Alternator - belt-driven charging unit of the A115 type, rated at 45 amps.

Driven from the crankshaft pulley, the alternator carries the vehicle's electrical load once the engine is running and returns charge to the battery. An integral regulator controls field current so that system voltage stays within limits across the whole engine speed range, while the internal rectifier converts the stator output to direct current. The 45 amp rating suits installations without air conditioning.

Symptoms of a failing unit include a charge warning lamp that stays lit, low or fluctuating system voltage, and a battery that will not hold charge. Where the fault is confined to the regulator and brushes, that assembly is separately serviceable as RTC5670.

Frequently asked questions

What does the RTC5083 alternator do?
The RTC5083 alternator charges the battery and powers the electrical system while the engine runs. It's a new Lucas-type unit. It fits Defender and Series models and replaces the original charging unit driven by the auxiliary belt off the engine.
Which Land Rovers does this alternator fit?
This alternator fits Defender 1986-2006 with the 2.25 petrol, 2.5 naturally aspirated diesel or 2.5 petrol engine, plus Series 2, 2A and Series 3. The Defender applications are for vehicles without air conditioning. Confirm your engine and spec before ordering.
What are the signs of a failing alternator?
A failing alternator usually shows as a battery warning light, dim or flickering lights, a flat battery, or a whine from the unit. On a Defender or Series the alternator keeps the battery charged. Once the internals or bearings fail the unit needs replacing.
Why does it say 'less air conditioning'?
'Less air conditioning' means this alternator suits Defenders built without factory air conditioning. Air-con vehicles can use a different bracket, pulley or higher-output alternator to drive the extra load. If your Defender has air conditioning, check the mounting and output before ordering this unit.
