INTRODUCTION
The MoD BoX Jukebox incorporates several modules which plug in for rapid
service.  The most likely cause of jukebox problems are:
1.
Continuous or intermittent opens in a harness.  The cause can be
wiring, a terminal, or a bad terminal crimp.
• Check that all plugs are firmly seated.
• Check that connector pins are not bent, broken, or pushed through
the back of connectors when mated.
2.
A defective module.  Troubleshooting procedures are directed at mod-
ule replacement, not repair.
A summary of the functions for each of the jukebox’s replaceable modules is in
Section 1.
The troubleshooting topics presented in this section are:
• The MoD BoX’s LED’s are described and can help you isolate a
problem.
• Wiring diagrams (see Figures 7-2 through 7-5) to help you isolate
the problem to a harness or a module.
• Modular Troubleshooting Charts that list the Trouble, Symptom, and
Probable Cause.
