therefore can be installed with or without conduit. Consult
section
6 for junction box and scoreboard wiring.
2.5 Electrical Connections
This scoreboard requires one 110 V. 20 Amp AC circuit for the
exclusive use of the scoreboard.
IMPORTANT
I
I To protect the MP-2001 Control from damage,it is advisable that you I

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.
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 Guide
(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 "off" remove the cover over the
controller assembly.
(b) Check all connections.
(c) Turn main power "on1'.
(d) If board still doesn't light check the transformer
voltage going to the Reciever PCB 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 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 then 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 V 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. (2-3 VDC when working properly)
(b) If the voltage is 0 V contact the service department
. .
for assistance.
-
(c) If the voltage is correct (2-3 V) 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 llC1fin tfD1fand "D" in "CI1 locations.
(b) Turn the power back on. If the same lights remain
lit, the problem is a shorted lamp socket. If the
lights now stay on in a different digit the problem
is the driver board. See the replacement parts list
for the proper replacement driver board.
(F) The Scoreboard Works But Some Lights Do Not Come On
(a) Check for burned out lamps.
(b) Check for broken wire or bad connection on 12 pin
connector.
(c) See the replacement parts list for the proper
replacement driver board.
