I purchased your item 2001708003 Brushless Sensored Motor Controller but it didn’t come with any documentation or support manual. Can you please send supporting documentation that will help us use this product.
Printed on the back of the meter, there is an item shown just to the left of the shunt (connected to V+ line)? It has text in Chinese, but I don’t read Chinese. I have the meter connected where it displays the voltage correctly, but the amperage remains at zero regardless of the attached load.
