Problem overview

Some Dodge Challenger owners report experiencing a persistent battery light while driving, despite having installed a new battery and alternator. This issue may stem from faulty battery connections that keep the warning light illuminated, or a malfunctioning battery sensor that inaccurately signals a problem. Additionally, some owners encounter electrical issues within the vehicle's wiring that trigger the battery light, even with new components in place. In certain cases, the problem may relate to the engine controller's voltage regulation, which means replacing the alternator alone might not resolve the issue. It is recommended that owners conduct tests on the battery and alternator viability, as well as use a multipurpose battery tester to assess the health of these components. Promptly addressing these underlying issues is crucial to ensure the proper functioning of the charging system in the Dodge Challenger.
