How can we help?
Auto Electrical Darwin
12V & vehicle electronics · Winnellie, Darwin
Dual batteries, DC-DC chargers, lights, UHF, cameras, car audio and the wiring faults that come with Top End heat and dust. Cars, utes, 4WDs and trailers, at our Winnellie workshop.
We’re an electronics workshop, not a mechanic. We repair the module or head unit rather than swap it, and don’t do engines, air-conditioning or roadworthy inspections.
12V and 24V work on cars, utes, 4WDs and trailers.
Dual battery and DC-DC systems
Second battery in the tray, under the bonnet or in the canopy, charged properly from the alternator and solar. Redarc, Victron, CTEK and similar. Lithium or AGM, sized for your fridge and your trips.
Canopy and touring fit-outs
Fridge circuits, lighting, USB and 12V outlets, water pumps, inverters and Anderson plugs, wired with correct cable sizes and fuses so nothing melts on the Stuart Highway.
Lighting
LED light bars, driving lights, work lights and camp lighting, switched and fused properly. Spotlight wiring that doesn’t flicker and doesn’t blow fuses.
UHF, dash cams and reversing cameras
UHF radios and antennas, dash cams hard-wired so they don’t flatten the battery, and reversing or trailer cameras on the tow vehicle.
Car audio
Head unit installs, amplifiers, subwoofers and speaker wiring, plus repair of the units themselves when they stop powering up. See electronics repairs.
Trailer and tow wiring
7-pin and 12-pin plugs, Anderson charge lines, electric brake controllers and breakaway systems, wired and tested with the trailer connected.
Wiring faults and flat batteries
Something drains the battery overnight, lights that work sometimes, a fuse that keeps blowing, rodent damage, corroded earths. We measure it rather than guess.
Module and board repair
Body control modules, dash clusters, window and light controllers, head units and chargers repaired at the component level when a replacement is dearer than the car deserves.
Bring the vehicle in. We test. You decide.
- Book or drop in
Fit-outs are best booked so we can order parts. Faults can be looked at on a walk-in basis, Monday to Friday 9am to 5pm at 4/143 Coonawarra Rd, Winnellie.
- We test it
Free diagnosis. We measure the fault or scope the install and give you a written quote for parts and labour.
- Done and tested
Everything is fused, labelled and tested under load before you drive off. You get a note of what was fitted and where the fuses are.
What it costs
You approve the total before any chargeable work starts.
Common questions
Are you a mechanic?
No. We do the electrical and electronic side: batteries, charging, wiring, lighting, comms, audio and the control modules. Engine, air-con, brakes and roadworthy inspections are a mechanic’s job.
Do you install dual battery systems?
Yes. Under-bonnet, tray and canopy installs with DC-DC charging and solar input, using Redarc, Victron, CTEK and similar gear, sized for what you actually run.
My battery goes flat overnight. Can you find why?
Yes. We measure parasitic drain circuit by circuit until we find the culprit, usually an accessory never wired to switch off.
Can you fix my head unit instead of replacing it?
Often. We repair head units, amplifiers and subwoofer amps at the board level. If it isn’t economic we tell you before you spend anything.
Do you wire caravans and camper trailers too?
Yes. That’s a big part of what we do. See the caravan and campervan wiring page.
Do you do 240V work?
We work on the 12V and 24V side and on the electronics. Mains wiring in a shed or a house is a job for a licensed electrician.
Darwin, Palmerston and the rural area.
Most vehicle work happens at the Winnellie workshop. For vehicles that can’t be driven in, we come to you across Darwin, Palmerston, Howard Springs and Humpty Doo.
Before you come in
Tell us what you run and where you go. Fridge size, how many days between power, and what you tow decides the battery and charger, not the brochure.
Diagnosis is free. You get the quote in writing before any chargeable work starts.

We’re the end unit of the 143 Coonawarra Rd complex, on the Mataram St corner — the same block as Top End Car Rentals and Campervan Hire.
Come around to the Mataram St side and park on the hardstand out the front.
Campers and caravans: under 12 m only, and by booking — book a time and wait for the confirmation before you drive over, so the bay is clear when you arrive.
Searching the street address in Google drops you at the wrong building on Coonawarra Rd. Use the map link below — it is pinned on our door.
