To measure leakage current in the car, switch your multimeter to measure DC current, put the leads in the right portals, and put one lead on the negative terminal of the car battery and the other lead on different wires. When you find a big difference in the readings, you found a leakage current, which should be fixed.
Insert the multimeter connector into the corresponding terminal for measuring AC, then use one pen to measure the zero line or ground wire, and the other pen to measure the place where leakage is suspected, and look at the value displayed on the multimeter. If it is 0, it means no leakage and no voltage. .
