Alternator - belt-driven charging unit of the A133 type, rated at 65 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 higher 65 amp rating covers installations carrying the additional current draw of 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 is the RTC5218E A133 alternator?
The RTC5218E is an A133 65 amp alternator for the Defender. It's driven by the engine and charges the battery while powering the electrics. It fits the 2.25 petrol, 2.5 petrol and diesel with air conditioning, and 3.5 V8 twin carb.
Where is the alternator mounted on the engine?
The RTC5218E alternator mounts on the left side of the Defender engine, driven by the auxiliary belt. Position and bracketry match the A133 65 amp unit used on the 2.25/2.5 four-cylinder and 3.5 V8 twin carb applications.
What are the signs the alternator needs replacing?
A failing alternator typically shows as a battery warning light, dim lights or a flat battery on the Defender. If the A133 stops charging at its 65 amp output, the RTC5218E replaces it to restore reliable charging.
