Work around Wallarah or live on one of its few properties? This sparsely populated suburb is crossed by the M1 and the Motorway Link, and land on the Motorway Link has been rezoned for industry, so the work here is about trucks, utes and highway kilometres more than suburban cars.

Common auto electrical jobs in Wallarah
Wallarah covers about 8 square kilometres with only a few hundred residents. In 2020, land on the Motorway Link here was rezoned for general industry, adding to the employment land around Bushells Ridge and Warnervale.
Jump-starting heavy vehicles
Trucks and heavy plant on the Motorway Link usually run 24V systems, and a flat 24V battery bank can't be safely jumped from an ordinary 12V car. Doing it wrong can damage electronics on both vehicles. Use a 24V jump starter or another 24V vehicle, connect in the correct order, and make the last connection on an engine earth. Our guide on jump-starting safely covers the basics.

Watching the charge on long runs
Utes and vans that spend all day on the M1 and the Motorway Link rely on the alternator. A voltmeter on the dash shows at a glance whether the charging system is working, and a sudden drop warns you before the battery goes flat. If the battery light comes on while driving, our guide on the battery warning light explains what to do.

Breakaway systems on heavy trailers
Heavier trailers with electric brakes need a breakaway system that applies the brakes if the trailer comes off the vehicle. It has its own battery, which needs to stay charged, and a pin switch connected to the tow vehicle by a lanyard. Test it regularly and check the battery charge. Our guide on 7-pin vs 12-pin trailer plugs explains where the charge feed usually comes from.

Light bars and beacons on site utes
Utes working on industrial land along the Motorway Link often carry LED light bars for night work and amber beacons for site access. A light bar draws real current, so it needs a relay, a fuse near the battery and cable sized for the load. Mount it so it doesn't block the headlights or the number plate. Wire the switch so the light bar can't be left on when the ute is parked, or it will flatten the battery overnight.

Wallarah auto electrical questions
Can I jump-start a 24V truck from my car?
No. A car runs a 12V system, and connecting it to a 24V truck can damage electronics on both vehicles. Use a 24V jump starter or another 24V vehicle. Some trucks have a dedicated jump-start point, so check the manual. Always connect the leads in the correct order, and keep sparks away from the batteries.
What is a trailer breakaway system?
It's a safety system for heavier trailers with electric brakes. If the trailer separates from the tow vehicle, a cable pulls a pin that sends power from a small battery on the trailer to the brakes, bringing it to a stop. The battery must stay charged, usually through a feed from the tow vehicle, so test it regularly.
Local tip for Wallarah
If you run a ute or truck out of Wallarah each day, glance at the voltmeter or the battery light as part of your start-up routine. A charging fault caught in the yard is an easy fix. Caught halfway along the M1 with a loaded trailer, it's a tow truck and a lost day.
