Bad Voltage Regulator – Symptoms, Causes, & Testing
The voltage regulator monitors your battery''s real-time current and voltage to determine how much voltage to send to it. It sends more power when the battery is low, and when it gets fully charged, it diverts the voltage to the ground, preventing the battery from overcharging and eventually blowing up.
