Our mobile auto electricians provide full wiring repairs, alternator and starter motor replacements, light upgrades, and control system installations for trucks, plant machinery, and utes over 3 tonnes.

Whether you’re managing a transport fleet or running a single workhorse vehicle, we deliver on-site diagnostics and lasting electrical repairs that get your equipment back on the road faster.

We handle all aspects of heavy vehicle air conditioning — from regassing and compressor replacement to climate control troubleshooting and electrical diagnostics.

Our team uses high-quality refrigerants and leak detection tools designed for heavy-duty equipment and transport trucks operating in hot, dusty conditions.

From excavators to loaders and graders, we repair and maintain plant and machinery A/C systems on-site.

We carry the fittings, hoses, and sensors needed to service construction and agricultural equipment without you having to move it off-site — saving valuable downtime for operators and site managers.

We also provide complete A/C regas and electrical diagnostics for light vehicles, utes, and service cars used in your business fleet.

If your air conditioning is blowing warm air or has an electrical fault, our mobile service will diagnose the issue and repair it at your home, depot, or job site.

Our diesel technicians are qualified in heavy commercial vehicle mechanical technology, offering fuel system testing, injector wiring repairs, and ECU fault scanning for diesel engines.

Whether it’s a hard-start issue, loss of power, or fault codes showing on the dash, we identify and repair the root cause quickly and accurately.

Using dealer-level diagnostic tools, we perform on-site fault scanning for engine, transmission, ABS, and airbag systems.

Our ECU reprogramming and reset capabilities ensure accurate repairs and minimal downtime — especially important for commercial fleets and civil machinery.

When your truck or heavy vehicle stops unexpectedly, our emergency roadside team is ready to respond.

We provide 24/7 mobile breakdown assistance, electrical fault repair, and starter or alternator replacement on the spot. Our aim is to get you moving again safely, without the need for towing or long workshop delays.

Our Story

Founded by local tradesman Dillon James, East Coast Diesel & Auto Electrical was built on one core value — doing the job right, no shortcuts. With over 15 years of hands-on experience in diesel mechanics and auto electrical work, Dillon has worked across transport, civil construction, and agricultural industries throughout the Hunter region.

After years sub-contracting for major fleets, he saw the need for an honest, mobile service that puts reliability ahead of profit. East Coast Diesel was born from that principle — a business that shows up, fixes what others can’t, and gives straight answers without jargon. Every repair is handled by a qualified heavy-vehicle electrician with a genuine commitment to keeping your trucks, utes, and machinery safe, compliant, and dependable.
