Auto electrical work is the half of the trade the business is named after. Wiring, modules, sensors, charging faults and the intermittent problems that other workshops hand back unsolved.
Intermittent electrical faults are the ones worth bringing to a workshop that does this daily. They are frustrating precisely because they are not present when the car is on the hoist, and finding them is a process rather than a guess.
Electrical diagnosis is deductive, not a matter of reading a code and replacing the part it names. A code tells you which circuit reported a problem; it does not tell you whether the component, the wiring, a connector, a supply, an earth or the module itself is at fault.
We quote after we have looked at the vehicle, because an honest number needs the actual fault rather than a description of it. What moves the price on this kind of work:
You get the number before the work starts, and nothing extra happens without you approving it first.
European, Asian, Australian and American vehicles — passenger cars, 4WDs, utes, vans and light commercials, for private owners and fleets.
If your vehicle needs something we are not equipped for, we will tell you rather than have a go at it. That is not a common outcome, but it is the honest answer when it happens.
Workmanship and parts are covered. The specific period depends on the job and on the part supplier's own warranty, so the terms that apply to your repair are set out on your invoice — ask us to walk you through them before you approve the work if you would like it clear up front.
This sits alongside your rights under Australian Consumer Law, which apply regardless of what any warranty document says.
Most often a parasitic draw — a module, relay, light or aftermarket accessory staying awake when the car is off. It can also be a failing alternator that is not fully recharging, or a battery near the end of its life. A parasitic draw test identifies which.
By measuring the current the vehicle is still drawing once it has gone to sleep, then isolating circuits one at a time until the draw disappears. On modern vehicles this requires waiting for the modules to actually shut down, which is why the test takes time rather than minutes.
Because something in that circuit is drawing more current than it should — usually a short to earth from damaged wiring, a failing component, or a chafed loom. Fitting a larger fuse is dangerous: the fuse is protecting the wiring, and a bigger one lets the wiring become the fuse.
Often, yes — that work makes up a fair share of what comes through the door. Bring any diagnostic paperwork you have; knowing what has already been tested and replaced saves repeating it.
It shows what a circuit is doing over time rather than an averaged value, which is how you catch brief dropouts, noisy sensor signals, and communication faults that a multimeter or a scan tool will read as normal.
