Description:
The voltage regulator is designed to stabilize and maintain maximum voltage output at a constant rate. This is done by adjusting how much energy the alternator outputs in order to protect sensitive components in the electrical system. Excess power output is redirected towards charging the battery. Some signs of a bad regulator include flickering interior lights and sporadic increases or decreases in power; however, in some cases the signs are slight enough to not be noticeable.
Note:
Voltage Regulators and Alternators are paired components within the electrical system and should be replaced in pairs. It is common for these parts to cause their counterpart to go bad, especially after replacing only one of the two. Specifically, a bad voltage regulator can cause a good or even brand new alternator to go bad, and the reverse is also true. We recommend having both your alternator and battery tested prior to ordering, in addition to testing your current voltage regulator, in order to confirm the source of the issue you are seeing.
1977 Note:
1977 models had a split in the middle of the production year (February/March) where the alternators switched from external to internal regulators. As with many parts, this timeframe was not a hard switch, and it isn't uncommon for a late production car to still have an external regulator. If your car was produced during the 1977 model year, please inspect your car and determine whether you have an external regulator or not. Please give us a call at (714)639-2620 for assistance.
