This video covers the essential steps to properly test a car's alternator and diagnose common alternator issues. The guide demonstrates how to check the voltage regulator, diode rectifier, stator, and ...

2. Test Leads Before testing the circuit, connect the leads together. There will always be some resistance present due to the leads, and your multimeter will give a reading of how much.

For automotive circuits, we recommend an auto-ranging meter with at least 20MΩ of internal resistance. Make sure to use the correct multimeter setting for a car battery.

A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

How do you know if a resistor is correctly restricting the flow of electricity? Using a multimeter is an obvious answer. However, there is more to it than meets the eye. This article will explain ...
