Parts
Used alternators and startersDiagnostics available
A starting or charging symptom does not always identify the failed part. Diagnostics are available in the workshop before an alternator or starter is bought.

What people describe
“It cranks slowly, like the battery is flat, but the battery is new.” Usually a voltage drop — a corroded earth strap or a tired main lead — rather than the starter itself.
“The battery light comes on and the headlights dim at idle.” That points at the alternator or its belt and pulley, and a charging-voltage check helps separate them.
“It clicks once and nothing happens.” Could be the starter solenoid, could be the ignition switch, could be a relay. Three different parts, one identical symptom.
Diagnosis before parts
We measure what is actually happening while the key is turned: cranking voltage, charging voltage, voltage drop across the earths. Nothing gets replaced on a guess, because on a starting fault a guess costs a whole part and fixes nothing.
It is worth saying that a bad earth causes more strange electrical faults on these vans than failed components do, and it costs nothing to put right once it is found.
The part itself
Alternators differ by output and by pulley type on the same model, and starters differ by tooth count and by the gearbox they bolt to — so the registration is what confirms the fit, along with the engine it identifies.
You can collect the part in Kettering or leave the van and we will fit it. Stock changes as Sprinter, Master, Movano and NV400 vans come in. If a part we sell turns out to be faulty, we replace it.
