Alternator rated at 45A for the 3.5 litre V8 twin-carburettor petrol engine.

Driven by the auxiliary belt as part of the engine charging system, it generates the electrical power that charges the battery and runs the vehicle electrical systems while the engine is running.

This is a battery-sensed unit: it regulates its output by monitoring voltage at the battery rather than at the alternator terminal, helping hold a stable charge under varying electrical load.

Frequently asked questions

What does the RTC5086E alternator do?
The RTC5086E is a Lucas 45A alternator for the 3.5 litre V8 twin-carburettor petrol engine. Driven by the auxiliary belt, it generates the electrical power that charges the battery and runs the electrical systems while the engine is running.
What does 'battery-sensed' mean for this alternator?
Battery-sensed means the RTC5086E regulates its output by monitoring voltage at the battery rather than at the alternator terminal, which helps hold a steady charge under changing load. A battery-sensed unit needs its sensing wire connected correctly, so check your wiring matches before fitting.
Which Land Rover does this alternator fit?
The RTC5086E fits the Defender (1987-2006) with the 3.5 litre V8 twin-carburettor petrol engine. It's specific to the twin-carb V8, so it won't suit fuel-injected V8s or other engines, which use alternators of different output and mounting.
What are the signs this alternator needs replacing?
A failing alternator usually shows as the battery warning light staying on, dim or flickering lights, or a battery that won't hold charge. On the twin-carb V8 a weak charge can leave the engine hard to start. Check the charging voltage at the battery to confirm before replacing.
