How to Measure Car Leakage with a Multimeter?

[Ryder]

To measure car leakage with a multimeter, follow these steps: 1. Select the correct range. The multimeter has ranges for measuring voltage, resistance, and current. To measure car leakage, set the multimeter to the current measurement range. 2. Choose the appropriate range. When measuring current, select the range from large to small. A range that is too small may damage the multimeter, so choose the correct range from large to small. 3. Open the hood of the vehicle to be tested, turn off all electrical devices, and lock the doors. For vehicles with remote controls, use the remote to lock the car. 4. Use the appropriate wrench to remove the negative terminal of the battery. Connect the red probe of the multimeter to the vehicle's grounding wire and the black probe to the negative terminal of the battery. 5. After completing the operation, wait for 30 seconds and read the value on the multimeter to determine if there is a leakage fault in the car.
