**课程名称：** 诊断电压降和高电阻问题 **课程概述：** 本课程将教授如何在汽车中识别高电阻问题和不必要的电压降。高电阻会削弱电路正常运行所需的电压，严重时甚至会导致 circuits 无法工作。课程将回顾基本的电气诊断原理，帮助您自信地解读电压读数。成功的诊断关键在于回答三个问题： 1. 我预期的电压是多少？ 2. 我测得的电压是多少？ 3. 这意味着什么？ 课程包含演示视频和案例研究，帮助您理解特定测量值为何重要，以及测量结果如何帮助您缩小故障范围并准确定位。课程将解释和演示搭铁侧和电源侧的电压降，并提供必要的理解，让您能应对这些棘手的电气问题。此外，课程还将讨论安全及维护注意事项。 本课程提供的信息将是您诊断工具箱的宝贵补充，帮助您节省时间，避免因奇怪或间歇性的电气问题带来的困扰。 **课程大纲：** 无
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.Let's get started!
