2000 50A Ferroresonant Rectifier J85502B-1
6 - 6 Testing
Issue 6 May 1999
d. With the BAT fuse installed in the plant controller,
check for battery voltage between pin 5 of J2A and
ground.
e. If the plant is equipped with an 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, which is 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.
