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

Erika Pintegne

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.

Colin Waddell

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.

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.

David Spray

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

Ashley Armstrong

It’s all about the Vibe.
When I walked into a showroom I felt the positive energy straight away.

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

The work was neat and exactly how I wanted it. 100% I would recommend Voltaic. Thanks for doing such a awsome job Voltaic 👍👍👍👍👍

David Eccles

Excellent friendly staff

Peter Lee

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.

Andrew Anderson

Very professional with a very high level of customer service

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.

Kevin Patten

I recently returned to Voltaic Welshpool to have a few upgrades to my Landcruiser 200 series after a great experience having a new GME XRS-370C CB radio installed. This time had a Headlight upgrade, solar panel installed on rhino rack plus a Gator Dash Cam installed. From booking through Jaimee at reception to Max doing the installation the whole process was very friendly and professionally done. Great communication throughout the whole process delivered the end result being a very satisfied customer. I highly recommend the Voltaic team and also make mention of the great cooperation with the Elite Tune team who also did some great work at same time & place. Congrats to you guys.
Cheers Kevin Patten

Great front line reception staff

Paul Gummer

Took in my first company ute for a mine and fitout. Great service, took their time, quality workmanship, explained everything and completed a good walk down after. Will use for each of my fit outs.

Highly recommend

Robyn Cornwell

Dion fitted dual battery, radio and power outlets for solar blanket and fridge to our Prado. Very happy with the professional service, discussion of options and fielding questions post installation. Thanks

Jason V

I haven't had the pleasure of using Voltaic's services, but my review is solely based on my interaction with one of their staff.

Vince rang me to let me know that a courier dropped off a package for me. They had dropped it off to them instead of where my office was, a couple of buildings further up the road.

Vince was courteous, very professional and was happy to hold on to the parcel for me.

I was very impressed by Vince. His honesty, integrity and attitude to doing the right thing is truly admirable. If Vince exemplifies Voltaic's company philosophy and approach to interactions with the general public, I will definitely look to them to get work done on our fleet vehicles.

Shane Yaxley

Highly recommend this company there was no problems in squeezing us in before our Easter holiday. Kayne the technician working on our landcruiser was top notch,very informative and spot on with his diagnosis and phone manner was impeccable 👌

Stefan Lam

Booked in to have a chat with Kody, went through ideas and plans for a dual battery set up. He was very knowledgeable and had a a good plan on how to execute my idea.
When picking up the van the work done was everything we had discussed, the work done was spot on and to a high standard.
This is the second time going with Voltaic and will be back for more work in the future!

Craig Missen

Daniel Murphy

Great experience with Voltaic all the way from start to finish. Jamie and Tara were very helpful with quotes, pricing and ordering.

I've been coming here to Welshpool for a while now with my FJ Cruiser and i am really happy with them. A decent sized business, with a large staff, more than one shop and a highly professional and organised operation, yet still really friendly and interactive. They are not the cheapest mob in town, but their costs are fair and reflect in the quality of their work.
Today i saw Tara at the front desk who was lovely and very helpful, as well as knowledgeable and young fella Max, who is a rippa! See you next time. JT from Kalamunda.

Tony Butler

Laurence James

How Long Does a Car Diagnostic Test Take?

A standard engine diagnostic scan usually takes 15–30 minutes, but the time can vary depending on the complexity of the fault and any additional testing required.

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?

Initial Consultation: Tell us what you’ve noticed; warning lights, unusual behaviour, or strange sounds.
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.
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.
Discussion and Recommendations: We explain the findings in plain language and outline the next steps, including potential repairs or further testing if necessary.
Repairs and Resolution: With your approval, we’ll fix the issues using high-quality parts and expert workmanship.
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.
