2.3 Data Cable Installation
The MP-41 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.
2.4 Electrical connections
This scoreboard requires one 120 V. 15 AMP AC circuit for the exclusive use of the scoreboard.
IMPORTANT !!!
To protect the MP-3000 control from damage, it is advisable to disconnect the
control and store in a dry secure area when not in use.
NOTE
This equipment is ETL (Electronics Testing Laboratories) CSA and NRTL approved
and complies with the requirements in part 15 of the FCC rules for a class A
computing device. Operation of this equipment in a residential area may cause
unacceptable interference to radio and television reception, requiring the operator to
take whatever steps are necessary to correct the interference.

4. MAINTENANCE AND TROUBLESHOOTING
4.1 Introduction
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.
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.
4.2 Test Equipment
A simple analog or digital voltmeter will be sufficient 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
7

(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.
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.
8

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
proper replacement part.
(F) The scoreboard works, but some lights do not come on.
(a) Check for burned out lamps.
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.
(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.
