COMPRESSOR INSTALLATION: Fig. 2 & 3
4. 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.
5. 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 mounting bracket’s slot on the side of the compressor.
Secure the compressor using the lock washer/nut provided as shown in
Fig. 2.
6. Using the plastic tubing provided, cut to size
and connect the compressor to the horn’s inlet 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,
always keep the plastic tubing as short as
possible.
WIRING:
ELECTRICAL CONNECTIONS FOR USING A NEW HORN BUTTON SWITCH Fig. 4
7. Install the horn relay provided, located close to the compressor, in a dry interior location with the terminals
facing downward.
8. Connect relay terminal 87 to the compressor’s positive (+) terminal. Use 16-gauge wire or heavier.
9. Connect relay terminal 85 to the horn button switch terminal. (Horn switch not provided).
10. 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.
11. Connect relay terminal 30 & 86 to
positive (+) 12-volts such as battery,
alternator, fuse block or etc. Use
16-gauge wire or heavier.
IMPORTANT:
Protect the electrical circuit with the
twenty (20)-amp inline fuse provided.
WARNING: The inline fuse must be
connected directly to the power source.
12. Connect the compressor’s negative
(-) terminal to boat’s negative (-) battery
post or any clean metal negative surface. Use not less than 16-gauge wire.
