Frequently asked questions

What does the RTC5682 alternator do?
The RTC5682 is a Lucas A127-type alternator rated at 45A. It's driven by the auxiliary belt from the crankshaft and converts engine rotation into regulated DC current, charging the battery and powering the vehicle's electrical system. It fits Defender and Range Rover Classic models with 2.5 petrol, 2.5 naturally aspirated diesel, or 200 TDi engines.
Which Land Rover models and engines does this alternator fit?
This 45A A127 alternator fits the Land Rover Defender from 1983 to 2006 with 2.5 petrol, 2.5 NA diesel, or 200 TDi engines, and the Range Rover Classic from 1992 to 1994. On Range Rover Classic it applies from VIN MA647645, so check your chassis number to confirm.
What are the signs a Land Rover alternator needs replacing?
Typically a failing alternator shows as a battery warning light on the dash, dim or flickering headlights, or a battery that keeps going flat. On these older Defender and Range Rover Classic models, worn brushes or a failed regulator inside the A127 unit are usually the cause.
How do I know if I need the 45A version rather than a higher-output alternator?
The RTC5682 is the 45A A127 alternator. The A127 was fitted in several output ratings across Land Rover engines, so confirm your original unit is the 45A version before ordering. Vehicles running higher electrical loads may have been fitted with a higher-amp alternator.
