b.
50/60 Hz Module. See Figure 6-32.
(1)
Start the engine and operate at 1800 rpm and no load.
(2)
Using a multimeter set to 0 to 2.5 V dc scale, measure voltage from terminal J to terminal 3.
(3)
Multimeter should indicate a slight positive (+) voltage from terminal J to terminal 3.
(4)
Set FREQUENCY SEL. SW. S118 to 50 Hz.
(5)
Multimeter should indicate zero volts.
(6)
Replace a 50/60 Hz module which fails this test.
WARNING
High voltages and currents appear at load sharing panel A104 terminals 1
through 9. Observe safety precautions applicable to maintenance on high
voltage equipment Failure to do so may result in injury or death.
