Sure Shot Marine

Electrical & Systems Diagnostics

Services

Focused diagnostics for marine electrical and onboard systems.

The work is structured: define the symptom, capture measurements, isolate the cause, and document results with practical next steps.

Core services

Electrical system diagnostics fault isolation

Intermittent issues, parasitic draw, unexpected voltage behavior, unexplained shutdowns, breaker trips.

Battery & charging evaluation performance

Alternators, shore chargers, DC-DC chargers, regulators, battery banks, wiring and protection checks.

NMEA 2000 troubleshooting network

Backbone power, termination, drop integrity, device communication, voltage drop and noise checks.

Power quality checks under load

Voltage stability, grounding concerns, system behavior under realistic operating loads.

Bilge & safety systems verification

Pumps, float switches, alarms, and associated power supply integrity checks.

Pre-purchase electrical inspection independent

Condition assessment of onboard electrical systems with documented findings for decision support.

Testing & Verification

Diagnostic work is guided by measured data and structured evaluation. Testing methods are selected based on the system and symptom — not applied indiscriminately.

  • Insulation resistance testing (where appropriate)
  • Load-based voltage and charging performance analysis
  • Thermal imaging of conductors and terminations
  • Grounding and bonding verification
  • Power quality evaluation under operating conditions

Findings are documented clearly so corrective actions are based on verified system behavior, not assumption.

Typical deliverables

  • Summary of symptoms and operating conditions
  • Measurements and key observations (voltage, current, network checks, etc.)
  • Root cause findings or narrowed failure modes
  • Recommended corrective actions and priority
