Marine Electrical Repair in Long Beach and San Pedro
We diagnose and repair boat electrical systems at your slip, dock or storage yard from Marina del Rey to Newport Beach, or at our San Pedro shop. We trace the fault from the batteries to the panel, find the cause and quote the repair before any work is done.
What the work covers
The core service is marine electrical repair and troubleshooting: dead circuits, tripping breakers, corroded connections and wiring that has been added to over the years. The work also covers:
- Batteries and charging: marine battery replacement and charging system repair, plus lithium LiFePO4 battery conversions and power upgrades.
- Shore power: shore power inspection and cord replacement.
- Corrosion: electrolysis and galvanic corrosion testing, with a check of the bonding system.
- Solar: marine solar panel design and installation.
- Networks: NMEA 2000 networking and digital switching systems.
- Lighting, sound and internet: underwater LED lighting, marine audio upgrades, Starlink installation, and marine electronics installation and repair.
Parts are quoted with the job.
When to call
- Batteries that go flat overnight or will not hold a charge
- A breaker that keeps tripping, or a circuit that works one day and not the next
- A shore power plug or inlet that looks burnt or feels hot
- Zincs that wear away fast, or pitting on props and running gear
- Electronics that reset, flicker or drop off the network
Questions about marine electrical repair
Why do boat electrical problems come and go?
Salt air and moisture corrode terminals and crimped joints. A weak connection can pass a quick check and still fail when the circuit carries current, so we test circuits under load.
Is a lithium battery conversion a simple swap?
Usually not. Lithium batteries charge differently from lead-acid, so the charger, alternator and battery monitor often need changes as part of the job.
Book a visit: submit a ticket with the boat, where it is kept and which circuits are acting up, or call (562) 542-7296.

#3 Common question asks
What is the process for marine electrical repair?
-

We start by diagnosing the 12V or 24V system to find shorts, voltage drops or damaged wiring. You then get a written estimate for labor, parts and the trip fee, and we repair or replace the faulty parts (fuses, relays, batteries, alternators or harnesses) only after you OK it. We finish by testing the whole system.

#1 Common question asks
What are the common signs of electrical problems on a boat?
-

Common signs are power failures, flickering lights, electronics that stop working, hard engine starts and batteries that run down too fast; if you notice any of them, book a diagnostic. If you smell burning wiring, turn off the battery switches and the shore power breaker right away, and do not use the system until it has been checked.
