Voltage on Front Board
(All test point voltages are marked on the board)
Test the voltage from the
back board at test points
A & C.
-If the voltage is not
21
VAC
(
±
10%)
confirm that the
ribbon cable that
connects the back board
to the front board is not
damaged and that it is
seated correctly and
retest. If the retest
remains outside the
required voltage, perform
a back board test.

Cell Current on Front Board
(All test point voltages are marked on the board)
Cell Current is tested
through DC Millivolts.
Test the current from the
cell at test points H & K.
-If the voltage is higher
than 160 mVDC or less
than 120 mVDC, confirm
that the ribbon cable that
connects the back board
to the front board is not
damaged and that it is
seated correctly and
retest. If the retest
remains outside the
required voltage, perform
a back board test.
Informational Note:
20 millivolts =
1 ampere on a 1400 unit
40 millivolts =
1 ampere on a 700 unit
