What is the normal leakage current in milliamperes for a car?
1 Answers
The normal value for car leakage current is generally around 40 milliamperes. Causes of car leakage: battery drain due to unswitched electrical appliances when parking, self-discharge and power loss caused by short circuit or oxidation shedding of battery plates. Leakage caused by grounding of automotive electrical appliances, wiring harnesses, sensors, controllers, actuators and other electronic components and circuits. Methods to find car leakage: check whether the battery voltage and power generation are normal and whether the battery terminals are severely rusted. If the static current is too large, it can be checked by pulling out fuses and relays one by one and observing the change in static current.
