Electrical Diagnostics

Trace the fault to the source.

Electrical faults in modern European vehicles can manifest as mechanical symptoms, safety warnings, or complete system failures. Without the right tools and knowledge, they're nearly impossible to trace accurately.

Troy uses a digital oscilloscope to visualize electrical signals, factory wiring diagrams to trace circuits, and proprietary software to communicate with every module on the vehicle network.

Frequently Asked Questions

How do you find intermittent faults?

We use live data logging and freeze frame history to capture faults that don't appear during a static scan.

Can you find a parasitic battery drain?

Yes. We perform systematic parasitic drain testing to identify which circuit or module is causing battery discharge.

Do you use oscilloscopes?

Yes. A digital oscilloscope is essential for signal-level electrical diagnosis — we use it regularly.
