Winter challenges: Starter motors & alternators

By autotech-nic on January 12, 2024

Vehicles face increased demands on their electrical systems throughout the colder months, leading to a higher rate of alternator failures. Autoelectro’s Harnek Bhogal highlights how its remanufactured units rise up to the challenges…

The main cause of the heightened rate of alternator failures in winter lies in the increased load placed on these crucial components. Drivers heavily rely on electrical systems during colder months, such as heaters, defrosters, headlights, and various climate control features. This increased electrical load puts additional strain on the alternator, as it must simultaneously power these systems while maintaining the battery’s charge.

Harnek says: “Our units are manufactured with precision engineering, high-quality materials and adhere to the most stringent manufacturing standards. The components used in our alternators are durable and reliable, reducing the likelihood of failure, even in extreme cold temperatures.

“In contrast, ‘copy’ units often compromise on materials and quality control, making them more susceptible to malfunction in harsh environmental conditions. For motor factors, workshops and end-users, why take the risk?”

“Our alternators are designed for optimal proficiency, producing electrical power with minimal waste in the form of heat. This efficiency becomes particularly crucial in colder weather, where the engine may need to work harder to generate power. A higher quality alternator helps minimise strain on the engine, enhancing fuel efficiency, and reducing wear and tear on the vehicle’s electrical system.”

But what about starter motors?

The ‘normal’ reasons for its failures, including overheating, excessive cranking, and mechanical issues, such as being stuck in the mesh. While the faults observed in returned cores remain consistent, the winter conditions exacerbate these issues. The strain on rotating electrics during winter mornings is unparalleled, making it crucial for vehicles to be equipped with reliable starter motors.

Autoelectro’s OE-spec starter motors and alternators are backed by a two-year warranty and the firm provides customers with technical support.
