How to replace the Alternator Brush and Voltage Regulator in a Pontiac Firebird?

Remove the alternator and mark the front and rear frames for reassembly. Take out the four bolts connecting the frames and separate them. Detach the stator from the rectifier bridge and remove the diode trio. Remove the brush holder and the voltage regulator. For installation, reverse the steps. When reinstalling the brush holder, press the brushes in, use a straightened paper clip to hold them, and only remove the clip once the frames are bolted together.

Pontiac Firebird Voltage Regulator

The Voltage Regulator in Pontiac Firebird vehicles maintain the output of the alternator in a particular voltage level to ensure that the battery and the electrical system is not destroyed. The regulator controls the field current in the alternator rotor by comparing the battery voltage to the current systems demand, to maintain a charging voltage between 13.5V and 14.5V. Older Firebird models used to have mechanical voltage regulators that were replaced by the newer and better electronic solid-state regulators. These modern regulators are capable of going 'ON' and 'OFF' much faster as compared to the mechanical ones with enhanced resultant control on the charging system. Recent internal regulators which are installed with the alternator and managed through the Powertrain Control Module are widely used in the Pontiac Firebird boosting the efficiency and functionality of the cars.

Each OEM Pontiac Firebird Voltage Regulator we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part.
