Voltage Regulator
A component that maintains stable electrical output from the alternator.
The voltage regulator prevents overcharging or undercharging by controlling alternator output. It monitors system voltage and adjusts current flow dynamically. Integrated regulators are built into modern alternators for compact design. A failing regulator causes dimming lights, fluctuating voltage, and battery issues. Consistent regulation ensures electrical system stability and protects sensitive ECUs from voltage spikes.
