The voltage regulator ensures that the maximum voltage in the circuit remains consistent. As a result, the alternator can be stimulated to enhance or decrease energy output. The goal is to provide a steady stream of current that can power the ship. By charging the battery, the extra power is put to good use. If your regulator fails, you may notice flickering gauges on your instrument cluster, a malfunctioning electrical component, or two.
