Accurate electrical diagnostics for vehicles and touring setups
Electrical problems rarely appear in a straightforward way. A vehicle that struggles to start, accessories that stop working, or warning lights that appear intermittently may all be connected to the same fault.
Amp Up Auto Electrical provides professional auto electrical diagnostics and fault-finding to locate those problems quickly and accurately. Instead of replacing parts unnecessarily, the focus is on systematic testing and careful electrical fault diagnosis to pinpoint the source of the issue so the correct repair can be carried out the first time.
From stubborn battery drains to hard-to-trace vehicle wiring faults, our fault finding gets to the real cause rather than treating the symptoms.
Computerised Battery & Starting Tests
We go beyond a simple voltmeter. Using Computerised Battery Testing, we check for charge capacity, voltage stability, and cold-cranking amps (CCA) to ensure your vehicle starts reliably every time, regardless of the conditions.
Alternator & Charging System Analysis
A healthy battery is useless without a strong charging system. We perform comprehensive Charging System Checks and Voltage Drop Analysis to confirm your alternator is supplying consistent power and maintaining your batteries while the vehicle runs.
Electronic Diagnostics & Fault Scanning
Modern vehicles require modern tools. Our Electronic System Diagnostics include professional Fault Code Scanning to identify issues within onboard computers, sensors, and vehicle electronics before they become major breakdowns.
Electrical Wiring & Earthing Repairs
Corrosion and vibrations are the enemies of off-roaders. We conduct thorough Electrical Wiring Inspections, specialising in Short Circuit and Earthing Repairs to fix flickering lights, power loss, or intermittent electrical “gremlins.”
Solar & Off-Grid Performance Audits
Ensure you aren’t leaving power on the table. We perform Solar Performance Audits on existing setups to test panel output, regulator efficiency, and accessory draw, ensuring your fridge and lights stay powered for the duration of your trip.
Troubleshooting & Repair Planning
Once our testing identifies the source of the issue—whether it’s an aftermarket accessory or a factory loom—we explain the fix clearly. We provide a structured Repair Plan so you can head back off-road with total confidence in your 12V system.
Auto Electrical Diagnostics and fault-finding service pricing
The cost of auto electrical diagnostic and fault-finding varies depending on the vehicle and the nature of the electrical issue.
Factors that may influence the price include:

- The time required for fault finding and locating the problem
- The type of vehicle and electrical system involved
- Whether the issue involves vehicle wiring faults or the charging system
