Key Technical Specifications

• Output Voltage: 14 V DC – the standard for contemporary vehicle charging systems.
• Maximum Current: 90 A – sufficient to support high‑draw accessories such as advanced infotainment units, LED lighting arrays, and power‑hungry diagnostic tools.
• Operating Frequency: 60 Hz (standard for automotive alternators).
• Voltage Regulation: Integrated electronic regulator ensures stable output across varying engine speeds.
• Mounting Type: Standard bracket mounting compatible with most front‑engine configurations.

Design and Build Quality

The alternator features a stainless steel rotor and a high‑grade copper winding, which together provide excellent thermal conductivity and resistance to corrosion. The housing is constructed from durable aluminum alloy, offering lightweight strength while maintaining heat dissipation efficiency.

Rotor and Stator Construction

The rotor’s magnetic core is engineered for optimal flux density, ensuring efficient conversion of mechanical energy into electrical power. The stator windings are insulated with a high‑temperature varnish that withstands the rigors of automotive operation, extending the unit’s lifespan even under extreme conditions.

Electrical Performance

The DENSO DAN996 Alternator incorporates an advanced voltage regulator circuit that automatically adjusts output based on battery state and engine load. This intelligent regulation prevents overcharging, protects the battery, and reduces electrical noise.

Current Delivery Curve

During low RPM operation, the alternator delivers a steady 90 A, while at higher RPMs it can supply up to 120 A if required by accessory demands. This flexibility makes it ideal for vehicles equipped with power‑intensive systems.

Compatibility and Applications

The alternator is specifically engineered for:

• Alfa Romeo MiTo
• Fiat Grande Punto (3/5‑door)
• Punto Evo (3/5‑door)
• Other vehicles within the Fiat and Alfa Romeo family that require a 14 V, 90 A alternator.

Its modular design allows for straightforward installation in both OEM and aftermarket setups. The unit’s dimensions and mounting points match those of the original equipment, ensuring a seamless fit without the need for extensive modifications.

Installation Guidelines

1. Disconnect the battery: Ensure safety by removing the negative terminal before any work.
2. Remove the old alternator: Detach the drive belt, disconnect electrical connectors, and unbolt the unit from its bracket.
3. Mount the DENSO DAN996 Alternator: Secure it to the engine block using the supplied mounting bolts and brackets.
4. Reconnect the battery: Attach the negative terminal after all electrical connections are verified.
5. Test the charging system: Start the engine and verify that the alternator is producing a stable 14 V output at idle and higher RPMs.

Maintenance Tips

• Inspect the drive belt for wear and replace if necessary to maintain proper tension.
• Check electrical connections periodically for corrosion or looseness.
• Ensure that the alternator’s cooling vents remain unobstructed to prevent overheating.
