2000 125A Ferroresonant Rectifier J85502C-1
6 - 6 Testing
Issue 8 July 1999
e. With the BAT fuse installed in the plant controller,
check for battery voltage between pin 5 of J2A and
ground.
f.
If the plant is equipped with a MCS Controller, again
on J2A, check for 15-20 volts dc between pins 35 and
31. Pin 35 should be positive with respect to pin 31.
4. Place the Battery Plant Simulator Test Set (Figure 6-1), at a
convenient location near the rectifier. Connect J2A, on the
other end of the cable from the test set, to connector P2A on
the CM2 control board mounted on the inside of the
rectifier door. Connect the red, black, blue, and white test
clips from the test set to the CM1 and CM2 boards in the
rectifier as detailed in Table 6-B. Refer to Figures 6-2 and
6-3.
