6 - 6 Testing

Testing Off
Line
The following tests involve use of the test load and a Battery
Plant Simulator Test Set. Refer to “Test Load Connection”
earlier in this section for the procedure to connect a test load, and
to “Battery Plant Simulator Test Set” and “Initial Conditions for
Testing Off Line”, both earlier in this section, for a Battery Plant
Simulator Test Set.
If the rectifier fails any of the following off line tests, replace
the CM2 control board as described in “Replace CM2
Control Board” in Section 8, Spare Parts and Replacement
Procedures, and begin testing again.
Startup
1. Turn on the ac supply to the rectifier. The PWR lamp on
the test set should light brightly. If it does not light
properly, check the connection of the two small red and
black clip leads. They may be reversed or otherwise
incorrectly connected. These leads provide the operating
voltages in the test set, and the red lead should be
approximately 27 volts dc with respect to the black lead.
2. The PWR lamp should remain lit during the remaining
tests as long as the ac supply is turned on.
3. Set the test meter to the 100 volts range, and connect it to
the Reg jacks on the bracket of CBA1. These jacks are the
