you have that tell you how to connect it, but how you actually have verified wire by wire that it is really connected--it's very common to have differences between these that make it not work).

What exact parts do you have connected? Links to the actual pages you purchased each one from will help us help you.

What voltage is your battery at? (measured, not just what it is supposed to be)

So the motor did spin when you connected the learning wires? Then you disconnected them.

I’ve been using this controller for a few months now, but the other day, one of my phase wires coming out of the motor broke so I had to re-solder it and when I connected the controller back up now I’m not getting no movement at all with plugging in the learning wires or with using the throttle

Readings voltage from 220uf/25 is 10.3 as78l05 input voltage 10.3 output voltage 2.7 220uf/16 2.7 voltage

DId the phase wire just fall out, or did it melt off? If there's a possibility it touched another phase or some of the hall sensors wires, you might be checking Hall sensor operation as well as the derive circuits, If this is new to you, there should be some info on Grins info pages at ebikes.ca.
