Second cars, school runs and quiet alternator faults
Many Worcester Park households run two cars, and the second one often does very little: a school run to one of the local primaries, a weekend trip to Cuddington Recreation Ground or Hogsmill Open Space, then a few days on the drive. It's a hard life for a battery and a poor way to spot a failing alternator. A small drop in output or a failed diode might never show on those short trips, but the battery quietly loses ground each time until the car won't start.
Main-road driving is slow too. Central Road is single-carriageway with bus stops and crossings, and the North Cheam crossroads with the A24 London Road is a busy signalised junction. Heading down Stonecot Hill in the morning queue, the engine spends a lot of time at idle with the heater and lights on, which is exactly when an alternator's weakness shows. If the lights dim at the lights, or you hear a whine that rises with engine speed, it's worth getting checked before it strands you somewhere inconvenient.
Our testing covers the whole system. We check the battery's health, the alternator's output at idle and under load, and the belt, tensioner and pulley. We also test for a parasitic drain while the car is locked, because a car that goes flat while parked isn't always an alternator problem. You'll get a written quote before anything is replaced, and alternators are OE-specification with a new auxiliary belt.
The route is Cheam Common Road to the North Cheam crossroads, Malden Road to Cheam Village, then the A232 through Sutton to Carshalton and the B277 into Hackbridge, about 6 miles. With a failing alternator that's a long way, so collection is often the better option. Our 3-month workmanship warranty covers the repair, and most cars are ready the same day.
