Alternator
& charging check

If your battery keeps going flat — even after replacing it — the problem is usually the charging system. We test the alternator, regulator and wiring, and replace the alternator on the spot if it’s failed.

About this service

Your battery is only as good as its charger

While the engine runs, the alternator recharges the battery and powers everything electrical. When it fails, the car runs on battery power alone until it goes flat — often mid-trip.

We measure alternator output under load, check the drive belt and wiring, and look for parasitic drains, so we find the real reason your battery isn’t staying charged.
