These guides are written for the way vehicles are used in and around Perth: the heat, the storms, the salt water and the weekends away. Each one explains how things work, what goes wrong and what to do about it, whether you’re doing the job yourself or booking an auto electrician.
Car batteries in Perth heat
Why batteries die sooner in Western Australia, how to test one, and how to choose and look after a replacement.
Storm season electrical checks
Lights, wipers, drains and batteries before the storms, and what to do if your vehicle gets wet.
Boat trailer wiring
7-pin wiring, why salt water kills trailer lights, and how to set up a boat trailer properly.
Dual battery and caravan setups
DC-DC chargers, AGM vs lithium, cable sizing and fusing for trips to Straddie, Moreton, Bribie and K’gari.
Ute and fleet fit-outs
Beacons, work lights, cameras, inverters and second batteries, wired safely and the same across a fleet.
Choosing an auto electrician
Mobile or workshop, specialists, licences, questions to ask and how to compare quotes.
