3. Fault Confirmation__________________
A. Test
(1) Do the Operational Test of the Generator Line Contactor (GLC-1) Opening in the Smoke Procedure (Ref. AMM TASK 24-22-00-710-001).
NOTE : During the job set-up of the operational test, the left and
____ right wing-tank fuel-pumps 1 are supplied by AC BUS 1 and DC BUS 1 (the normal operational supplies from engine 1).
During the procedure of the operational test, when the generator line contactor (GLC-1) is open (GEN 1 LINE P/BSW released out), the left and right wing-tank fuel-pumps 1 are supplied from the electrical ground power unit through the transfer circuit.
