2. INSTALLATION
2.1 General Information
Shipping papers accompany each scoreboard. Check carefully to see that you receive the following:
1 ea Football Display (2 Crates)
1 ea Control Console
1 ea Service Manual
1 ea Mounting Hardware Package
1 ea AC Adaptor
1 ea Horn (if ordered)
IMPORTANT!
The MP-40 cable supplied by ALL AMERICAN SCOREBOARDS for use on the Microprocessor
based scoreboards is specically designed for this system. Use of a substitute cable may void the
warranty on the scoreboard!
2.2 Installation
Select the location best suited for visibility by the majority of spectators. Preferred position is facing east
or north to avoid direct sunlight on the face of the scoreboard, if day games are played. For permanent
mounting to uprights, see the enclosed installation drawing in Section 6. The MP-40 data cable carries
only low voltage signals and therefore can be installed with or without conduit. Consult Section 6 for
junction box and scoreboard wiring.

2.3 Electrical connections
The MP-3432R scoreboard requires two 120 V. 40 AMP AC circuits. This can be accomplished by
a single phase 3 wire 60 amp service.
IMPORTANT!!!
To protect the control from damage, it is advisable that you disconnect the control and
store in a dry secure area when not in use.

4. MAINTENANCE AND TROUBLESHOOTING
4.1 Introduction
This section gives maintenance and troubleshooting information. Included are troubleshooting guides for
typical scoreboard malfunctions. If the cause of a problem cannot be determined, please contact the
Customer Service Department.
WARNING!!
110 VAC wires are exposed whenever the cover over the controller assembly is
removed from the scoreboard. Use extreme caution during troubleshooting or repair.
To avoid possible damage to equipment or personal injury, always turn off the main
power before removing the cover or replacing assemblies, or replacing lamps.
4.2 Test Equipment
A simple analog or digital voltmeter will be sufcient for all user repairable problems. Printed circuit
boards requiring troubleshooting should be returned to the factory.
4.3 Troubleshooting
Whenever possible, follow the troubleshooting guides prior to contacting the customer service
department. If a problem not described in the guides exists, contact the customer service
department immediately. Refer to the diagrams provided for assistance in troubleshooting scoreboard
malfunctions.
4.4 Troubleshooting Guides
(A) Scoreboard doesn’t light and console doesn’t work:
(a) Check that the main power switch is turned on.
(b) Replace any defective or blown fuses.
(c) Check the power connections and voltages at the scoreboard.
(d) Contact the Customer Service Department.
(B) Scoreboard digits don’t light but the console works:
(a) With the main power switch “OFF”; remove the cover over the controller assembly.
(b) Check all connections.
(c) Turn the main power “ON”.
(d) If the scoreboard still doesn’t light, check the transformer voltage going to the
receiver PCB (printed circuit board) assembly (blue wires) using a voltmeter set
on the 12 VAC or higher scale.
If the voltage is less than 8 VAC contact the Customer Service Department.

9
s:\shared\stacey\scoreboard manuals\incomplete manuals\mp-3432r.indd
401 South Main Street • Pardeeville, WI 53954 • 800-356-8146 08/01/02
If the voltage is between 8-12 VAC see the replacement parts list for a receiver PCB
assembly, and contact the Customer Service Department.
(C) The scoreboard digits light but the console doesn’t work:
(a) Check for continuity between the scoreboard and the junction box.
(b) If an open circuit is found, the problem is either the cable or a cable connection.
(c) If the continuity test checks good, check the voltage between the green wire and the white
wire in the junction box, using a voltmeter set on the 12 VAC or higher scale.
If the voltage is 0 VAC see the controller parts list for a transformer assembly.
If the voltage is less than 8 VAC consult the controller wiring diagram for instructions
on long cable compensation.
If the voltage is between 8 VAC and 12 VAC contact the Customer Service Department.
(D) The scoreboard digits light, the console works but there is no control of the scoreboard:
(a) Check the voltage between the black and red wires in the junction box with a
voltmeter set on the 3 VDC or higher scale. The voltage should read somewhere
between 2-3 VDC when the console is working properly.
(b) If the voltage is 0 VDC contact the Customer Service Department for assistance.
(c) If the voltage is correct, (2-3 VDC) check that this reading also appears at the scoreboard.
(d) If the correct voltage also appears at the scoreboard, see the replacement parts list for
a receiver PCB assembly.
(E) The scoreboard works, but some lights stay on all the time:
(a) With the main power “OFF”, switch the plug from the bad digit with the plug for a
known good digit. EXAMPLE: Plug “C” into “D” and “D” into “C” locations.
(b) Turn the power back on. If the same lamps remain lit all the time, the problem is a
shorted lamp socket. If the lamps on a different digit now stay lit all the time, the problem
is on the driver PCB assembly. See the replacement parts list for the proper
replacement part.
(F) The scoreboard works but some lights do not come on:
(a) Check for burned out lamps.
(b) Check for a broken wire or bad connection on the 12 pin connector.
(c) See the replacement parts list for the proper replacement driver board.
IMPORTANT !!!
In this scoreboard the 120 volt line is on the lamp socket all the time, and the
common is switched to turn the lamps on and off. For this reason, to avoid damage
to the equipment or personal injury, it is important to turn the main power off when
changing the lamps.
