Auto Electrical Repairs & Diagnostics

Modern cars run on dozens of computers, sensors and kilometres of wiring. When something electrical goes wrong, it can be almost impossible to pin down without the right equipment and experience. That's exactly what Randwick Auto Electrics has specialised in for over 30 years.

Auto Electrical Repairs & Diagnostics

From a flat battery that won't hold charge to an intermittent fault that only appears on a rainy morning, our auto electricians methodically trace the problem back to its source — then fix it properly the first time.

Electrical faults we repair every day

  • Charging system faults — alternators, batteries and voltage regulators
  • Hard starting, no-start and intermittent starting problems
  • Dashboard warning lights and electronic fault codes
  • Power windows, central locking and keyless entry
  • Headlights, tail lights, indicators and interior lighting
  • Wiring repairs, short circuits and parasitic battery drains
  • Cruise control, power seats, wipers and electric mirrors

How our diagnostic process works

We start with a computerised scan of your vehicle's modules to read stored fault codes, then back that up with hands-on testing — multimeters, oscilloscopes and wiring diagrams specific to your make. This stops the all-too-common 'replace parts until it works' approach and gives you an honest, fixed-price quote before any repair begins.

Serving Randwick, Bondi, Coogee, Maroubra and the wider Eastern Suburbs, our team is ready to help. Get in touch or call 02 9398 7888 to book your car in.

Frequently Asked Questions

My car has an electrical fault that comes and goes. Can you find it?

Yes — intermittent faults are our speciality. We use data logging and live monitoring to capture the fault as it happens, rather than guessing. Bring it in and describe when it occurs.

Will replacing my battery fix a charging warning light?

Not always. A charging light often points to the alternator or wiring rather than the battery itself. We test the whole charging system so you don't pay for parts you don't need.

Do you repair wiring or only replace whole looms?

Wherever it's safe and reliable, we repair the specific damaged section rather than replacing an entire loom — saving you money while restoring full function.
