If you are looking for a quality service and product I would highly recommend using Voltaic !! For service, efficiency, industry & product knowledge the team down at Voltaic are second to none!! I have to do a special thank you to Tara for sourcing product information and getting the quotes to me in record speed with accuracy!! Absolutely bang on!! And a massive thank you to Max for the installation and customer service that he gave me, absolutely smashed it out of the park with such a clean fit out and took the time to run through the whole job with me and delivered it on time and nothing short of perfection!! Thanks again to the Voltaic team I will be running our whole fleet through them for sure!!
Voltaic (in conjunction with Elite Tune) completed an outstanding mine spec upgrade of my dual-cab LandCruiser. High quality work, very tidy job all round and will be using them again. Would recommend.
OMG such a professional install in a timely fashion by the nicest crew I’ve met. I had planned on doing my electrics myself but honestly so stoked with these guys that I’ll just leave it to these pros.
Went to Voltaic to have a 2-way fitted — awesome workshop and staff. I was informed there was some very dodgy wiring from the previous second-battery installation: no fuses on some circuits, spaghetti wiring to auxiliary outlets, exposed wires on joins, and a long list of other issues.

Following their excellent advice, I went ahead with the repairs, and the finished job was absolutely brilliant and professional. The team went above and beyond my expectations.

If you want a job done properly, look no further.
Did a schmick job professionally and quickly.

What Does a Car Diagnostic Tell You

Our advanced diagnostic tools and expert technicians can identify and resolve issues across a wide range of systems, including:

  • Lighting faults – interior and exterior.
  • Dashboard fault codes – those cryptic error messages.
  • Air conditioning issues – because no one wants to sweat it out.
  • Starter motor problems – that dreaded click with no start.
  • Intermittent electrical faults – the sneaky glitches that come and go.

How Do Car Diagnostics Work?

  1. Initial Consultation: Tell us what you’ve noticed; warning lights, unusual behaviour, or strange sounds.
  2. Diagnostic Scan: Using the OBD port, we connect our diagnostic scanner to your car’s system. This gives us a detailed report of fault codes and potential issues.
  3. Analysis and Interpretation: Our skilled technicians analyse the results to pinpoint the root cause. We dig deeper when needed, as fault codes are just the starting point.
  4. Discussion and Recommendations: We explain the findings in plain language and outline the next steps, including potential repairs or further testing if necessary.
  5. Repairs and Resolution: With your approval, we’ll fix the issues using high-quality parts and expert workmanship.
  6. Final System Check: After repairs, we perform a final scan to ensure everything is running smoothly and your car is back to peak performance.

FAQs

What is a car diagnostic test?

An auto diagnostic scan uses advanced tools to connect to your car’s On-Board Diagnostics (OBD) system. It retrieves fault codes and provides detailed insights into potential issues with your vehicle.

Do I need to book in advance?

While we recommend booking to secure your spot, we can often accommodate walk-ins depending on our schedule. Call ahead to check availability for the day.

What happens after the scan?

After the scan, our technicians will review the fault codes, explain the findings in plain language, and recommend the best course of action for repairs or further testing.

Can you fix the problems you identify?

Absolutely! Once we identify the issue, our skilled auto electricians will perform the necessary repairs using high-quality parts and expert workmanship.

Will a diagnostic scan damage my car?

No, the scan is completely safe and does not affect your vehicle or its warranty. It’s simply a tool to retrieve information from your car’s computer systems.

What if my car doesn’t have a warning light?

Even if no warning light is on, a diagnostic scan can still uncover hidden issues, reset service interval lights, or help identify the cause of poor performance or fuel efficiency.

Is my car compatible with your diagnostic tools?

Most vehicles manufactured after 1996 are compatible with our diagnostic equipment, as they come with an OBD2 port. If you’re unsure, contact us, and we’ll confirm for you.

How accurate is a car diagnostic test?

A car diagnostic test is highly accurate in identifying fault codes and pinpointing problem areas within your vehicle’s systems. However, the diagnostic tool only reports issues detected by your car’s sensors—it doesn’t always reveal the exact cause of the fault. That’s where expertise comes in.

At Voltaic Auto Electrical, our experienced technicians interpret the fault codes and use their skills to uncover the root cause of the issue. By combining advanced technology with hands-on expertise, we ensure a thorough and precise diagnosis every time.
