Abnormal Battery Discharging

WARNING: This page is about a different car, the 2008 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.

Any of the following conditions can result in abnormal battery discharging:

  1. A inoperative or incorrect charging system component. Refer to CHARGING SYSTEM for additional charging system diagnosis and testing procedures.
  2. A inoperative or incorrect battery. Use the appropriate battery tester and refer to the specific Battery diagnosis and testing procedures.
  3. A inoperative circuit or component causing excessive ignition-off draw.
  4. Electrical loads that exceed the output of the charging system. This can be due to equipment installed after manufacture, or repeated short trip use.
  5. A inoperative or incorrect starting system component. Refer to STARTING SYSTEM for the proper starting system diagnosis and testing procedures.
  6. Corroded or loose battery posts and/or terminal clamps.
  7. Slow driving speeds (heavy traffic conditions) or prolonged idling, with high-amperage draw systems in use.
