The following tests are recommended if the unit is removed or replaced.
1. Each GEA 71 sensor input must be checked with the aircraft engine off. Make sure all
engine information systems are valid on the MFD, and that no GEA 71 related alerts appear
on the PFD. Exercise and test all discrete, analog, and/or digital inputs and check for
appropriate responses.
2. With the STBY BATT CB pulled, check to see that the STBY BATT S current from the bottom
right corner of the EIS strip on the MFD is indicating 0.0 amps. No other maintenance is
required when the indication is 0.0. If the STBY BATT current is indicating anything other
than 0.0 amps, perform the GEA 71 Standby Battery High‐Side Current Monitor Calibration
procedure.
