About O'Brien Auto Electrics

We are Perth’s truck and road transport specialist auto electricians, with decades of experience working on heavy vehicles, transport fleets, and specialised equipment across Western Australia.

Since 1978, our team has built extensive hands-on experience working directly with OEMs, dealerships, and major fleet operators. We specialise in brands including Volvo, Western Star, Mack, and Freightliner, with deep knowledge of their electrical systems, diagnostics, and common fault patterns developed through years working inside dealer networks and factory-supported environments.

From complex diagnostics and electrical fault finding through to repairs, fit-outs, and fleet maintenance, we understand the demands placed on heavy vehicles and the importance of getting them back on the road quickly and reliably. Our workshop and field service team work on everything from prime movers and rigid trucks to heavy equipment and specialised fleet vehicles.

Customers trust O’Brien Auto Electrics because we combine old-school experience with modern diagnostic capability. Many of the problems we solve are the jobs others have already struggled with — and we pride ourselves on practical solutions, honest advice, and workmanship backed by decades in the industry.
