1.8.1 GENERAL TROUBLESHOOTING

1) Review the airframe logbook to verify if any G5 or other avionics or
electrical maintenance had been performed recently that may have
contributed to the failure.
2) Check for loose wire terminals on the circuit breaker connections on the
power wire(s) causing intermittent power connections. Also, check for
intermittent circuit breakers.
3) Have ground power put on the aircraft.
4) Turn on the G5 and record the system software version displayed on the
start up page.
5) After the system is initialized, note any Red-X's on the display or anywhere
in the configuration mode menus.
If the failure cannot be verified, proceed to the following physical inspection.
1) Power cycle the G5 or any affected LRU by removing aircraft power, waiting
30 seconds, then reapplying power.
2) Check that all connectors are fully seated, and that the jack screw
connectors are fully tightened on both sides of all connectors.
3) Check for a loose wire harness that is able to move around during flight.
This condition may cause the wire to pull on or vibrate the connector,
making intermittent connections.
