Road trains and 24-volt systems
Heavy trucks and many buses run 24 volts, with banks of batteries and bigger charging systems than any car. Road trains add multiple trailers, long cable runs and a lot of lighting, and every connection along the way is a possible fault point. An auto electrician who regularly works on heavy vehicles will have the equipment and know-how to trace problems through the whole combination.
Typical heavy vehicle jobs
- Charging, starting and battery bank faults
- Trailer plug, cable and lighting repairs on multi-trailer combinations
- Air conditioning electrical faults in truck cabs
- Beacons, work lights, cameras and radio fit-outs
- Electrical repairs on earthmoving and construction machinery
Heat, humidity and the wet season are hard on heavy vehicle wiring. Corrosion builds up in plugs and connectors, and water can get into junction boxes after monsoon downpours. During the dry, dust from unsealed roads causes its own problems. Regular inspection and cleaning of trailer connections prevents many roadside failures.
Workshop or depot
Big jobs generally need a workshop with heavy vehicle access, and much of Darwin’s transport and industrial activity sits around Winnellie, Berrimah and Yarrawonga. Many truck auto electricians also come to depots and yards to diagnose faults or carry out smaller repairs, which can save moving a truck that is not running.
Booking tips
Tell the auto electrician the make, model and year of the prime mover or rigid, how many trailers it pulls and how they connect, and exactly what is wrong. Note warning lights and whether the fault is constant or intermittent. For fleets, give a list of vehicles and when they can be released. If a truck is due to head south, mention the departure time so urgent work can be prioritised where possible.
