Marine Electrical Diagnostics
Focused troubleshooting for intermittent faults, battery drain, voltage drop and unexplained loss of power aboard yachts and boats.
Find the cause. Define the next step.
What you may be noticing
- A fault that disappears before it can be traced
- Batteries losing charge when equipment is off
- Breakers tripping under a particular load
- Equipment restarting or losing power unexpectedly

The diagnostic approach
Start with the conditions around the fault: what was running, which power source was connected, and when the problem appeared. Circuit testing and voltage measurements help narrow the investigation from a symptom to a specific circuit or component.
What to expect
Describe the symptom and share any previous repair history. The scope of diagnostic work depends on access, system complexity and whether the fault can be reproduced. Findings inform the proposed repair or next stage of investigation.
