2000 100A Ferroresonant Rectifier J85503A-1
Issue 6 October 1998
Testing 6 - 5
–
As an extra precaution, check for battery voltage
between ground and pin 2 (negative plant) or pin 27
(positive plant). If no voltage exists, there is a wiring
problem associated with the control cable or controller.
The problem must be found and repaired before
proceeding with testing.
–
With the BAT fuse installed in the plant controller,
check for battery voltage between pin 5 of J2A and
ground.
–
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 mounted on the inside of the
front 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 2-2 and
2-3.
Note
On J2A, pins 1, 5, 10, 15, and 20 are marked on the
connector. Pin 21 is in the row across from pin 1. Pin 40 is
across from pin 20.
