I recently had my car's AC fixed at Voltaic, and I couldn't be happier with their service! From the moment I booked the appointment with Tara over the phone, everything was smooth and professional. She made the process easy and ensured all my questions were answered.A big shoutout to Dion, the technician who worked on my BMW. Being a BMW owner himself, he not only repaired the AC efficiently but also kept me informed every step of the way. Dion went above and beyond by showing me the repair process at each stage, which really gave me confidence in their transparency and expertise.It's refreshing to find a garage that prioritizes transparency, excellent communication, and high-quality workmanship.
Thanks Anthony for the great work on the Cub Camper. Honest helpful value based service.
Work done on my car with my aux battery was great and was of very good quality. Shout out to Anthony for doing an excellent job.

Recently had an air conditioner installed on our dog trailer the service and installation from Paul Williams was excellent and nothing was a problem for him to deal with .
I had my Dmax in for a Starlink installation which included a more complex setup of an external router, external antenna, etc. Dion did an amazing job with the installation, going above and beyond with what was requested.Dion and the Voltaic team have been incredibly accomodating, professional and have provided the best service that I’ve received when it comes to auto electrical installations.Would happily recommend Voltaic, Dion and the team for any type of Starlink install and any auto electrical work. Thanks again!
Everyone at Voltaic were very friendly and very knowledgeable about the services I required. I was able to get in within a week of me calling up where i wouldn't have been able to get in until 2025 for the more commercialised companies like ironman 4x4 and TJM. I am very happy with the service they provided. I will be coming back for more work on our 4x4
Highly recommend this company for all your auto electrical work. We had a great technician in Anthony he did an awesome job installing Starlink in our caravan.
I’ve had quite a few electrical jobs done on my car through Voltaic. They do a very good job. They are always friendly and happy to answer any questions you may have. I wouldn’t go anywhere else! Thanks guys
I found Voltaic Auto Electrical after looking for a 12v system for my Ford Ranger over a year ago, i ended up going with one of the battery box setups as i don't require constant power in my tub. The service and quality I received on that initial job has guaranteed them a client for life. I will always go to Voltaic for all my auto electrical work and have been back for tail lights, rear lights, electrical tidying, and no doubt I will be back for more in the future.Big thanks to the team at Voltaic.They also have great merchandise.
Very happy with Voltaic Electrical, all staff very professional & efficient. Wouldn’t hesitate to recommend their work & advice they gave.
My car air-conditioning was blowing warm air, so I wanted it checked before the hot Perth summer arrived. I received fantastic customer service from Voltaic from start to finish. Friendly customer service, honest feedback to advise that due to the age of my car, it might be an expensive repair, speedy diagnosis and repair which ended in happy news - my gas needed topping up and a filter change. I would thoroughly recommend Voltaic Auto Electrical.
The Team at Voltaic pulled out all stops to have our vehicle fitted with a UHF radio and flashing beacon at short notice and no compromise with the quality of work carried out. Excellent service, thank you.
Can't fault them . Great service . Very polite and helpful. I'd recommend them for any of their auto electrical services .
Friendly, helpful staff, fair pricing..Had a UHF radio/aerial installed by someone else that wasn't performing as expected so bought a new one. They took the old one out & put the new one in, in no time! Also grateful that they didn't use the aerial mount provided because it would have damaged my paintwork, and instead found a different mount that worked. I'll have no hesitation in taking my car back here for future installs!
Fantastic service by all the team and particular props to technician Kane. All issues were diagnosed and repaired, in addition to upgrades. He really went above to make sure my car was electrically safe and sound.
Kayne from Voltaic did a great job wiring up my battery to my car and getting everything set up Highly recommend this place they do a good work
Great service easy to deal with.
Was very happy with the workmanship from Voltaic and especially Anthony who completed the UHF install into the Motorhome. Many thanks also for the assistance driving in and out through the gateway as the vehicle was too large to fit into the main workshop area.
Good efficient service

Had Kayne work on my old Daihatsu Rocky he got everything I needed back to better then factory and got me back behind the wheel of my pride and joy. The communication and understanding that Kayne had made having him work on the car, was amazing. I would absolutely recommend anyone to use Voltaic as their team and work ethic is 110% could not have asked for a better job to be done and again Kayne was an absolute pleasure to have work on my car!!!
I was very happy with the standard of service from all staff at Voltaic: from the prompt and thorough responses from Jaimee to my numerous initial inquiries, through to the workmanship with the installation of dash cameras, and explanations by the technician. All staff were professional and patient with my requests and questions. I would recommend this business for dashcam installations.
Can't speak more highly of the service from Voltaic. The reception staff bent over backwards to get my car, which I rely on for work, in at very short notice. I can't thank them enough. A gold standard level of service.
We had an exceptional service here. We were last minute attention to our brakes from Paul who was so helpful. Fixed our problem very speedily and we are very thankful.
Shoutout to Jamie and the team at Voltaic! Their service is top-notch. Highly recommend!
The Team at Votaic were very helpful with short notice for the job required. They have friendly admin staff at the front and were able to assist with getting my car in the next day to have work done. The boys doing the job explained clearly on what was required and when the job would be completed by. Thank You Voltaic
Was very happy with the workmanship from Voltaic and Deon when fault finding my Redarc issues. They were prompt and precise with every detail, and kept me in a constant loop of feedback when required. In my previous roles I would audit businesses and part of this was their workshop. I would be happy to say, I was impressed by the layout and cleanliness of the workshop from an exterior viewing. I would be contacting them again when next in Perth for any auto electrical work I may have.
Very good job installing dash camera good clean install, had to return following day as they failed to reconnect the tail gate switch but only took a couple of minutes so all good. Would recommend for electrical works on your vehicle.
I've used Voltaic before for a big job. Brilliant to deal with, happy to help, sorted my little request on the spot without an appointment.I recommend I recommend I recommend!
We use Voltaic for the Auto-Electrical works in our mine-spec builds & modifications, as well as adhoc repairs, maintenance & servicing. They offer great service, with expert advice, and assist us with prompt turn-arounds as required. We wouldn’t trust our fleet to anyone else!
The Owners and Mangaement are a fantastic team.They attend to the smallest issues and employ extremely accomodating and prompt service at the drop of a hat.I fully recommend Voltaic and the team.5 STAR
My 10 year old Hyundai has had poor aircon for some time and decided to do something about it. Voltaic was recommended by my regular mechanic so I called by late on Friday. They offered to run a diagnostic test then and there and the outcome was they could book me in first thing on Monday. It was all over by 10am when they called. I collected the car with some very cold air flowing and paid my $199 which I was thrilled. The service by all concerned was first rate and the outcome is better than I hoped.I will gladly recommend them to anyone and will very happily return when needed. Thanks to all concerned.

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.
