Boat Systems Section 4
Signal Horn
Your boat is equipped with a 12 VDC signal horn. The
signal horn is installed on the control console face.
The HORN push button switch is located on the con-
sole face, near the steering wheel. This signal horn
satisfies United States Coast Guard Navigation Rule
36 for signals to attract attention.
The signal horn circuit is protected by a 10-amp blade
fuse located in the accessory fuse block inside the
console.
Turning the house battery OFF-ON switch to the OFF
position at the end of your mission will cut power to the
signal horn circuit.
Battery Status Indicator
Your boat is equipped with a battery status indicator
panel. The panel is mounted at the helm station. The
panel has a green LED that is lighted anytime a bat-
tery switch or a boat accessory circuit is powered and
active.
Turn all battery OFF-ON switches to the OFF posi-
tion before you leave the boat unattended for any
period of time. Check to make sure that the bat-
tery status green LED is not lighted.
Leaving the boat unattended with the battery status
green LED lighted might allow one or more of the bat-
teries to become discharged.
Bilge Pump Special
The only exception to the 12 VDC circuit control
described above is the bilge pump system. The bilge
pump system has an uninterruptible power supply that
originates at the battery side of the engine battery
OFF-ON switch. The bilge pump system is powered
and active regardless of the position selected on either
of the battery OFF-ON switches.
