Peugeot Partner Alternator: Specs, Fitment & Common Faults
On the Partner, a whining noise that gets louder under load is often the alternator's clutch pulley seizing, not the alternator itself failing — worth confirming before a costly replacement.

| Outputs & variants | The Partner Tepee is listed with 70-90 A, 120 A, 150 A and 180 A alternators. The 70-90 A units suit the 1.6 petrol, the 120 A freewheel units the 1.2 PureTech and early 1.6 HDi without stop-start, and the 150 A 54 mm freewheel units are the main 1.6 HDi and 1.6 BlueHDi fitment, offered with either the older L-DFM plug (Lucas LRA02226, Bosch 0 986 046 240) or the later COM/LIN plug (Lucas LRA03457, Bosch 0 986 082 240). The 180 A Valeo 440999 is for e-HDi vans and MPVs with stop-start. |

| Fitment notes | Two different plugs are used on the 150 A alternators, so match the plug on the old unit as well as the output, and do not fit a standard unit to a stop-start vehicle; the Bosch 0 986 046 240 exchange unit carries a £100.47 core charge and the Valeo 440999 £152.37, refunded on return of the old alternator. |
A Genuine, Well-Documented Cause Worth Checking First: The Clutch Pulley — Peugeot Partner Alternator
A well-documented, genuinely useful thing to check before assuming the alternator itself has failed: a groaning or whining noise from the belt area, particularly noticeable as engine revs rise, is very often the alternator's clutch pulley seizing up rather than the alternator's internal charging components failing. One documented case describes exactly this pattern — a loud whine assumed to be a cambelt or water pump issue, which disappeared entirely once the drive belt was removed, confirming the noise was coming from something belt-driven rather than the engine internals. Removing the belt and turning the pulley by hand in both directions is a genuinely useful test: it should lock solid in the normal drive direction and spin freely the other way — if it doesn't behave this way, the clutch pulley has failed rather than anything inside the alternator.
Peugeot Partner Alternator: Often Blamed on the Battery Instead
On the Peugeot Partner, a weak battery and a failing alternator produce almost identical symptoms at first — dim lights, slow starts, a car that won't hold charge — which is exactly why so many people replace the battery, only to be back at the garage a few weeks later with the real culprit untouched.

Peugeot Partner Alternator: What It Does
The Peugeot Partner's alternator generates electricity while the engine runs, charging the battery and powering the car's electrical systems directly. A healthy alternator means the battery is mostly there for starting the engine and covering brief demand spikes — not for actually running the car's electronics on its own.
