Routine Inspection = Major Failure Prevented 🚜

During a scheduled inspection today, I found a missing mounting bolt in a fire suppression harness.

👉 The harness had started rubbing through wiring.
👉 This could have caused machine downtime.
👉 Worse — the fire suppression system may have disabled itself when needed most.

This fault now requires:
✔ Harness repair
✔ Mounting repair
✔ Correct securing to manufacturer spec

Most people don’t realise — a proper heavy machinery inspection takes around 4 hours and follows strict manufacturer checklists designed to prevent failures before they happen.

If you run equipment, prevention always costs less than downtime.

📩 DM “🚜” and I’ll send you my fleet inspection pricing + service form.

🔥 SPOT THE PROBLEM? 🔥

That discolouration isn't normal. A fuse running hot = a serious electrical fault waiting to happen.

We found this scorched fuse on a recent job—and it's a prime example of why your electrical system needs professional eyes.

⚠️ WHY THIS MATTERS:
🔌 Overheating fuses signal underlying circuit issues
🔥 Risk of fire damage to your entire electrical system
💰 Catching it early saves you thousands in repairs
⏱️ Could be the difference between a quick fix and total breakdown

A faulty fuse isn't just an inconvenience—it's a safety hazard that affects your whole vehicle's performance and your safety on the road.

🔍 HOW WE FIX IT:
✓ Full electrical system inspection & diagnosis
✓ Identify root cause (not just swap the fuse)
✓ Preventative maintenance to stop it happening again
✓ Professional repair to safety standards

This is why routine electrical maintenance matters. Small issues caught early = major issues prevented.

Don't ignore the warning signs.

👉 DM us to get your electrical system checked before it becomes a major problem. We'll diagnose it fast and get you back on the road.
