2. Remove the trumpet from the horn body by unscrewing it.
3. Mount the bracket to the scoreboard frame using #10 hardware provided, and

connect the horn harness to the horn wires. Refer to Drawings A-44197 and A-88563.

Note: When replacing a horn:
1) Use

" bolts, nuts, and lock washers provided to attach the horn body to the

mounting bracket so that the horn is on the same side as the short flange (the
horn should be pointing downward).

2) Be sure to mount the horn to the bracket so that the wires are facing the bottom

of the cabinet to prevent water from running along them.

3) Attach the copper ground lug to the bottom-right corner of the mounting bracket

using the bolt and serrated washer and nut provided, and connect the green wire
from the horn to the ground lug.

4. Connect horn relay harness with white plug to power entry panel marked HORN or

to the right side of driver enclosure to jack marked J-101.

Note: A 2-pin to 4-pin adapter harness may be needed to connect new horn assembly
to scoreboards built prior to April 2006.

5. Close the access panel and screw the trumpet back onto the horn body.
6. To test the horn, power on the scoreboard and control console, and press HORN.
