About Course
Welcome to the ‘Diagnosing Voltage Drops and High Resistance Problems Course!
In this course, you will learn how to identify high resistance problems and unwanted voltage drop issues that can develop in automotive vehicles. High resistance robs some of the voltage that a circuit needs to operate properly. If the voltage drop caused by high resistance is severe enough, the circuit may not work at all.
Basic electrical diagnostic principles are reviewed so you can confidently understand how to interpret the voltage readings when you make them as part of your electrical diagnosis.
The key to successful diagnosis comes down to answering three questions.
1) What voltage do I expect?
2) What voltage do I measure?
3) What does it mean?
This course includes demonstration videos and case studies to help you see why specific measurements are made and how the results of these measurements allow you to narrow down, and pinpoint where a fault is located.
Ground side and power side voltage drop are explained and demonstrated, and the understanding you need is provided so you will not be fooled by these challenging issues.
Also discussed are safety and maintenance considerations to help keep you and the vehicles you service out of trouble.
Collectively, the information provided in this course will be a welcome addition to your mental toolbox and save you time and headaches that can occur from strange and intermittent electrical problems.
