This is a 12V 80A alternator, the core component responsible for generating electrical power to charge the battery and run the vehicle's electrical systems while the engine is running. It converts mechanical energy from the engine into electrical energy, ensuring all accessories function correctly and the battery remains charged. A failing alternator will result in a dead battery, dimming lights, and the eventual shutdown of the vehicle due to lack of power.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of an alternator problem is often a battery warning light illuminating on the dashboard. If ignored, the battery will gradually lose its charge, leading to dimming lights, slow engine cranking, and eventually, the engine shutting down due to insufficient electrical power. A complete alternator failure will render the vehicle inoperable.

Installation Tip

Always disconnect the battery before removing or installing the alternator to prevent electrical shorts. Ensure the drive belt is properly tensioned after installation; too loose and it will slip, too tight and it can damage the alternator bearings.

Service Note

When replacing the alternator, inspect the condition of the drive belt and pulley for any signs of wear or damage.
