Chrysler LeBaron intermittent parasitic battery drain issue causing slow crank and check engine light on Chrysler LeBaron

Some Chrysler LeBaron owners report experiencing intermittent parasitic battery drain issues that lead to slow engine cranking and trigger the check engine light. Symptoms of this problem include dead batteries after the vehicle has been parked, dimmed lights, and difficulty starting the engine. Common causes identified by owners include improperly installed aftermarket accessories, faulty relay switches, malfunctioning alternators, damaged wiring, and short circuits. This parasitic drain can result in a dead battery without warning, potentially leaving drivers stranded due to a no-start condition. To prevent these issues, it is advised to ensure proper installation of accessories, check relay switches, maintain the alternator, inspect wiring, and avoid short circuits. Owners can also test for parasitic draw using methods like the ammeter test or perform a DIY load test to assess battery health. Understanding these factors can help effectively diagnose and resolve the battery drain issue in the Chrysler LeBaron.
