Battery System Service and Replacement
A weak or failing battery is the most common cause of no-start situations on the water. We test battery banks, charging circuits, and isolators to confirm whether a battery needs reconditioning or full replacement. Ignoring a marginal battery before boating season almost always leads to a call from the ramp. – Load testing and capacity checks – Dual-bank and lithium battery installations – Battery isolator and combiner wiring

Common Signs You Need Service
Catching an electrical problem early on a boat is far less expensive than dealing with a fire, a flooded bilge, or a complete system failure in the middle of the Cape Fear River — prompt attention to warning signs keeps repair costs manageable and keeps your crew safe.
Flickering or Dead Lights:
Navigation or cabin lights that flicker or go out entirely suggest a corroded connection, a failing switch, or an undersized circuit. Left unaddressed, the root cause can spread to other circuits.
Repeated Breaker Trips:
A breaker that keeps tripping is protecting you from an overload or a short — it is not a problem solved by resetting it. Persistent trips indicate a wiring fault or a failing component that needs professional diagnosis.
Corrosion on Terminals:
Green or white buildup on battery terminals, bus bars, or wire ends signals active moisture intrusion. Corroded connections increase resistance, generate heat, and can ignite surrounding insulation.
Electronics Losing Power Underway:
Chartplotters, VHF radios, or depth sounders that reset or go blank while running point to a loose connection or a voltage drop in the supply circuit — both are safety concerns that our marine diagnostic services can pinpoint quickly.
Frequently Asked Questions
How much does a marine electrical diagnosis typically cost?
Diagnostic pricing depends on the complexity of the fault and how long it takes to trace. Simple issues like a blown fuse or a corroded terminal are often identified in under an hour, while intermittent faults in a multi-circuit system take longer. We always provide a clear quote before any repair work begins so there are no surprises.
Can you work on my boat at the marina without hauling it out?
Yes — on-site electrical service at your marina, dock, or dry-stack facility is exactly what we do. Our service vehicles carry diagnostic tools and common parts, so most repairs are completed in a single visit without your vessel ever leaving the water.
How often should marine wiring be inspected?
For boats used in saltwater, an annual wiring inspection is a sound practice. Saltwater accelerates corrosion inside terminals and connectors faster than most owners expect, and catching a deteriorating connection before it causes a failure is always cheaper than an emergency repair. Spring commissioning is a natural time to schedule a check.
Do you install new marine electronics as well as repair existing systems?
Absolutely. We install chartplotters, VHF radios, AIS transponders, depth sounders, and other electronics, including proper grounding and NMEA network integration. If you're upgrading your helm station before the season, reach out alongside your marine diagnostic services appointment to bundle the work efficiently.
What brands of marine electrical components do you work with?
We work with all major marine electrical brands — Garmin, Raymarine, Humminbird, Blue Sea Systems, Victron, and others. Our focus is on using marine-rated components that meet ABYC standards, regardless of the brand on the label.
