Auto electrical diagnostics
Warning lights, intermittent faults, batteries going flat overnight. We scan it, test it under load and show you what we found — not just a guess.
72 Bourke Street, Dubbo NSW · Auto electrical & diagnostics
Auto electrical problems, found and fixed properly.
Macca's Auto Electrical is the Dubbo workshop for the tricky stuff — flat batteries that aren't the battery, wiring gremlins, lights and accessories that won't behave. We find the actual fault, then put it in writing before we start.
- Auto electrical & diagnostics — the whole job, not a sideline
- Scan-tool diagnosis before any guesswork
- A written quote before work starts
- In central Dubbo, on Bourke Street
What we sort
If it's electrical and it's on a vehicle, it's our bread and butter. The jobs that come through the Bourke Street door most weeks:
Starting & charging
Batteries, alternators, starter motors. We test the whole circuit so you're not replacing parts one at a time and hoping the next one fixes it.
Wiring & fault finding
Chafed looms, corroded earths, past “repairs” that caused more than they cured. Traced back to the source and repaired properly.
Lights & accessories
Driving lights, light bars, UHF radios, dash cams and reversing cameras — wired in tidy, fused right and left so it won't rattle loose.
Trailer & caravan wiring
7-pin and 12-pin plugs, brake controllers and breakaway kits. Tested with a load on before you hitch up and head off.
Dual-battery & 12V setups
4WD and touring builds — DC-DC chargers, fridges, inverters and solar input, put together to cope with corrugations.
Marine, farm & fleet
Boats, headers, tractors and farm utes get the same diagnostic approach. Where bringing the machine in doesn't make sense, ask about a call-out around the Dubbo region.
How it works
Auto electrical faults get expensive when parts get thrown at a guess. Here's the order we do it in, every time.
-
Tell us what it's doing
Send the form with your make, model, year and rego, and describe what you're noticing — when it happens and how often.
-
We diagnose it
The vehicle goes on the bench and the scan tool. We find the fault itself, not just the symptom that's showing on the dash.
-
You get it in writing
A quote with the parts, the hours and the total. Nothing else happens until you say go ahead.
-
Fixed and tested
We do the repair, test the circuit under load, and tell you what was wrong and why — so you know it's actually sorted.
Indicative pricing
Every vehicle is wired a bit differently, so these are starting points to give you a feel — not a quote.
- Battery, starting & charging testfrom $60
- Alternator replacement, most vehiclesfrom $420
- Starter motor replacementfrom $380
- Trailer or caravan wiring plugfrom $180
- Driving lights or light bar, wired & fusedfrom $150
Starting points only. The number that counts is the written quote for your vehicle, and no work starts until you've okayed it. Ask us up front how diagnostic time is handled.

Thanks — on the live site this would be on its way to the workshop inbox. This is a concept page prepared for Macca's Auto Electrical, so nothing has actually been sent.
