Problem with your car, van, truck, motorcycle, or boat draining your battery over night or over a short period of time(known as parasitic drain) with little. It is called a parasitic draw because it continues to drain power from the vehicle’s battery, even though the vehicle is not in use. this can be caused by various electrical components that continue to draw power even when the vehicle is turned off, such as the radio, clock, or power windows. it could also be caused by:.

Parasitic drain is a condition where your vehicle’s battery drains even when the engine is off. causes include electronics left on, faulty wiring, malfunctioning alternators, old batteries, or infrequent use of the vehicle. fixing a parasitic drain usually costs up to $200, but it depends on the severity of the issue. 1. unplug all devices from your vehicle and make sure no electrical components are on. turn off the radio, heat or a c, lights, windshield wipers, etc. and close your glovebox and lighted mirror covers. engage the emergency brake, turn your vehicle off, and remove the key from the ignition if you haven't already.

Touch a lead to the negative battery cable terminal. touch the other lead to the negative battery post, completing the circuit within the multimeter, which will display the amp draw. power draw should be under 50 milliamps. this will display as 0.05 amps. if it's higher, that is your parasitic power draw.
