Parasitic draw

A parasitic battery drain is when an abnormal current draw occurs after having turned off the engine.

Usually, this is caused by a short circuit or a module that refuses to go to sleep mode. 

To test for a parasitic draw, you will need a multimeter that can measure current.

  1. Turn off the car.
  2. Locate and make accessible all fuse panels. Meaning keeps doors open, hood open, turn or any other place so that you can access the fuse box. 
  3. Let the car sit for at least 15 minutes. 
  4. Start pulling fuses one at a time a measure current draw at each fuse. 
  5. When you find a circuit that has an excessive draw, you have found the problem.
