COMPRESSOR INSTALLATION: Fig. 2 & 3
5. Install the compressor in a dry interior location.
IMPORTANT: The compressor should not be mounted further than 30 inches
from the trumpet to ensure best sound.
6. To secure the compressor, drill one
3/16” hole. When possible, mount the
compressor vertically (air outlet on top).
Install the head of the bolt into the slot
on the side of the compressor. Secure
the compressor using the lock washer/
nut provided as shown in Fig. 2.
7. Using the plastic tubing provided, cut
to size and connect the compressor to
the horn’s two air inlets using the “Y”
connector provided as shown in Fig. 3.
WARNING: Avoid making any kinks
or sharp bends in plastic tubing that
can reduce air flow and alter the horn’s
sound. For best performance and sound
always keep the plastic tubing as short
as possible
WIRING:
ELECTRICAL CONNECTIONS FOR USING A NEW HORN BUTTON SWITCH Fig. 4
8. Install the horn relay provided, locate close to the compressor in a dry interior location with the terminals
facing downward.
9. Connect relay terminal 87 to the compressor’s positive (+) terminal. Use 16-gauge wire or heavier.
10. Connect relay terminal 85 to the horn button switch terminal. (Horn switch not provided).
11. The horn switch’s other terminal
is connected to negative (-) such as
the (-) battery post or any clean metal
negative surface. Use 18 gauge wire or
heavier.
12. Connect relay terminal 30 &
86 to positive (+) 24-volts such as
battery, alternator, fuse block or
etc., using 16-gauge wire or heavier.
IMPORTANT: Protect the electrical
circuit with the fifteen (15)-amp inline
fuse provided.
WARNING: The inline
fuse must be connected directly to the
power source.
13. Connect the compressor’s negative
(-) terminal to boat’s battery, (-) post or
any clean metal negative surface. Use not less than 16-gauge wire.
RECAP OF RELAY TERMINAL CONNECTIONS:
