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.
The objective of the Leakage Current test is to verify that the electrical insulation used to protect the user from a Risk of Shock is suitable for the application. Leakage Current testing is used to verify that the product does not leak excessive current when contacted by the user. For medical equipment, the current flowing to ground is measured.
With leakage current, you want to measure the current. If voltage can be compared with the measurement of the width of a classic plumbing pipe, indicating how much water can flow through it at any time, the current would be a measurement of how much water actually flows through.
Again, we want the electricity to stay inside the circuit, and inside the insulation, too. A lot of measurements you do with your multimeter are voltage measurements. Voltage is the total capacity of a circuit or electrical component. With leakage current, you want to measure the current.
You can only measure the characteristic leakage at 60 Hz by using a clamp meter that incorporates a narrow band-pass filter for removing currents at other frequencies. When the load is connected (switched on), the leakage current measured includes leakage in load equipment.
Meter particularly designed for determining leakage currents is utilised. The current streaming through the ground rod is quantified by attaching the meter in series with the earthing connection. The ground connection is unsealed and the current streaming to the neutral side of the power line is measured, for data processing equipment.
