An alternator is an essential component of a vehicle’s charging system. It converts mechanical energy from the engine’s crankshaft into electrical energy (AC), which is then converted to DC power to charge the battery and supply electricity to all electrical components — including lights, ECU, ignition, and infotainment systems — while the engine is running.
A failing alternator can show several warning signs, including:
Dim or flickering headlights
Battery warning light on the dashboard
Slow cranking or dead battery
Unusual whining or grinding noise from the alternator pulley
Electrical malfunctions, such as power window or A/C fluctuations
It’s recommended to test alternator voltage output regularly (should read around 13.8V – 14.4V at idle).
You can confirm compatibility by checking the OEM part number, engine code, or vehicle VIN. Also, ensure the following specifications match:
Voltage (12V / 24V)
Amperage (e.g., 90A, 120A, 150A)
Pulley type (single or multi-groove)
Mounting points and plug type
If unsure, contact us with your vehicle make, model, year, and engine details for assistance.
Yes. A defective alternator can cause undercharging, leading to a weak battery, or overcharging, which can overheat and damage the battery. Irregular voltage spikes may also harm sensitive electronic components like the ECU (Engine Control Unit) or sensors. Regular voltage checks ensure optimal system health.
A quality alternator generally lasts between 80,000 – 150,000 km, depending on driving conditions and electrical load. Factors that reduce lifespan include:
Frequent stop-start driving
High electrical load (A/C, lights, sound systems)
Worn belts or pulleys
Exposure to engine oil or coolant leaks
Timely belt replacement and system checks can extend longevity.
Yes. All our alternators undergo bench testing for output voltage, current load capacity, and bearing performance before dispatch. We supply brand-new or remanufactured units meeting OEM standards, backed by a warranty (duration may vary by brand and model).
