| Outputs & variants | Every alternator listed is 150 A with a freewheel pulley and COM/LIN plug, so the engines are distinguished by pulley rather than output. The 7-rib 49-50 mm units (Bosch 0 986 084 690, Hella 630-661, Lucas LRA03925, AS-PL A3565S) are the Bosch-pattern alternator for the 1.5 dCi diesel, while the 6-rib 55 mm units (Valeo 444243, Hella 637-461, AS-PL A0594S) suit the 1.2 DIG-T petrol. |
| Genuine (OE) numbers quoted | FG15T071 (AS-PL A3565S); F000BL50R4 (AS-PL A0875S); F000BL0825 (AS-PL A0594S); F000BL0841 (AS-PL A0590S); F000BL08E0 (AS-PL A0594(SEG)); F000BL08F5 (AS-PL A01235(SEG)). |
| Fitment notes | Count the ribs on the old pulley before ordering, as both 6-rib and 7-rib 150 A units are sold for this car; Bosch recommends renewing the auxiliary belt with the alternator, and the Bosch, Valeo and Lucas exchange units carry a core charge refunded on return of the old part. |
A Genuine, Specific Root Cause Worth Checking First — Nissan Pulsar Alternator
A documented, specific fault worth checking before assuming the alternator itself has failed: the factory wiring loom connecting to the alternator's voltage regulator plug is relatively short, and over time the wires can rub through and start to fray at this specific connection point, causing exactly the intermittent charging faults and warning lights that get blamed on the alternator itself.
It's also worth knowing that a genuine alternator fault doesn't always trigger the dashboard warning light — one documented case saw persistent, confirmed alternator symptoms over an extended period with the warning light never illuminating even once.
Nissan Pulsar Alternator: Often Blamed on the Battery Instead
Early on, a weak Nissan Pulsar 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.

Nissan Pulsar Alternator: What It Does
On the Nissan Pulsar, 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.
