FAQs
What does a 4WD auto electrician do?
A 4WD auto electrician installs, diagnoses, and repairs the electrical systems that power your accessories and upgrades—like dual batteries, spotlights, UHF radios, and trailer brakes. We make sure everything runs safely and reliably for touring, towing, or off-roading.
How much does 4WD auto electrical work cost in Perth?
Dual battery systems are measured by the battery’s Amp-hours (Ah), which range in capacity depending on the battery. The length of time a dual battery system can run your fridge is determined by the current draw of the complete system, including the fridge. The current draw can change in different environments but, as a base line, a 100Ah battery will run a standard 30L fridge for roughly 12-24 hours.
Do I need a dual battery system for my 4WD?
If you run accessories like fridges, lights, or inverters, a dual battery system is essential. It powers your gear without draining your main battery, keeping you powered off-grid for longer. You can learn more on our dual battery installation page.
How long can I run my fridge on a dual battery system?
Dual battery systems are measured by the battery’s Amp-hours (Ah), which range in capacity depending on the battery. The length of time a dual battery system can run your fridge is determined by the current draw of the complete system, including the fridge. The current draw can change in different environments but, as a base line, a 100Ah battery will run a standard 30L fridge for roughly 12-24 hours.
Can you install extra lighting or spotlights on my 4WD?
Absolutely. We install LED light bars, driving lights, and work lights with neat, hidden wiring and weatherproof connections. Check out our car LED lighting page.
What’s the best way to power my fridge or accessories when camping?
A dual battery system or power management setup is ideal. It gives you reliable 12V power to keep your fridge and devices running overnight without flattening your starter battery.
Can you install UHF radios for touring and off-road trips?
Yes. UHF radios are essential for convoy travel, emergency comms, and off-road coordination. We install fixed or handheld units, antennas, and mounts—see our UHF radio installation page.
What distance should I get on my UHF?
UHF radios vary in transmission power but most quality vehicle-mounted UHF radios generally have around 5 watts of power. A 5-watt UHF radio with a good 6db antenna will give you a range of 5km to 10km.
Can you fit electric brakes for towing my caravan or trailer?
Yes. If your trailer weighs over 750kg, you’ll need an electric brake controller. Our electric brake controller installation service keeps your towing setup safe and compliant.
Is there a warranty on your fit-out services?
Yes, we offer a warranty on our fit-out services, covering both the materials used and the workmanship. The terms and duration of the warranty vary depending on the services provided. For detailed warranty information, please reach out to us directly.
