b. If voltage is below tolerance, discon-
nect wires from TB1-7 and TB1-8
and measure voltage on these wires.
If voltage on wires is below toler-
ance, refer to TM 5-6350-264-
14/10 & P on J-SIIDS Control
If voltage at Control Unit is good,
check wires for open circuits
and shorts-to-ground per instruc-
tions in TM 5-6350-264-14/1.
If voltage on wires is good, replace PC
To remove Processor PC board,
tag and disconnect wires from
TB1 and TB2. Remove screws.
Remove PC board.
To install new PC board, orient
the board so the terminal strips
are adjacent to conduit entrance
holes. Secure the PC board to
the chassis with screws. Connect
wires to TB1 and TB2.
Adjust sensitivity control per
steps in TM 5-6350-264-14/1.
c. Low voltage to
a. Set multimeter to dc volts. Connect
receiver positive lead to TB2-1 and negative
lead to TB2-2. Meter should indicate
5.3 0.5 vdc.
b. If voltage is below tolerance, disconnect
wires from TB2-1 and TB2-2 and
measure voltage on these terminals.
If voltage is still below tolerance, re-
place PC board.
To remove Processor PC board, tag
and disconnect wires from TB1
and TB2. Remove screws. Re-
move PC board.
