Alternator Testing & Replacement
Battery warning light on, battery going flat repeatedly, or dimming electrics at idle? Your alternator may be failing. We test the charging system accurately and replace the alternator if needed — getting your electrical system back to full health.
The alternator keeps your battery charged and powers your vehicle's electrical systems while the engine is running. When it fails — or starts to fail — batteries go flat, warning lights appear, and electrical systems begin to misbehave. Many flat battery complaints are actually alternator failures in disguise. We test the full charging system — alternator output voltage, ripple, and regulator function — to confirm whether the alternator or another component is the fault. If replacement is needed, we supply and fit a quality unit matched to your vehicle. Walk in for a charging system test. Replacement booked same or next day on most vehicles.

Charging system test
Alternator output voltage, ripple, and regulator performance tested under load to assess charging system health accurately.
Battery condition check
Battery tested simultaneously — a weak battery can affect charging readings and mask or mimic alternator faults.
Fault confirmation & recommendation
Test results reviewed and a clear recommendation made — repair, replace, or investigate further if the fault lies elsewhere.
Alternator replacement
Failed alternator removed, replacement unit fitted and all connections, belt, and tensioner checked before the system is re-tested.
Post-fit charging verification
Charging voltage and system output confirmed correct after fitment, then vehicle returned with full system operating normally.
