Electrical System
General
Overview
The 239DFS is equipped with a standard 12V DC Electrical system.
The 239DFS can only be rigged for a single motor. If the boat is rigged without an optional battery selector switch, the boat will be rigged for x1 Group
27 battery. If the battery selector switch is installed, the boat will be rigged for x2 Group 27 batteries. Key West recommends this option for those who
wish to install an optional windlass to their boat due to the high power demand. The battery(s) will provide power to the engine, house and optional
windlass system.

12V power is distributed to the 12V factory installed systems through individual circuit breakers located beneath their respective switches on the main
switch panel. All 12V systems are grounded individually to a grounding block located inside the console. The grounding block is than grounded directly
to a battery. A 30amp main circuit breaker is installed adjacent to the batteries to protect the house systems from overload and is connected either
directly to the batteries or the optional battery selector switch. Additional circuit breakers for the auto bilge pump and stereo memory are wired
directly to either the battery or battery selector switch. If a windlass is installed, an additional 50amp circuit breaker will be installed. The system is
designed so that turning the battery switch/switches off will still allow the bilge pump to function in an automatic mode. Key West recommends that
boats that are going to be left in the water or in a boat lift, where access to the drain plug is not feasible, be installed with a battery charger to prevent
discharge by the bilge pump. Trim Tabs and optional power steering are connected directly to the battery and feature overcurrent protection. They do
not energize until the engine ignition switch is turned to the “On” position.

Maintenance
All connections in the electrical harness feature deutsche connectors and heat shrink butt connectors to minimize corrosion. Key West recommends
that all connections and terminals be checked at least twice a year and sprayed with a corrosion inhibiting spray at least once a year to protect and
maintain the integrity of electrical connections. For troubleshooting purposes and further information, a schematic of the electrical harness is available
for download in PDF on the 239DFS main page.
