Alternators & Starter Motors


While the battery is essential for starting your car when it’s off, the alternator keeps your car alive when the engine is running. The alternator powers most car’s electronic components while you’re driving around or idling, including your headlights, electric steering, power windows, windshield wipers, heated seats, dashboard instruments, and radio. The alternator supplies all of them with direct current (DC) power. Your alternator is also responsible for charging your car battery while driving.

Our complete range of alternators offers high-quality and tested components. They cover a wide range of vehicles, covering up to 90% of the vehicle car parc in UK and Ireland.  All products are engineered to OE specifications.

Starter Motors

A starter motor is simply an electric motor that turns your engine on when you switch the ignition. To do this, the starter motor requires a lot of torque to turn the engine at such fast speeds, so that it pulls fuel and air into the cylinders and compresses them at the same time.

While sounding like a simple task, great forces and strain are but upon these parts, ensuring the right quality of materials and thorough testing are key.  At Starline we put our products through rigorous testing, so your safe in the knowledge that when you come to fit our products to a customers vehicle you can fit with confidence.
