In this video, Kent starts out by talking about equipment and supplies and then proceeds to use an old floor lamp to demonstrate the volt-ohm meter and explain two key things to remember when troubleshooting any type of electrical problem. In the second part of the video, Kent shows you additional test equipment you might want to have on hand when you get serious about working on your own car. Remember, this equipment does not have to be expensive. Along with a volt-ohm meter, you will also need a 12-volt power source when testing electrical components and he explains two different options.
There are four types of electrical tests you can use when diagnosing a specific problem. Kent demonstrates each test in detail and shows you how to use the appropriate tester to perform each one. He shows an example to review what you have learned by troubleshooting a power window problem in a W126 sedan. Towards the end, he even throws in a little "quiz" asking how you would go about testing an electric auxiliary fan. In conclusion, he shares a story of a friend who spent a bunch of time and money trying to fix a tail light problem in a W123 240D. He did it by "throwing parts" at the problem BEFORE doing a proper electric system diagnosis. Don't let that happen to you!
