Volvo S60 Alternator: Often Blamed on the Battery Instead
On the Volvo S60, a failing alternator and a simply weak battery share almost the same symptom set at first: dim lights, sluggish starts, charge that won't hold. Mixing the two up is common, which is why plenty of people replace the battery only to find themselves back at the garage shortly after.
Volvo S60 Alternator: What It Does
The Volvo S60's electrical systems and battery charging both depend on the alternator generating electricity whenever the engine runs. If it's healthy, the battery's job shrinks down to starting the engine and handling brief surges in demand, not powering everything else on its own.

A Genuinely Useful, Real Diagnostic Technique Worth Trying — Volvo S60 Alternator
If you're chasing an alternator noise, this is genuinely worth trying before assuming the whole unit has failed: some Volvo alternators use a one-way clutch or decoupler pulley rather than a solid pulley, and this specific component can fail and cause noise on its own. With the belt removed, grab the alternator pulley and sharply move it in both directions — you should feel genuine resistance in one direction and free slipping in the other.
It's also genuinely worth knowing that when replacing an alternator yourself, it's worth double-checking the exact part number against your VIN, since not every alternator that physically bolts on is necessarily the correct electronic specification, worth confirming before fitting a replacement that could otherwise trigger warning lights despite good connections.
