How to Use a Multimeter to Check for Car Electrical Leakage?

[LaBryce]

Methods for using a multimeter to check for car electrical leakage: 1. Set the multimeter to the correct range. The multimeter has ranges for measuring voltage, resistance, and current. To measure car electrical leakage, rotate the knob to the current measurement range. 2. Select the appropriate range. For most cars, the 20A range is selected, and then insert the red probe into the socket labeled 20A. 3. After adjusting the multimeter, turn off the car engine, shut down all electrical devices, and lock the doors. 4. Open the hood, disconnect the negative terminal of the battery, connect the red probe of the multimeter to the car body ground wire, and connect the black probe to the negative terminal of the battery. Observe the current displayed on the multimeter. The multimeter is one of the commonly used instruments for detecting electronic circuits, with the main advantages of being portable, easy to use, and capable of measuring multiple parameters significantly.
