Description
For upgraded charging systems, this Denso style alternator uses 90 A charging output, aluminum case construction, and a V-belt, 1-groove, 2.610 in. outside diameter pulley layout to help support added electrical accessories.
Charging Output & System Support
The 90 A amperage rating helps support electric fans, lighting, ignition components, fuel pumps, audio equipment, and additional electrical accessories. The 12 VDC rating keeps it aligned with common automotive charging-system requirements. The Denso case family provides the charging-system layout used for compatible brackets, wiring, and mounting geometry. This makes it useful for street-driven builds, restorations, and upgraded accessory systems.
Pulley & Belt Alignment
The V-belt, 1-groove, 2.610 in. outside diameter pulley setup is intended to match the selected accessory drive arrangement. Verify belt type, pulley offset, and bracket position before installation.
Case Construction & Cooling
The aluminum case uses a powder-coated finish with a 13.200 in. case circumference to balance durability, serviceability, and underhood presentation. The internal fan design helps support heat management during accessory load and engine-bay operation. External fan included: No.
Installation & System Matching
Confirm the mounting configuration with 6.150 in. between mounting feet. Regulator type: Internal. External regulator included: No. One-wire capable: Yes. Terminal quantity: 1. Ground type: Case ground. Rotation direction: Clockwise. Verify charge-wire size, connector style, pulley alignment, bracket spacing, and engine-bay clearance before installation.
