−
FOOT WARMER (NON ESSENTIAL BUS) (if installed).
3
Open the access panels:
−
21QZ
−
43AL
−
43AR
−
11DZ.
4
Disconnect wire P46A000 from Generator 2. Isolate the terminal lug and make sure that it does not
touch the structure or other metal components.
5
Connect the Maintenance box (Pt.No. T45-005) to the maintenance panel.
6
Make sure that Battery 1 and Battery 2 are connected.
Note
In this test procedure use the master warning or caution button on the glareshield to acknowledge
generated warnings and cautions.
7
Connect external power to the aircraft. Make sure that the green EXT PWR AVAIL LED on the
Overhead panel (OHP) is ON.
8
On the OHP set these switches to OFF:
−
CABIN BUS
−
AV 1 BUS
−
AV 2 BUS.
9
On the OHP set the STBY BUS switch to ON.
10
Make sure that the lower Multi Function Display (MFD) powers up.
11
Wait until the Pre-Departure Clearance mode is shown on the MFD then on the OHP set the BAT 2
switch to ON. Make sure that:
−
the pilot Primary Flight Display (PFD) powers up
−
the Battery 2 voltage is 24 VDC ±3 VDC
−
the Battery 2 current reading is negative.
12
On the OHP set the BAT 1 switch to ON.
13
On the OHP set the EXT PWR switch to ON and make sure that:
−
the blue EXT PWR ON LED is ON
−
the MFD Battery 1 and Battery 2 voltages show more than 25 VDC
−
the MFD Battery 1 and Battery 2 currents show positive.
14
Use a Multimeter (Pt.No. Local supply) to measure the voltage between RHPJB terminal T6 and
ground. The voltage reading is 0 VDC.
15
Remove the safety clip and close this circuit breaker:
−
HYD PWR (RHPJB).
16
Use a Multimeter (Pt.No. Local supply) to measure the voltage between RHPJB terminal T6 and
ground. The voltage reading is 28 VDC ±1 VDC.
17
Use a Multimeter (Pt.No. Local supply) to measure the voltage between RHPJB terminal T7 and
ground. The voltage reading is 0 VDC.
18
