Key Technical Specifications

• Output: 120 A at 14 V – sufficient to charge batteries and run accessories in medium‑sized cars, vans, and light trucks.
• Voltage Regulation: 12.6–13.8 V (typical automotive range) with a built‑in regulator for stable output under varying load conditions.
• Mounting Type: Standard B+ (M8) bolt pattern, ensuring compatibility with most OEM and aftermarket engine bays.
• Dimensions: Ø 49 mm housing diameter; compact design fits within tight engine compartments without modification.
• Freewheel Pulley: Integrated pulley allows the alternator to spin freely when the engine is off, reducing parasitic load on the battery.
• Operating Temperature: -40 °C to +120 °C – suitable for extreme climates and high‑heat environments.

Vehicle Compatibility Matrix

The alternator’s versatile design makes it a fit for numerous models across several manufacturers. Below is an overview of the most common applications:

Design Highlights

• Durable Housing: Made from high‑strength aluminum alloy to resist corrosion and mechanical shock.
• High‑Efficiency Rotor: Optimized magnetic flux for maximum power output while minimizing heat generation.
• Integrated Cooling Fan: Maintains optimal operating temperature even under heavy electrical load.
• Low Noise Operation: Precision bearings and balanced rotor reduce vibration, ensuring a quiet ride.

Installation & Maintenance Tips

1. Mounting: Align the B+ (M8) bolt pattern with the engine block. Tighten in a star sequence to avoid warping.
2. Belt Tension: Use a torque wrench to set belt tension according to manufacturer specifications; an over‑tightened belt can damage the alternator’s pulley.
3. Electrical Connections: Connect the regulator cable, battery cable, and ground wire securely. Verify polarity before powering up.
4. Periodic Inspection: Check for loose bolts, belt wear, and signs of overheating (discoloration or oil residue).
