Battery Light On? Alternator Fixed. At Home or Workshop.

They do the same job — charging your battery and powering your car's electrics while the engine runs — but work differently. Alternators are fitted to most modern cars (post-1970s) and produce AC current converted to DC. Generators (dynamos) produce DC current directly and are found on older vehicles and some trucks. We repair and replace both.

Cost varies significantly by car make, model, and whether repair or replacement is needed. WhatsApp or call us with your car details for an instant quote. We always provide a full parts-and-labour price before starting — no estimates that change mid-job.

Often yes — and we always try repair first. Common repairable faults include worn brushes, a failed voltage regulator, bad rectifier diodes, or worn bearings. Repair is significantly cheaper than replacement. Our free diagnosis confirms which route is needed — you won't be pushed into a replacement you don't need.

The symptoms overlap, which is why a proper test is essential. A quick guide: if jump-starting works but the car dies again shortly after — it's likely the alternator not recharging the battery. If your car has always been hard to start even with a good charge — it may be the battery. Our free voltage and load test gives a definitive answer in minutes.

Yes — a failing alternator can overcharge or undercharge your battery, drastically shortening its life. Overcharging (above 14.8V) boils the battery acid. Chronic undercharging causes sulphation. If you've had to replace your battery more than once in two years, a faulty alternator may be the real culprit.

Absolutely. Our mobile service is designed exactly for this situation. Call or WhatsApp us with your location — we'll send a mechanic to diagnose the charging fault on-site and carry out the repair or replacement at your location. No tow truck needed in most cases.

For most cars, alternator replacement takes 1 to 2.5 hours. Some European vehicles with tight engine bays (BMW, Audi, Mercedes) can take longer. Repair-only jobs (brushes, regulator) are typically faster — under an hour at the workshop. We'll give you a realistic time estimate when you book.

We always inspect the drive belt as part of the service. If the belt is worn, cracked, or glazed, we recommend replacing it at the same visit — it's much cheaper than a separate call-out later. A broken alternator belt stops your car charging immediately and can also disable power steering and cooling on some vehicles.

Yes — all work comes with a workmanship warranty, and replacement alternators include the manufacturer's parts warranty. If anything related to our repair fails within the warranty period, we'll fix it at no additional cost. Ask us for specific warranty terms when booking.
