What decides the cost of repairing, reconditioning or replacing an alternator, and when each option makes sense. We do not publish flat prices, because they depend on the unit. Send us the part number and we will tell you.
Repairing an alternator means fixing the fault that stopped it charging. Reconditioning goes further: the unit is stripped, inspected and rebuilt with the parts that wear replaced, then tested under load. Replacing means fitting a different unit, either new or reconditioned. A proper reconditioning job replaces exactly the parts that fail, which is typically more affordable than buying a new unit.
It depends on the unit and on what has worn. These are the things that decide it:
Occasionally a unit is beyond economic repair, for example after severe internal damage. We tell you honestly when that is the case rather than rebuild something that is not worth it.
A flat battery, a worn belt or a poor connection can look like a failing alternator. The battery warning light monitors charging voltage, not just the battery. A bench test removes the guesswork before you pay for the wrong part. These guides help you narrow it down:
Every alternator is stripped, inspected, rebuilt with quality parts, load-tested for correct voltage output and covered by a 12-month warranty. Typical turnaround is 24 to 48 hours. You can fit the unit yourself, or we fit it at our Coventry workshop. See alternator repair in Coventry.
Send the part number printed on your alternator, or a clear photo of it, together with the make, model and year of your vehicle, on WhatsApp 07452 738887 or by phone. We confirm the right unit and quote.
