Your Go-To Mobile Auto Electrician in Gillieston Heights for Heavy Vehicles

When your truck, machinery, or diesel vehicle stops working, you need more than a quick fix — you need a reliable specialist who understands heavy vehicle systems inside out. East Coast Diesel & Auto Electrical combines deep industry experience with advanced diagnostic technology to deliver fast, effective, and trustworthy repairs across Gillieston Heights and the wider Maitland region.

1. Locally Based, Rapid Mobile Response: We’re locally based near Gillieston Heights, meaning faster call-outs and shorter downtime for your vehicle or fleet. Whether you’re on the job site, on the road, or working in a paddock, we arrive equipped with the right tools to get your vehicle back up and running quickly — without the need for towing.
   
   
2. Heavy-Vehicle Electrical Experts: Our team specialises in heavy trucks, diesel engines, and earthmoving equipment. From full wiring replacements and ECU fault diagnostics to alternator, starter motor, and lighting repairs, we handle complex electrical systems that most general auto electricians avoid. Every repair is completed to OEM standards using quality components designed for commercial durability.
   
   
3. Advanced Diagnostic Capability: Using dealer-level scan tools, we perform on-site fault scanning for all major heavy vehicle makes and models — including ECU, ABS, SRS, and transmission systems. This allows us to pinpoint faults accurately and prevent costly trial-and-error repairs. Our advanced systems ensure your truck or machinery returns to full operation faster, saving you time and lost productivity.
   
   
4. Full Air Conditioning & Electrical Service: Unlike many mobile electricians, we also provide complete heavy-vehicle air conditioning repairs, including regassing, leak detection, and electrical fault testing. Whether your A/C has stopped blowing cold air or your cabin controls have failed, we diagnose and fix the issue on-site, keeping your operators comfortable and safe.
