A dead battery causing your car to not start is never fun. You recharge the battery or replace it and the vehicle’s alternator is functioning properly, but the car doesn’t start again the next day. The battery is dead again! This is called a parasitic draw or an unintended battery drain. Ever accidentally leave a dome light on and kill the battery? That’s just one example. Check out the video below to learn how to perform parasitic draw testing.
