Auto Electrical in South Africa

Auto electrical work is diagnostic work first and parts second. Typical symptoms are a car that will not crank, a battery that keeps going flat overnight, dashboard warning lights that come and go, windows or central locking that stop working, or an immobiliser that refuses to recognise the key. A good auto electrician will measure rather than guess, testing charging output, voltage drop and parasitic drain before condemning a part. Rodent damage to wiring looms is common in South Africa and is often the real cause of an intermittent fault that a parts swap will never fix. Alternator and starter motor work can often be rebuilt rather than replaced, which is meaningfully cheaper on older vehicles. Modern cars add complexity because control modules talk to each other on a data bus, so a fault in one place can produce warnings in another. Expect to pay a diagnostic fee, and ask whether it is credited against the repair if you go ahead.
