Part 3/8:

The owner of the electric bicycle reported that the potentiometer was no longer functioning, leading to a call for assistance in repairing it. A thorough examination confirmed that the potentiometer was indeed unresponsive; it was supposed to provide a resistance of 5k ohms, but instead was registering nearly infinite resistance.

Disassembling the Potentiometer

To begin resolving the issue, the first step was to dismantle the potentiometer. A motor was attached to the potentiometer via gears, allowing for precise control over its rotation. However, since the potentiometer was not responding, the investigation directed attention to its mechanical components.
