OEM Part Number: A003TG3391 (genuine alternator — confirm via VIN) — aftermarket alternators Hella 8EL 011 711-771 / AS-PL A5437S
| Alternators (aftermarket) | Hella 8EL 011 711-771 (65 A, rigid single-groove pulley, 86 mm, new, includes vacuum pump, older engines only); AS-PL A5437S (95 A, freewheel pulley, 6 ribs, 65 mm, new, PL_4100 plug); AS-PL A5614S (90 A, freewheel pulley, 6 ribs, 65 mm, new, PL_4100 plug); AS-PL A5628S (130 A, freewheel pulley, 6 ribs, 64 mm, new, PL_4100 plug); AS-PL A5589S (180 A, freewheel pulley, 6 ribs, 64 mm, new, PL_2305 plug); BV PSH 505.523.130.130 (130 A, freewheel pulley, 6 ribs, 65 mm, new); Rotovis 9091736 (180 A, freewheel pulley, 6 ribs, 65 mm, remanufactured, COM plug). |
|---|---|
| Outputs & variants | The Series 5 L200 is listed with 90-95 A, 130 A and 180 A 6-rib freewheel-pulley alternators on 64-65 mm pulleys. The 95 A unit is the base 2.4 DI-D specification, the 130 A unit the higher-specification 2.4 DI-D, and the 180 A unit with the PL_2305 / COM plug is for vehicles with stop-start and the heavier electrical load. The 55-90 A single and twin-groove rigid-pulley units with integral vacuum pump shown alongside belong to the older 2.5 TD L200 and do not fit the KJ. |
| Genuine (OE) numbers quoted | A5TL0781ZT (AS-PL A5437S); A5TG3681ZT (AS-PL A5614S); A002TX4981ZT (AS-PL A5628S); A2TV1481ZT (AS-PL A5589S); A5TL0291ZT (AS-PL A5328); A3TN0299 (AS-PL A5072); A2T01483 (AS-PL A5006). |
| Fitment notes | Check the rating stamped on the old unit before ordering, because the three outputs use different plugs and are not interchangeable; the AS-PL numbers above all end ZT and reproduce the Mitsubishi part numbers exactly. The 180 A Autoelectro and Rotovis exchange units carry a core charge of up to £125.59 refunded on return. |
Mitsubishi L200 Alternator: Often Blamed on the Battery Instead
Early on, a weak Mitsubishi L200 battery and a dying alternator look almost identical — dim lights, sluggish starts, a car that won't hold its charge — which is exactly why so many people fit a new battery and end up back at the garage weeks later, the actual fault still unaddressed.
Mitsubishi L200 Alternator: What It Does
On the Mitsubishi L200, while the engine runs, the alternator generates the electricity that charges the battery and powers the car's electrical systems directly. With a healthy alternator, the battery's real job becomes starting the engine and covering brief demand spikes, rather than running the electronics on its own.

A Genuinely Specific, Real Technical Finding Worth Knowing About Overcharging — Mitsubishi L200 Alternator
Most alternator faults get discussed in terms of undercharging, but this is genuinely worth knowing about the opposite problem: a faulty voltage regulator within the alternator can actually overcharge the battery rather than undercharging it, and this has been documented literally causing the battery to boil and fail as a result. This can go on to damage engine electronics and has been linked to immediate stalling shortly after startup — worth knowing this specific failure pattern if you're facing stalling alongside signs of a battery that's failed unusually quickly or shows physical signs of damage like bulging or leaking.
It's also genuinely worth knowing that replacing the alternator itself doesn't require any CAN-bus reset or special programming afterward — worth knowing this if you're considering doing the job yourself and were concerned about needing specialist diagnostic equipment.
