Auto Electrician Needed — Van Rewire + Audio Install

$10

Lane Cove NSW 2066, Australia

13th Aug 2026

Background: Van came with an aftermarket dual-battery + accessory install already fitted by a previous owner/installer. Ford dealership recently diagnosed: alternator can’t properly charge multiple batteries in the current configuration, a 50A aftermarket fuse had blown, and the setup is “not connected correctly.” Ford recommended a proper DC-DC charger be installed. I don’t fully trust the existing wiring — want a qualified second set of eyes on the whole thing. Scope of work: • Full inspection of existing 12V wiring — batteries, fuses, accessory circuits, lighting • Identify and remove any unused/random/exposed cabling — some appears exposed and I’m concerned about a possible short • Supply and install a proper DC-DC charger unit for the leisure battery • Fix non-working interior lights (some circuits dead, one flickers) • Diagnose an unidentified accessory screen/display currently showing no output This is a work vehicle for my painting business, so it needs to be reliable and roadworthy, not just “good enough.” Please reply with your experience level, whether you handle both electrical safety work and car audio, and your hourly/callout rate.

Nissan Pathfinder R51 (2008) AY93HP I had the car inspected for a pink slip, and all was good apart from the rear brake lights. I replaced the brake light switch, fuse, and right bulb. Now both the left and right lights are working fine. However, the high level light doesn't seem to be getting power so I need this looked at and fixed.

Auto Electrician Needed to Wire Custom Headlights & Ghozt Controller

$300

Woodpark NSW, Australia

13th Aug 2026

I’m looking for an experienced auto electrician or someone confident with automotive wiring to complete the electrical installation of custom aftermarket headlights on my 2013 Volkswagen Scirocco R. I will be physically installing and mounting the headlights myself, so I only need assistance with the electrical/wiring side of the installation. The work involves: * Running the required wire from the headlight/headlight harness to the vehicle’s fuse box. * Connecting the Ghozt lighting controller according to the supplied wiring instructions. * Connecting 12V switched/ignition power, 12V constant battery power, and ground to the controller as required. * Ensuring the indicator connections/controller wiring are correctly configured. * Soldering, heat-shrinking and properly securing/insulating any connections as required. * Testing everything once connected to ensure the headlights, indicators and controller operate correctly. I have the manufacturer’s wiring diagrams and installation documentation, which I can provide. The documentation specifically explains the connections required for the Ghozt controller and headlights. The headlights themselves will already be fitted to the vehicle, so no bumper removal or physical headlight installation is required.

Mobile Auto Electrician: Hardwire Victron Charger: Battery to Grille

$145

The Ponds NSW, Australia

11th Aug 2026

Note: Happy to come to your workshop to save on callout fee if reasonable. Looking for a qualified/licensed mobile auto electrician to install and route a Victron eyelet connector lead with an inline fuse onto the main 12V battery of a 2025 Kia Carnival GT-Line Diesel. Job Details & Scope: Vehicle: 2025 Kia Carnival GT-Line (Diesel) Equipment: Victron Energy fused eyelet connector cable (M8 ring terminals) Goal: Hardwire the eyelet lead to the battery terminals and route the quick-connect plug to a neat, accessible spot behind/near the front grille so the car can be charged on the driveway without opening the bonnet. Key Requirements & Best Practices: 1. Safety First: Remove the inline fuse from the harness prior to installation and reinsert only once all wiring and connections are finalized. 2. Solid Connections: Correctly torque eyelet terminals to battery posts/distribution block without disrupting existing vehicle sensor wiring (e.g., BMS sensor on negative terminal). 3. Protection: Encase the entire wiring run in suitable automotive split-conduit (corrugated tubing) to protect against engine heat, vibration, and sharp edges. 4. Clean Routing: Securely cable-tie the harness along existing factory wiring paths, keeping it well clear of moving engine parts or extreme heat sources. 5. Weatherproofing & Access: Position the quick-connect plug at the front grille so it is easy to reach, securely anchored, and protected from water/road debris when capped. 6. Testing: Verify correct polarity and test voltage at the quick-connect plug once the fuse is reinstalled and test battery charging. Tools & Materials: I will supply the Victron eyelet connector cable (with built-in fuse holder). Please bring your own standard auto electrical hand tools, cable ties, multimeter, and automotive split conduit

Looking for an auto electrician to help cable up the lights on canopy.

Edgeworth NSW 2285, Australia

Auto Electrician Needed – Install Rear Canopy Lights & Check DC-DC Charger Wiring I've recently fitted a new tradesman 4x4 canopy to MR Triton and need the rear LED lights wired up and installed. It looks like a fairly straightforward job, but I'd prefer someone experienced to do it properly. Manual says like hour jib so sure you could smash it out quickly While you're here, I'd also like you to have a look at the wiring for my DC-DC charger. It stopped charging the auxiliary battery after I changed the Anderson plug, so I'm guessing I've done something wrong and would appreciate someone diagnosing and fixing it. Looking for someone with auto electrical experience who has their own tools. Located at Edgeworth Please let me know your experience, availability, and quote. Thanks! 🚙🔧

I have a 1991 landcruiser 80 series, when I plug a charger in the lighter socket it trips the radio and clock that are directly above it on the dash and all three don't work. When there is no charger plugged into the lighter socket the radio and clock work fine. I assume there is a short behind the dash so would like someone to fix it.

Excellent work very happy! Will definitely use again
