Section: 7 Troubleshooting
Introduction
The Grand STAR Jukebox incorporates several modules which plug in for rapid service.
The most likely cause of jukebox problems is:
1. Continuous or intermittent open circuits in a harness. The cause can be broken or cut
wires, a damaged 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 module replacement,
not repair.
