10 Years later: The Trainer #47: What measuring voltage on the ground side means
October 29, 2025, marks the 10th anniversary of the most popular video on the Vehicle Service & Repair Video Network. With over 2 million views and 116,000 hours of watch time, the video is still as relevant today as the day it was released.
In this video, Pete Meier breaks down the importance of loaded circuit testing and testing that circuit for “voltage thieves" on both the power and ground sides of the circuit. Meier takes the lessons he learned from his long career as a technician and breaks them down into concepts that are easily understood by technicians at all levels.
Watch the full video and learn for yourself why Meier says, “It begins with understanding some basic rules on how electrons act, what causes them to act the way they do."
