What Causes Unstable Battery Voltage?
1 Answers
Unstable voltage may be caused by a damaged alternator voltage regulator. Below are the warning signs and causes of automotive battery failure: 1. Precursor symptoms of battery failure: The vehicle can start, but the dashboard or system will emit warning sounds during startup. 2. Symptoms of insufficient voltage: One scenario is that low-current devices like remote door unlocking, dashboard, and radio can function normally, but the starter motor fails to work, producing only motor sounds. Another scenario is that the motor runs normally but fails to start the engine. This occurs because the battery voltage is too low for modules to operate properly, preventing system unlocking. 3. Symptoms of complete power loss: The remote cannot unlock doors, with no response whatsoever.
