Did a schmick job professionally and quickly.
Extremely professional, great service and would and have recommended them reliability and care
Excellent service that made me feel like a person rather than just a job. Am already recommending to anyone who will listen! Thank you!
Very helpful and accommodating staff, highly recommend them
We had a failed tailgate button on our pug 208. It was making my wife and I slightly cranky. I rang several auto electricians and all of them said “take it to a Peugeot dealer”. My experience with dealerships since migrating to Australia has not been a stellar experience. The local Peugeot dealer never bothered to respond.
I called voltaic. They said “sure, we’ll take a look. No promises.”
The team at voltaic fixed the problem pretty quickly! The team also connected an aftermarket reverse camera that I’d bought to our replacement head unit and it works a treat!
My wife is very happy with a boot that is now accessible and having the camera is a boon.
Very happy with the service and the work that was done.
Thank you voltaic 👍
Cheers

Excellent customer service. Good quality work. Thanks guys
Great team. Super helpful and friendly
Smooth and easy process to get the interlock device put in the car. Highly recommend this company for anyone looking to go through the interlock process 🤙🏻
The quality of work completed by Max is outstanding. The detail in the finished product completed has exceeded my expectation. From start to finish dealing from conception of my requirements, including my custom inside tube bracket, the products used by Voltaic. On day of the works Max checked my requirements, including wiring diagrams from OEM and caravan charging requirements. When collecting my vehicle Max even came out and gave me a personal run over the works completed. To top the the whole experience I even won a 12 jaffle Maker!
the camera is very Good and the price was affordable. the quality is phenomenal. they fixed the camera to my car without any labour cost I would recommend to everyone
Big thanks to Tara and the team at voltaic. Really appreciate the work that has been done and no matter the situation or last minute bookings. They will always cater to the customer. Highly recommended 👌
They commented good with me
Exceptional service!
We recently had a light bar fitted to our car by Voltaic Auto Electrical, and the whole experience was fantastic. The service was quick, professional, and top quality. A special shoutout to Kody, who was incredibly informative and showed an amazing work ethic—he really went above and beyond to make sure everything was perfect and explained everything clearly. Highly recommend Voltaic Auto Electrical for anyone looking for reliable and friendly service!
Im a female 4wd owner, I needed to get a new GME antenna installed replacing my existing one. Job was done had one issue as a result which I texted about on Saturday morning. Had a lovely ph call from Jamie this morning when the office was open where they offered to repair.

Excellent customer service, very friendly team. Would highly recommend Voltaic!!
Kayne and Max were so helpful in sorting my battery out as I was stranded in Perth and needed to get home

Thanks for the help you legends
I have been using the team at voltaic Joshua, Paul, Tara and Adam for several years now and the service and professionalism is at the highest level that I have seen. Not only does voltaic have experience in what they do, they are passionate about the industry in which they represent. There is a huge difference in that regard and I won’t use anyone else for my electrical and aircon needs 10/10
These guys (and gals) at Voltaic are seriously amazing. This is your old school customer sercice on steroids. We pulled in with our chevy and off road caravan thinking we would be asked to make an booking and come back which we could not do. We had an issue with our trailer brakes constantly disconnecting. They sorted it out for us right there and then. So happy ! Thank you very very much !
What a fabulous company! Their growth is definately for a reason and it has in no way changed the quality of service. Chipper is so helpful and Dion got the job done with a minimum of fuss. Kayne attended to several different vehicles in our fleet and deserves all the praise I can bestow. What a patient and professional young man. Took his time to explain and teach me about some basics. Was still mindful of timing so I was not overcharged. 10/10 recommend this company. I will most definately be using them in the future.
Can't possibly overstate the service and value for money. They completely undersold and over delivered! Great company, friendly, helpful, extra mile stuff. I will go to them first whenever I have a need in the future. Wish there were more stars.
Super friendly staff, great service and good quality work
I recently visited Voltaic in Welshpool to have a lightbar fitted to a company Toyota RAV4 Hybrid, and I couldn’t be more impressed with the service. From the moment I walked in, the atmosphere was welcoming — the staff are not only friendly and approachable, but it’s also great to see how well they interact with each other, creating a positive and professional vibe in the office.

The team are incredibly knowledgeable and take the time to clearly explain all your options, ensuring you feel confident about the work being done. They’re also very detail-oriented in their approach, which really shows in the quality of the finished job.

Despite the RAV4’s notoriously poor build quality at the front end — with flimsy plastics that could have made the install tricky — the Voltaic team handled it effortlessly. They cleverly mounted the bar behind the grille and secured it to the sturdier crash bar, making the install both neat and durable. This not only looks great but also keeps the lightbar safe from potential “carpark bandits.”

On top of their professional service, their pricing is very reasonable. The site even has a café and some comfy couches inside, which makes waiting around far more pleasant.

Voltaic are also fleet and mining certified, making them an easy recommendation for both individuals and businesses needing auto electrical or air-conditioning services.

Highly recommended — the team at Voltaic really make it a walk in the park, also Special shout out to Dion.
Service from the whole team was exceptional from the ladies at reception through to the technicians who fitted our dual battery system nothing was to much trouble and I am very satisfied with the finished job Thanks Team
It’s all about the Vibe.
When I walked into a showroom I felt the positive energy straight away.
The staff were super helpful and everyone working there looked happy and enjoying themselves.
You know if it’s a mechanical or electrical upgrade to your vehicle you just know that vibe/energy is going transfer into your pride and joy.
I highly recommend Voltaic Auto Electrical
I pick up my 79 series landcruiser yesterday. Kane worked on my vehicle, and I can say that he went above and beyond.He was professional with his workmanship and customer service,definitely a asset to Voltaic.
The work was neat and exactly how I wanted it. 100% I would recommend Voltaic. Thanks for doing such a awsome job Voltaic 👍👍👍👍👍
Excellent friendly staff
My experience with Voltiac was very positive. Their quote was fair and competitive. I got to speak to the electrician who did the job both at the start and at handover. I was able to ask all my questions. If the electrician was unsure about something he consulted with his colleagues. Everything was done as requested. Office staff were also very prompt and professional.
Very professional with a very high level of customer service
had a dual battery installed on my hilux, booking process was easy and quick reply’s going back and forth choosing a date etc. dealt with Kody (?) when i dropped the car off and the communication was thorough from that point until pickup. very neat work, highly recommend
I am really happy with the service at Voltaic.They squeezed me in without an appointment so that I was able to pick up my caravan. Anthony did such a great job, I felt confident in bringing my car back to get all the other electrical issues sorted. Everybody was so pleasant and couldn't do enough to help me out. Thanks everyone at Voltaic
Voltaic are really the go to people their services from the front counter to the workmanship is just top quality, the way the explain the works and keep you in the loop, can not recommend this business enough.

Thoroughly recommend 👌

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.
