How to Measure Vehicle Current Leakage with a Multimeter?

[BlakelyMarie]

Using a multimeter to measure vehicle current leakage involves the following steps: 1. Set the multimeter to the correct range. Multimeters have settings for measuring voltage, resistance, and current. To measure car current leakage, rotate the knob to the current measurement setting. 2. Select the measurement range. For most vehicles, the 20A range is appropriate. Then insert the red probe into the socket marked 20A. 3. After adjusting the multimeter, turn off the vehicle's engine, shut down all electrical devices, and lock the doors. 4. Open the hood, disconnect the negative terminal of the battery, connect the multimeter's red probe to the vehicle's grounding wire, and connect the black probe to the negative terminal of the battery. Observe the current displayed on the multimeter.
