Electrical System
Optional T-Top (189FS and 203FS)
If your boat is fitted with an optional canvas T-Top, it will be rigged with spreader lights and additional
courtesy lights. These lights are controlled by switches located on the port side of the electronics box. A fuse
block with ATC fuses is installed inside the electronics box to provide overcurrent protection. Power is
supplied to T-Top accessories via a single red wire that is connected to the 30amp house breaker inside the
console. It connects to the fuse block where power is than distributed to the T-Top accessories through their
respective fuses. All T-Top/Hardtop accessories are grounded to a grounding post on the fuse block which is
connected to the ground post on the main fuse block inside the console.
Battery Charger (189FS and 203FS)
As an option, a battery charger can be installed that will charge one or both batteries, depending on the
battery installation. The battery charger converts AC power into DC power that is used to charge the
batteries. The charger is powered by a plug on the console that receives a standard 110V plug from the
female end of a 110V extension chord. It allows you to plug the boat into a regular 110V outlet. Please
consult the battery charger’s manual before using your charger for the first time. If the optional Battery
selector switch is installed, it does not need to be on to direct the charge from the battery charger.
Electrical System 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.
