.3 Observe from LG-89308 that the Diesel Generator Fuel Oil Day Tank is full.

.4 After 15 minutes, record the discharge pressure for P-888C from PI-88803 and the running current at 2B114.

.5 Place the " Auto-Off-Hand" control switch of P-888D in "0FF".

.6 Place the " Auto-Off-Hand" control switch of P-888D in " HAND".

.7 After 15 minutes record the discharge pressure of P-888D from PI-88804 and and the running current at 2B115.

.8 Record the pressure differential across strainers Y-88811 and Y-88812 from PDI-88814.

.9 Place the " Auto-Off-Hand" control switch of P-888C and P-888D in "AUT0".

.10 Diesel Generator Fuel Oil System is now in the standby mode.

.2 Starting and synchronizing the "B" Diesel-Generator.

.1 Record the beginning elapsed running time of the "B" Diesel-Generator.

.la Check the crankcase oil level (the oil icyc1 should be at or above the FULL cark).

.lb Check engine coolant level (level should'be in the surge tank gage glass within the appropriate marks).

.2 Verify the "B" Diesel-Generator is in standby in accordance with 4.1 of OP A.31.
