Common electrical problems on Charleston boats
Corrosion on battery terminals, connectors and grounds is the usual culprit in salt water. Other common issues are batteries at the end of their life, a failing charging system, chafed or undersized wiring, blown fuses or breakers, and problems after aftermarket electronics were added.
Boat wiring has its own standards. Marine wire, sealed connectors and proper fusing matter, and many technicians follow ABYC (American Boat and Yacht Council) practices. Ask about it if you're having electronics installed.
Electronics installs
Chartplotters, fish finders, radios, trolling motors and battery chargers all need correct wiring and fusing. A technician can install them cleanly and make sure the system can handle the added load.

Common questions
Why does my boat battery keep dying?
Common causes are an old battery, a parasitic draw from something left on or miswired, corroded connections, or a charging problem. A technician can test the battery, charging output and draw to find which one.
Can electrical work be done at my dock?
Most of it, yes. Mobile technicians routinely troubleshoot wiring and install electronics at the dock or on a trailer.
