What are the common signs of electrical problems on a boat?

Common symptoms include: power failure, flickering lights, non-working onboard electronics, burning smell from wiring, engine start issues, or batteries draining too fast. If you notice any of these, schedule a marine electrical diagnostic immediately.

What is the process for marine electrical repair?

The process starts with a complete 12V/24V system diagnosis. We locate shorts, surges, or wire damage. Then we repair or replace faulty parts like fuses, relays, batteries, alternators, or entire harnesses. Final step: full system testing to ensure safety and functionality.

Do you offer upgrades for boat electrical systems?

Yes, we specialize in system upgrades. We replace outdated wiring, install modern switch panels, smart chargers, inverters, solar systems, and remote-control modules for energy efficiency and improved reliability.

Which boat electrical systems do you repair?

We service and repair: Navigation and deck lighting Bilge and freshwater pump wiring Control panels and engine start systems Alternators, starters, and charging systems Shore power and AC/DC conversion VHF, GPS, radar, and marine electronics wiring

How much does marine electrical repair cost?

Prices vary depending on the issue and vessel size. Diagnostics start at $250. Minor repairs usually range between $300–$700. Full system rewiring or upgrades start at $1,000+. We provide free estimates after inspection.

Do you offer a warranty on electrical repairs?

Yes, all electrical repairs come with a 3 to 12-month warranty, depending on the service and parts used. We also provide full post-repair documentation for your records.

Do you offer mobile marine electrical repair?

Yes – we provide mobile boat electrical services in Long Beach, Wilmington, San Pedro, and surrounding marinas. Our fully equipped service vehicle comes to your dock or slip.

Exorcising Gremlins

Safe Wiring.
Safe Boating.

Bad wiring is the #1 cause of boat fires. From flickering navigation lights to bilge pumps that won't kick on, we diagnose and repair the electrical faults that keep you stuck at the dock.

The Gremlin Hunt

Electrical issues on boats are often hidden. We use voltage drop testing and continuity checks to trace wires through impossible places, finding the one corroded ground or chafed wire causing your headache.

ABYC Standards

We don't use wire nuts or electrical tape. Every repair meets ABYC standards: Marine-grade tinned copper wire, proper color coding, adhesive-lined heat shrink terminals, and circuit protection.

Corrosion Control

Saltwater wicks up wire insulation, turning copper into green dust (black wire disease). We cut back to clean metal or re-run entire circuits to ensure low resistance and reliable operation.

The Repair Process.

Methodical troubleshooting.

Symptom Check

We replicate the failure. Does the breaker trip immediately? Does the light dim when the pump turns on? This guides our search.

Trace & Test

Using multimeters, we check for voltage at the source, the switch, and the load. We identify if the break is on the positive side or the negative ground.

Marine Repair

We replace the faulty component using crimped, heat-shrunk connections. We secure cabling with cushion clamps to prevent future vibration damage.

Load Verification

We run the repaired system under full load for 15 minutes to ensure fuses hold and wires do not get hot to the touch.

Common Questions

Why does my breaker keep tripping?

A tripping breaker is doing its job. It means there is a "short to ground" or the device is drawing too much power (like a seized pump motor). DO NOT hold the breaker closed; you will start a fire.

Can I use wire nuts on my boat?

Absolutely not. Wire nuts vibrate loose and allow corrosion. We only use marine-grade crimp connectors with adhesive heat shrink to seal out moisture.
