FAQ:
Q: Where is the voltage regulator on an alternator?
A: The voltage regulator is located inside the alternator. When the voltage regulator fails the entire alternator is usually replaced. It should be on the alternator or internal to the alternator. There will be an oblong plug for it so just look for the connecter.
Q: How do you adjust a voltage regulator?
A: If the voltage, at which the reading becomes steady, occurs outside these limits, adjust the regulator by turning the adjusting screw 1/4 turn at a time clockwise to raise the voltage or counterclockwise to lower. The adjusting screw can be found on the back of the regulator facing the firewall.
Q: What is voltage regulator and how does it work?
A: A voltage regulator is basically a beefed up emitter follower, like described above – a transistor connected to a stable reference that spits out a constant voltage, dropping the rest. They also have a built in error amplifier, which samples the output voltage (again through a divider), compares it with the reference voltage, calculates the difference, and drives the output transistor accordingly.
Q: What is a car voltage regulator?
A: An automobile voltage regulator controls the voltage produced by the car’s alternator to recharge the battery.
