The voltage regulator is a solid-state, non-adjustable unit integral with the alternator. The alternator must be disassembled to remove the regulator.
Testing or replacing individual components in the alternator is not practical or economical for a do-it-yourself mechanic. The tools needed are expensive and would not be practical to purchase to use only a few times. Complete rebuilt alternators can be purchased through your local parts distributor for a fraction of the cost of a new unit.
REMOVAL & INSTALLATION

- Remove the alternator assembly, as outlined in the Alternator removal and installation procedures in this section.
- Mark the end frames to ease reassembly.
- Remove the four thru-bolts and separate the drive end frame assembly from the rectifier end frame.
- Remove the three attaching nuts and regulator screws.
- Insert a small piece of wire in the brush holder as shown in the Regulator illustration. Position the regulator in the rectifier end frame and tighten the attaching screw and nuts.
- Install the rectifier end frame in the same position as removed and tighten the four thru-bolts. Make sure to remove the brush retaining wire.
