Mitsubishi Eclipse charging system malfunction with new alternator causing battery drain and car shutdown on Mitsubishi Eclipse

Some Mitsubishi Eclipse owners report experiencing charging system malfunctions even after replacing the alternator, resulting in battery drain and car shutdown. These issues may be indicated by the battery light, which signals a problem with the charging system, often linked to the alternator. Owners have noted that if the battery is not charging despite new components, it could suggest a persistent issue with the charging system. Additionally, a drained battery when the car is not running may indicate parasitic power loss or a faulty battery, while depletion during driving could point to alternator problems. Reports of charging issues in the 2018+ Mitsubishi Eclipse Cross suggest that service or revisions to the EV system may be necessary. Troubleshooting should include checking for battery draws, inspecting fuses, cleaning grounds, and looking for visible damage to charging components. If problems persist after multiple replacements, further investigation into corroded wires or faulty connections may be required. Testing alternator output voltage and monitoring current levels are essential steps for diagnosing these charging system malfunctions.
