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.

#539 Common question asks
Can a bad shore power cord damage onboard equipment?
-
Yes. A damaged or undersized shore power cord can cause voltage drops, overheating, and unstable power delivery. This can damage sensitive electronics, battery chargers, inverters, air conditioning units, and other onboard systems.
-
-
#537 Common question asks
When should a shore power cord be replaced?
-
A shore power cord should be replaced if it shows signs of overheating, melted pins, cracked insulation, corrosion, discoloration, or intermittent power loss. In high-use marina environments, cords often need replacement every few years to maintain safety and reliability.
-
-
#535 Common question asks
What do you check during a shore power system inspection?
-
We inspect the shore power cord, plugs, inlet, breakers, wiring connections, grounding, polarity, and load balance. We also check for heat damage, corrosion, loose connections, and compliance with ABYC safety standards.
-
-
#533 Common question asks
Why is a shore power system inspection important?
-
A shore power inspection checks that your boat receives power from the marina without overheating, voltage drop or electrical leakage. Faulty shore power connections are a common cause of fires and equipment damage at the dock, and salt air speeds up the corrosion behind them.

#531 Common question asks
Do you offer warranty and post-installation support?
-
Yes. Our workmanship is warranted for 90 days from the invoice date, and panels, charge controllers and batteries carry their manufacturers' own warranties, which vary by product. You get the product documents and a wiring diagram, and you can call us with questions after the install.
-
-
#529 Common question asks
How long does a marine solar installation usually take?
-
It depends on the size of the system and how the panels are mounted; custom mounts, battery upgrades or an inverter add time. The written estimate you get before we start shows the expected hours.
-
-
#527 Common question asks
Is the installation safe for saltwater and harsh marine conditions?
-
Yes. We use marine-rated, corrosion-resistant components made for salt air, and we follow ABYC practice for wiring, fusing and cable support to protect the installation from moisture, vibration and corrosion.
-
-
#525 Common question asks
What components are included in a marine solar installation?
-
A complete system typically includes marine-grade solar panels, MPPT charge controllers, proper wiring and fusing, battery integration, and system monitoring. We also ensure correct bonding and grounding to meet marine safety and corrosion-prevention standards.
-
-
#523 Common question asks
Can solar panels power air conditioning or large onboard appliances?
-
Not on their own. Solar suits lighting, electronics and refrigeration, but air conditioning and other high-draw appliances need far more power than the panels on most boats can make, so they run on shore power or a generator. Solar and a larger battery bank can help between generator runs, and we size the system from your actual loads.
-
-
#521 Common question asks
Do you design custom solar systems or only install pre-made kits?
-
We design fully custom marine solar systems based on your boat type, available space, power consumption, and cruising habits. Every installation is tailored to maximize efficiency while maintaining safety, aesthetics, and proper marine electrical standards.
