Will it fit my Focus ST?
Match the amp rating and pulley type (clutch vs solid). Stop/start cars often need a specific unit.
Tip: filter by your reg on eBay's compatibility check, or match the part number stamped on your old unit.
Signs your Focus ST alternator needs replacing
- Battery/charge warning light
- Dim or flickering lights
- Flat battery / no start
- Whining or squealing belt-end
Fitting it yourself
Belt off, two mounts, wiring — 1–2 hrs. Watch for seized lower bolts.
