Auto Electrical Tullamarine
Won't start, intermittent faults, dashboard warning lights, parasitic drain? Auto electrical is where bad workshops guess and good ones diagnose. We do the latter.
Auto Electrical Repair Without the Guesswork
Modern cars have more electrical complexity than the laptop you're reading this on. Tracing a fault in a vehicle CAN bus network, a body control module, or a wiring harness that's been chewed by a mouse takes patience, the right scan tools, and methodical work. It's also where some workshops give up fast and start replacing parts.
At 6 Garden Dr we approach auto electrical the same way we approach any diagnostic: measure, don't guess. Battery and alternator load testing, parasitic drain tests, multi-meter checks on circuits, scan tool diagnosis with bidirectional control where supported. We trace the actual fault before quoting the fix.
Common jobs we see for Tullamarine, Westmeadows, Gladstone Park and Airport West customers: cars that crank but won't start (fuel pump relay, immobiliser, crank sensor), batteries that go flat overnight (parasitic drain from a stuck-on light or module), alternators that aren't charging properly, dashboard warning lights with no obvious cause, intermittent electrical gremlins, and modern issues like start-stop systems that have failed because the AGM battery is past its limits.
What's Included in Every Car Service
Every auto electrical job at our Tullamarine workshop starts with a proper voltage and amp-draw test, scan tool diagnosis, and a clear explanation of what we've found.
Auto Electrical Work We Handle
From a dead start to a hard-to-find parasitic drain — every part of your vehicle electrical system, diagnosed and repaired at our Tullamarine workshop.
Fault-Finding & Diagnostics
Intermittent faults, dash warning lights, modules talking to each other and dropping out — we scan ECUs, read live data, and trace wiring back to the source. We find the actual fault before quoting parts.
Alternators & Starter Motors
Slow cranking, no-start, or charge light on the dash? We bench-test alternator output and starter draw, rebuild where the unit is sound, and replace only when the core is past it. Battery-drain testing included.
Wiring & Rewiring
Chafed looms, corroded earths, dodgy aftermarket installs — we repair damaged wiring properly with solder and heatshrink, not crimp-and-pray. Full rewires available for older vehicles and project cars.
ECU & Engine Management
Engine management warning lights, misfires logged against specific cylinders, sensor faults — we diagnose the ECU side and the input sensors driving it. Tuning available where it's the right call.
Alarms & Immobilisers
Immobiliser not reading the key, alarm triggering randomly, central locking inconsistent — we diagnose and repair factory systems and aftermarket installs. Key reprogramming and module replacement where needed.
Lighting & Accessories
Driving lights, light bars, reverse cameras, reverse beepers, dash cams — wired in properly with a relay, fuse, and a tidy loom. Existing installs tidied up where the last sparky left a mess behind the dash.
