Modern starting & charging for your classic

Upgraded alternators, dynators and starter motors


Charging systems for classic cars


A reliable charging system is essential for any classic car, particularly when modern electrical loads are involved. Original dynamos and early alternators were designed for a time when electrical demand was minimal and vehicles were used daily. Modern usage patterns place far greater strain on these systems.


Ageing charging components often struggle to maintain battery health, especially at idle or during short journeys. Symptoms typically include flat batteries, dim lighting, and inconsistent electrical behaviour.


Modern charging upgrades


Where originality must be preserved, a dynator offers an effective solution. Dynators house modern alternator internals within a traditional dynamo casing, providing improved output, reliable charging at idle, and long-term durability while retaining a period-correct appearance.


For vehicles already fitted with alternators, modern high-output replacements provide a significant improvement. Units delivering between 65 and 200 amps offer greater electrical stability, improved battery charging, and sufficient capacity to support additional accessories such as electric cooling fans, upgraded lighting, and charging ports.


Correctly specified and installed, modern charging upgrades improve reliability without compromising the character of the car.

Starting systems for classic cars


Starting performance is one of the most immediate indicators of a classic car’s overall electrical health. Starter motors draw very high current, and any weakness in the system is quickly exposed.


Traditional direct-drive starter motors often suffer from wear, heat soak, internal corrosion, and voltage drop caused by ageing wiring and earth connections. The result is slow or inconsistent cranking, particularly when hot or after periods of inactivity.


High-torque starter motors


Modern high-torque starter motors provide a clear improvement in starting reliability. By using a more efficient motor and gear-reduction design, they deliver greater cranking torque while drawing significantly less current.


Key benefits include faster starting, reduced strain on batteries and wiring looms, improved hot-start performance, and greater reliability on higher-compression engines.


Well-engineered starter motors designed specifically for classic applications ensure correct engagement, long service life, and rebuildability, supporting both reliability and sustainability.
