How to spot a fault in a circuit, like a pro : hands on electronics [1]

In this video I show the method to find out a fault on an electronic circuit board. In the specific case we have an ESC (Electronic Speed Control) that is used to control a washing machine motor (used to drive the spindle of a lathe) and somewhere in the circuit there is a faulty contact. It turns out it was a bad soldering that caused an uncertain contact, making the motor to start and stop randomly. The video shows the procedure to spot the exact point where the fault is present. Wonder how to #faultfinding without schematic? Watch this video too: https://youtu.be/yjxuMwLN7zI For more related/complementary content over my videos please visit my website accidentalscience.com.
