Expert Motorhome Electrical Repairs in Sydney

Don’t let electrical faults ruin your trip. From flat house batteries to complex 12v wiring issues, our specialist workshop provides fast, reliable diagnostics and repairs to get you back on the open road.

Specialist RV Auto Electricians You Can Trust

Modern motorhomes rely on complex electrical systems to keep you comfortable, safe, and powered up off-grid. When those systems fail, it takes more than a standard mechanic to find the fault.

At Open Road Motorhomes, our Sydney workshop specialises in the unique electrical architecture of motorhomes and campervans. We understand how habitation electrics integrate with vehicle chassis systems, allowing us to accurately diagnose faults that general repairers often miss. Whether you are dealing with a battery that refuses to hold a charge or an inverter that keeps tripping, our experienced team delivers honest advice and permanent fixes.

Common Motorhome Electrical Faults We Fix

Electrical issues can be frustrating to track down. If you are experiencing any of these common symptoms, our diagnostic team can isolate the cause and provide a clear repair plan:

House Battery Not Charging

Whether it is failing to charge from the alternator while driving, or not topping up when plugged into mains power.

12v Lighting and Appliance Failures

Flickering lights, water pumps not engaging, or 12v fridges losing power unexpectedly.

240v Mains Hookup Issues

Safety switches tripping when you plug into a caravan park power pedestal, or specific 240v outlets not working inside the cabin.

Inverter and Battery Management Faults

Error codes on your management screen, or inverters shutting down when under load.

Parasitic Power Drains

Batteries going flat while the motorhome is parked or in storage, even with all switches turned off.

Comprehensive Motorhome Electrical Services

We provide complete electrical repairs, maintenance, and upgrades for all major motorhome brands, including Jayco, Avida, Sunliner, Winnebago, Avan, and Trakka.

12v and 240v System Repairs

We trace and repair wiring faults across both your low-voltage 12v habitation systems and your 240v mains power circuits. From replacing burnt-out fuses and damaged relays to complete system rewiring, we ensure your motorhome meets all Australian safety standards.

Battery Testing and Replacement

Your deep-cycle batteries are the heart of your motorhome. We offer comprehensive load testing to determine the true health of your AGM or lithium batteries. If a replacement is needed, we supply and fit high-quality batteries suited to your specific travel style and power demands.

Battery Management Systems (BMS)

A faulty BMS can destroy expensive batteries. We diagnose, repair, and upgrade battery management systems, DC-to-DC chargers, and solar regulators to ensure your power is being captured and stored efficiently.

Free Camping Upgrades

We don’t just fix faults.

We regularly upgrade motorhomes and campervans to make them more capable off-grid.

If you want to spend more time free camping and less time hunting for powered sites, our team can assess your current setup and recommend the right upgrades for your travel style and budget.

Popular upgrades include:

Lithium (LiFePO4) battery installations for greater capacity and longer cycle life

Expanded solar panel capacity for faster recharging in all conditions

DC-to-DC charger upgrades for more efficient charging from your vehicle alternator

MPPT solar regulator replacements for improved solar harvest

12V system rewiring and load management for cleaner, safer power distribution

Inverter installations to run 240V appliances off-grid

Whether you’re planning a lap of Australia or just want the freedom to stop wherever you like, we’ll make sure your motorhome has the power to back it up.

How Our Diagnostic Process Works

We do not believe in guessing or blindly replacing expensive parts. Our approach to electrical repairs is methodical and transparent:

Initial Assessment

We listen to the symptoms you have experienced and conduct a visual inspection of your electrical setup.

Systematic Fault Finding

Using professional diagnostic equipment, we trace the circuits to isolate the exact cause of the failure, whether it is a degraded cable, a blown component, or a failing battery.

Clear Quotation

Before any repair work begins, we explain the problem in plain English and provide a clear quote for the necessary repairs.

Quality Repair

Our technicians complete the repair using high-quality, marine-grade components designed to withstand the vibrations and harsh conditions of Australian travel.

David

Having left the UK in 2006, I travelled across the other side of the world on my own adventure ending up in Australia in early 2007.

With all my family and friends living in the UK, I had to build my own new network and get into the Aussie way of life.

By accident, I started working in the RV industry selling campervans, motorhomes and caravans to the thousands of adventurous spirits that call Australia home. I soon realized that these people all had the same passionate excitement for life, loved the freedom of exploring the country and were full of wisdom and stories from around the world.

I haven’t looked back and take great pride in being a part of such a life changing experience for the community of travellers that I meet every day.

Phil

“Genuine travel has no destination. Travellers do not go somewhere, but constantly discover they are somewhere else.” – James Carse

To me this quote says it all, it’s the reason why I love what I do.

Travelling is in my blood. I met the love of my life somewhere far from home and ever since we have been seeking new places and meeting new faces with our young family.

Now, together with Open Road Motorhomes, we are helping everyone live the life of their dreams.

 Trustindex verifies that the original source of the review is Google. Fantastic service !! From start to finish. This was our first motor home purchase, so very daunting, but it turned out to be a great experience. We had a full handover experience, explaining every detail of our Jayco Conquest and the do’s  and don’ts. This gave us the confidence to to leave the next day for a 3 day holiday, which was wonderful. Lovely friendly staff and absolutely recommended. Five stars all round 😀👌

 Trustindex verifies that the original source of the review is Google. Nathen and Guy worked a solid five hours on my van this morning. It was a last minute squeeze in job that we thought was going to be simple and quick. But are they ever lol. I just can’t speak highly enough of the whole team. The beautiful lady that made me tea and reassured me, the manager who is clearly so passionate about her job, all of the other people that said hi, kept an eye on my cat, clearly everyone loved their jobs and the people they worked for. I’m a single middle aged well perhaps old now, woman and have come across some really shoddy people that have tried to take advantage but these guys are the real deal. They know 12 v. ! Thank you everyone. Jeannie.

Cherie and I recently purchased a motorhome from Open Road Motorhomes at Glendenning NSW, and our experience with the team has been excellent. What we particularly appreciated was that there was absolutely no pushy behaviour or slick sales tactics. It was simply genuine, friendly people running a good business, providing quality service and offering a great range of both new and second-hand motorhomes. Most importantly, they had the perfect motorhome for us at a price we were happy with. A special mention to Eddie, who spent a considerable amount of time with Cherie and me showing us through the different motorhomes they had available, explaining the various options and answering all of our questions. He listened to us, understood what we were looking for and helped us find the motorhome that best suited our needs. Once we found the one we loved, Eddie took the time to walk us through how everything worked and made sure we properly understood the vehicle. We enjoyed his approach and loved the van they had there so much, that we decided to purchase a motorhome and pay our deposit on the spot. Kelly has also been fantastic to deal with throughout the purchase and settlement process. Communication has been professional and friendly, and the whole transaction has felt straightforward and comfortable. Even our request for a test drive was simple and no problem at all. During the process, the team also identified a crack in the upper rear spoiler that we hadn't picked up ourselves and immediately arranged for it to be replaced before handover. That sort of thing gives you confidence that you're dealing with people who actually care about what they're selling. Buying a motorhome is a significant purchase, and it makes a huge difference dealing with people you feel you can trust. They even guided us for insurance for our new van which was helpful and appreciated. Over the many months Cherie and I spent researching and searching for the right motorhome, we visited and dealt with quite a few dealerships through NSW and Queensland. Along the way we encountered plenty of slick salespeople using the old-school pressure tactics, trying to create urgency or pushing us into making a commitment while we were standing there. At times some of it was annoying and, frankly, almost laughable. There was none of that with Eddie or Kelly. They simply listened, answered our questions and did their best to help us find the right motorhome. We were left to make our own decision without pressure, and we really appreciated that approach. We're now very excited to collect our Jayco RM23 - 4 motorhome and start enjoying it. Thanks again to Eddie, Kelly and the entire Open Road Motorhomes team. Based on our experience, we would happily recommend them to anyone looking for a motorhome.

 Trustindex verifies that the original source of the review is Google. I can’t recommend this Open Road Motorhomes highly enough. After weeks of frustration trying to sell my motorhome through consignment with another dealer in Canberra, dealing with uncertainty, ongoing negotiations and having the agreement ultimately fall through after it had already been accepted, this experience was an absolute breath of fresh air. From my first conversation with Phil, everything was straightforward. He made me a fair offer, explained the process clearly, arranged collection of the motorhome from Canberra, handled all of the paperwork and transferred the funds directly into my account. It was exactly what I had hoped selling a motorhome would be. Having now experienced both consignment and an outright purchase, I honestly wish I’d gone down this path from the beginning. Selling outright removed all the stress, uncertainty and endless back-and-forth, and allowed me to move on knowing everything had been taken care of. If you’re weighing up whether to consign your motorhome or sell it outright, my personal experience is that an outright sale was by far the simpler, more transparent and less stressful option. I wouldn’t hesitate to recommend Phil and the team at Open Road Motorhomes.

 Trustindex verifies that the original source of the review is Google. ⭐️⭐️⭐️⭐️⭐️ We had a wonderful experience with Open Road in Sydney when purchasing our Jayco motorhome. From the beginning, the team was very friendly, helpful and professional. They made us feel comfortable throughout the whole process and were always happy to answer our questions. We had a couple of small issues after purchasing the motorhome, including the antenna and battery/power supply, but Open Road looked after us extremely well. They replaced the battery and fixed the antenna issue without hesitation. We really appreciate their kindness, honesty and excellent customer service. It made a big difference to us, and we would happily recommend Open Road to anyone looking to purchase a motorhome or caravan. Thank you to the whole team at Open Road Sydney for looking after us so well! 🚐❤️

A pleasure to deal with. From my first phone enquiry to driving out with my dream campervan the team at Open Road Motorhomes were fantastic. Without exception, all of them were open, knowledgeable and genuinely caring. If you dream of an escape vehicle, this is the team to talk to. Thankyou Eddie, Kelly and Phil, see you on the road.

Frequently Asked Questions About Motorhome Electrics

Why is my motorhome house battery not charging while driving?

This is often caused by a blown fuse between the vehicle’s alternator and the habitation battery, a faulty voltage-sensitive relay (VSR), or a failing DC-to-DC charger. It can also be due to poor earth connections or the battery itself reaching the end of its lifespan.

Do I need a licensed electrician to work on my motorhome?

Any work involving the 240v mains power system in your motorhome must be completed by a licensed electrician to comply with Australian safety standards. While 12v systems do not legally require a licensed electrician, the complexity of modern motorhome wiring means it should only be handled by experienced RV technicians to prevent fire risks and equipment damage.

How long do deep-cycle motorhome batteries last?

The lifespan of a motorhome battery depends heavily on how it is used and maintained. Traditional AGM batteries typically last 3 to 5 years if they are not regularly discharged below 50%. Lithium (LiFePO4) batteries can last up to 10 years or more, as they can handle deeper discharges and more charge cycles.

Can you upgrade my existing electrical system?

Yes. If you are planning to spend more time free-camping, we can upgrade your system to handle the increased demand. This often includes installing higher-capacity lithium batteries, upgrading the battery management system, and fitting larger inverters to run 240v appliances off-grid.
