Chevrolet Caprice Voltage Regulator
The Voltage Regulator in Chevrolet Caprice vehicles play an important role of monitoring and preventing high Voltage output of the alternator from spoiling the battery and other parts of the electrical system. It regulates the battery voltage at 13.5 to 14.5 volts by monitoring the battery voltage and the load present in the system and varying the current to the field of the rotor of the alternator. When the battery needs to be charged the regulator draws more current through the field but when battery is fully charged the regulator reduces the amount of current to that battery in order not to overcharge the battery. The Chevrolet Caprice car has used various varieties of Voltage Regulators in the course of the years. First, mechanical, externally adjustable voltage stabilizers using coils and contact points were characteristic, the instability of which and wear of the contact points led to overcharging. These were succeeded by digital or solid state which are more efficient than the magnetic and switch at the rate of 7000 cycles per second. In today's Caprice car models, there are internal regulators that are installed with the alternator, while the Voltage Regulator function is usually under the control of the Powertrain Control Module or PCM through which many factors are considered in controlling the charging system output.

Chevrolet Caprice Voltage Regulator Parts Questions & Experts Answers
- Q: How to troubleshoot and adjust a voltage regulator on Chevrolet Caprice?A: A discharged battery is often caused by a fault in the voltage regulator, so before testing the unit, check the drivebelt tension, test the battery's condition, and inspect the charging circuit for loose connections and broken wires. Ensure that lights or other electrical accessories are not inadvertently left switched on. Verify the generator indicator lamp for normal illumination with the ignition on and off, and with the engine idling. Disconnect the battery ground cable and the harness connector, then remove the screws securing the unit to the vehicle. Avoid cleaning the voltage regulator or field relay contacts with abrasive materials, as this can damage the contact material. Use a feeler gauge to check voltage regulator point and air-gap adjustments, ensuring the upper contacts open while the lower contacts just touch, making adjustments by carefully bending the upper contact arm and turning the nylon nut for air gap adjustments. The field relay point opening can be adjusted by bending the armature stop, with the air gap checked when the points are just touching and adjusted by bending the flat contact support spring. The field relay typically operates satisfactorily even if the air gap is outside specified limits and should not be adjusted if the system is functioning well. Installation follows the reverse of the removal procedure, ensuring the rubber gasket is in place on the regulator base.
