Control systems
CAN bus and multiplex diagnosis, ECU and control module fault codes, sensor and actuator testing, calibration checks.
Heavy machinery electrical diagnosis & repairs
Mobile auto electrical fault finding and repairs for excavators, dozers, loaders, trucks, tractors and plant across Ipswich and South East Queensland — done with scan tools and test equipment instead of guesswork, so you replace the component that actually failed.
The problem
Intermittent faults cost more than the part
A machine that drops out once a shift will burn more money in lost production than any component on it. Modern plant runs multiplexed control systems where a chafed wire in the loom can throw codes three modules away from the actual fault.
We trace it properly: codes, live data, load testing and voltage drop — then we show you what we found before we quote the fix.
- Manufacturer-level scanning across mixed-brand fleets
- Oscilloscope and voltage-drop testing on live circuits
- Repeat-fault analysis so it doesn't come back next month
- Written report for your maintenance records
What we cover
Every circuit on the machine
Charging & starting
Alternators, starters, batteries, isolators and battery management. Parasitic drain testing and no-start diagnosis.
Looms & harnesses
Chafe, corrosion and vibration damage. Connector and terminal replacement, section repairs and full rewires.
Safety circuits
Isolators, emergency stops, interlocks, reverse alarms and beacon circuits tested and rectified.
Lighting & signals
Work lights, road lighting, trailer plugs and marker circuits — including chasing the faults that only show up in the wet.

Common questions
Before you call
Yes — nearly every job is done on site. We carry diagnostic equipment, test gear and common componentry in the service vehicle so most faults are found and fixed in the one visit.
We work across mixed fleets — earthmoving, agricultural and heavy road transport. If we can't communicate with a module we'll tell you up front rather than burning your time on it.
Always. You get the diagnosis in plain language plus a written quote before repair work starts, and a report at completion you can file against the machine.
Ipswich, Brisbane and the surrounding South East Queensland region. Further afield, give us a call and we'll tell you honestly whether we're the right fit.
