Alternator Control Unit (CRX)

Alternator control unit senses changes in engine load and controls alternator to compensate for these changes. The control unit varies rate of charge depending on driving conditions. The control unit also activates the idle boost solenoid to increase idle speed during increased engine load.

Testing of the control unit is not available from the manufacturer. For control unit wiring see WIRING DIAGRAMS - CRX article.
