Signs You May Have an Electrical Problem

Electrical faults can affect almost any system in your vehicle. These are some of the most common signs that something needs attention:

Battery warning light or frequent flat batteries

If your battery keeps going flat or the battery warning light is on, the issue may be with the alternator, charging system, or a parasitic drain rather than the battery itself.

Lights flickering or not working

Intermittent or failed lighting — headlights, indicators, interior lights — often points to a wiring fault, blown fuse, or failing switch that needs proper diagnosis.

Electrical accessories behaving erratically

Windows, central locking, or other accessories that work intermittently or have stopped working entirely are common signs of wiring, motor, or control module issues.

Vehicle won't start or starts intermittently

A no-start or intermittent start condition can be caused by a faulty starter motor, ignition switch, immobiliser issue, or wiring fault — not always a flat battery.
