Behind the Scenes... Every retrofit, installation and fitout we do is designed to look like it belongs there — clean, functional, and seamless.

With our in-house CNC plasma cutter, router and laser, we can cut accurate, sleek looking gauge panels, brackets and, switch plates.

A recent upgrade with an Enerdrive battery monitor installed in a Stoney Creek camper trailer which meant a new gauge panel.

Crank, No Start? Wiring Might Be the Culprit ⚡

A vehicle that cranks but won’t start can be caused by more than just poor batteries, or mechanical faults.

Often, the issue is damaged or broken wiring — and that can cause all sorts of headaches across modern vehicles and machinery.

We utilise some very fancy equipment and a bit of brain power to solve these issues;
🔍 OEM-level wiring diagrams & diagnostic info - Isuzu, Toyota, Cummins, Caterpillar, and more.
🧰 Specialised testing and harness tracing tools.
⚡ A bit of experience and a love of solving puzzles.

This means we can quickly locate, diagnose, and repair wiring faults to get you back up and running — fast and reliably.

Whether it’s a 4WD, truck, or machine, we’ll find the issue before it costs you more downtime.

We were caffeinated and on the road bright and early this morning – keeping wheels turning and diesel burning! 🚜💨

A fresh set of Bosch batteries went into this loader nice and early so the operators could get straight into a full day’s work. 💪 Bosch batteries: tough, reliable, and built to perform – time after time.

🔧 For any field service or breakdown enquiries, give us a call on 0417 296 459 – Pinnacle Diesel will get you moving again.

A brand-new TOYOTA Prado 250 Series rolled into the workshop this week and drove out better equipped!

We fitted a GME XRS-370 UHF radio, paired with a TLR Products aerial mounting bracket for a clean, functional install. To finish it off, we fabricated a handpiece bracket – keeping it secure and accessible without drilling into interior trim.

Whether it’s UHF installations, repairs, troubleshooting, or air-conditioning, Pinnacle has you covered.

Drop into our Bullsbrook workshop or give us a call today!
