80V BLDC Controller Repair

In this video we repair a SNR8503M Brushless DC motor controller. These are cheap, but also take a while to get. That is why I am taking time to repair this one in this video. It will help with a project I am currently working on while I have another one on order. We also learn a lot more about a board while working on it and testing. I will also share the manual for these cheap controllers that some may find helpful. You can also find it as a pdf file on our FB page called On The Bench. I hope you find the video helpful and thanks for watching.
