Our Auto Electrical Process

Here’s how we make your auto electrical experience smooth. From when you book with us to when you drive away, we focus on making the process straightforward and stress-free. Our Mackay auto electricians combine years of hands-on experience with the latest diagnostic tools, handling every step with precision and care.


  • Initial Assessment & Diagnostics: When you bring your vehicle in, our team starts with a full diagnostic scan, covering systems like the ECU, EMS, EFI, ignition, sensors, alternator, and more. That helps us precisely identify the issue—whether it’s a starter fault, wiring problem, or sensor glitch—instead of just guessing.
  • Clear Quotation & Honest Options: Once we’ve found the issue, we discuss the results with you—no confusing jargon—just plain language. We’ll give you upfront pricing and, when possible, options (like repair vs. replacement) so you can make the choice without stress or surprise billing.
  • Skilled Repairs, Installation & Final Checks: After your go-ahead, we get to work. Our technicians, trained regularly, handle everything with care—repairs or installations. Whether it’s tackling starter systems, batteries, brake controllers, lighting, or air conditioning, everything gets done right. We finish with a road test or rerun diagnostics to ensure your vehicle is safe, functional, and ready for the road. And because we value honest service, there won’t be any hidden fees.

Frequently Asked Questions 

  • HOW DO I KNOW IF MY CAR NEEDS A NEW STARTER MOTOR?

    If you are having trouble getting your vehicle to turn over but your battery is in good condition, this could indicate a starter motor problem.

  • HOW CAN I TELL IF THERE IS A PROBLEM WITH MY ALTERNATOR?

    If you notice the battery light coming on while you are driving, this can indicate an issue with the alternator.

  • THERE IS A CLICKING SOUND WHEN I START MY CAR; WHAT IS THIS?

    This noise is often the result of a dirty or corroded battery terminal. Battery terminals should be kept clean, and you can also apply a thin layer of petroleum jelly to them to prevent corrosion.

  • CAN I JUMP-START MY VEHICLE SO THE ELECTRICS DON'T GET DAMAGED?

    Yes, it is possible to jump start a vehicle safely without damaging the electronics. However, modern cars have complex computer systems, and unless you are sure that the battery is flat and the problem is not due to an electric fault or an internal battery fault, then it is best to call the experts to diagnose your problem to ensure you will not sustain any damage to your electric system.

  • DO YOU STILL HAVE TO TOP UP YOUR CAR BATTERY WITH WATER?

    Yes, if you notice the fluid level in your car battery is low, it should be topped up with water to maintain the electrolyte levels in the battery. If you need to top up your battery frequently, this could indicate faulty wiring or alternator problems.
