Electrical Troubleshooting & Fault Finding
The calls nobody else wants: the breaker that trips at 2 a.m., the circuit that works until it's hot, the fault three technicians couldn't find. We work high and low voltage from the print with real instruments until the cause is identified.

What's included
Prism Marine Electric provides electrical troubleshooting & fault finding for yachts, superyachts and sportfish vessels in Fort Lauderdale and throughout Broward, Palm Beach and Miami-Dade County — dockside, at anchor or during a yard period. Licensed, insured and available 24/7, with worldwide travel for vessels under our care.
- Intermittent fault and ground fault tracing
- Insulation resistance and continuity testing
- Thermal imaging of panels, breakers and terminations
- Voltage drop and load analysis under real conditions
- Circuit tracing and as-built drawing correction
- General maintenance and preventative inspections
- Repairs from another surveyor's deficiency list
Our method
Anything a wire touches on board is in our lane — high voltage and low voltage, AC and DC. We diagnose by measurement, not by replacing parts until the symptom moves.
General maintenance is the other half of this: scheduled inspections, thermal scans and torque checks that find the failure before it strands the vessel or shows up on a survey.
Signs it's time to call
- A recurring fault nobody has been able to find
- Breakers tripping with no obvious cause
- Systems that fail only when hot, wet or underway
- A punch list of electrical items needing repair
