Common auto electrical jobs in Coolaroo

Coolaroo is about 18 km north of the city, with around 3,200 residents. It has two stations, Coolaroo on the Craigieburn line and Upfield at the end of the Upfield line, and is known for its recycling and waste industries.

Trucks at recycling sites

Recycling and waste trucks around Coolaroo work hard, stopping and starting all day with hydraulics, lifts and lights in constant use. Most run 24V systems, and faults with charging, earth straps and lighting are common. Dust and moisture get into connectors and switches. Regular checks of batteries and earths reduce breakdowns. Our guide on how to use a multimeter on a car covers basic voltage testing.

Beacons and work lights

Vehicles working on recycling and transfer sites often need amber beacons and bright work lights to be seen. Choose LED units rated for the vehicle's voltage, 12V or 24V, and mount them where they won't be knocked by bins or loaders. Wire them through a relay and fuse, with cable heavy enough for the run. Check site rules for beacon colour, placement and when they must be switched on.

Cameras for heavy vehicles

Reversing a truck or loader around a busy yard is risky, and a camera system with a cab monitor helps a lot. Heavy-duty cameras are built to handle vibration, dust and pressure washing. Use quality connectors and route the cable where it won't be crushed by moving parts. Many systems take two to four cameras to cover the sides as well.

Repairing damaged wiring

On both work trucks and family cars, damaged wiring is a common cause of intermittent faults. Chafed insulation, loose connectors and poor repairs from the past all add up. A proper repair uses the right gauge wire, crimped or soldered joins, and heat shrink to seal out moisture. See how to crimp wire connectors for a good technique. Avoid twisting and taping wires, which loosen and corrode over time.

Coolaroo auto electrical questions

Can I fit 12V lights to a 24V truck?

Not directly. A 12V light on a 24V system will burn out quickly. Many modern LED lights are multi-voltage and work on both 12V and 24V, which is clearly marked on the packaging. Otherwise, buy lights rated for 24V. Some trucks also have a 12V converter for accessories, but check its capacity first.

Why do my truck's lights flicker over bumps?

Flickering over bumps usually means a loose or corroded connection, often an earth. On trucks, chassis earths and trailer plug connections are common culprits. Check the earth straps between the cab, chassis and engine, and clean and tighten them. A voltage drop test will show which connection is causing the problem.

Local tip for Coolaroo

If you run a truck or site vehicle around Coolaroo, pressure-wash the chassis regularly but keep the spray away from connectors, switches and the alternator. Then spray exposed connections with a moisture-displacing product. Dust and grime from recycling sites hold moisture against metal, and that's where corrosion and wiring faults start.
