WAI D201XHD Extra Heavy Duty Alternator Voltage Regulator, 12V, 14.8V Set Point

The WAI D201XHD voltage regulator (also called an alternator voltage regulator) is an extra heavy duty replacement for Delco AD230 series alternators. It controls alternator output so the charging system stays within its target voltage range. That protects the battery and electrical components.

Key Features:

• 12 volt, B-circuit regulator with P-L-I-S terminals
• 14.8V set point
• ASVR (Alternator Sensing Voltage Regulator) design
• Welded construction with no solder joints, for high-temperature reliability and longer field life
• Current limiting
• Thermal shutdown protection
• Protection against shorted field, shorted lamp circuit and load dump
• Designed for DR4402 and DR4403 series rectifiers with a screw-down collar

Cross-References:

• Replaces Delco 10494747 (stamped 4747, or regulator and rectifier assembly stamped 4743)
• Delco unit no. 10480229
• Lester no. 8238

This regulator is built to match OE functions and performance. It is a dependable replacement for restoring proper charging system voltage control.
