When checking a live circuit with an open, you will read full battery voltage up to the point of the break. Immediately after the break, the voltage will drop to zero. 2. Short Circuits
When technicians search for resources like the foundational concepts found in Dan Sullivan's electrical troubleshooting guides, they are looking for clear rules to conquer complex schematics. This article breaks down the core principles of fundamental electrical troubleshooting, focusing on the highly effective "Sullivan-style" approach to diagnosing DC circuits, using digital multimeters (DMMs), and mastering the logic of voltage drops. 1.
