HITACHI Regulator: Adjustment
NOTE:
Charge relay is adjusted in same manner as voltage regulator.
- Disconnect and remove voltage regulator from vehicle. If contact points are roughened, smooth with fine sand paper. Check and adjust gaps: core gap first, then point gap.
NOTE:
Adjustment of yoke gap is unnecessary on some models.
- Adjust core gap by loosening screws attaching contact set to yoke. Move contact set upward or downward as required. Adjust point gap by loosening screw attaching upper contact. Move upper contact up or down as required to set gap to specification.
- Adjust regulated voltage by means of adjusting screw. Turn screw in to increase regulated voltage or out to decrease voltage. When correct voltage adjustment is obtained, secure with lock nut. When adjustment procedure is complete, reinstall regulator and perform on car check.
