Install fuse FS 6 (WP 0401). Disconnect cab power distribution wire harness siren
control connector MP2. Turn battery disconnect switch to ON position (WP 0007). Put
EMERG MASTER switch to on position (WP 0004). With a test lead set, check for 22 to
28 VDC between wire 1637 (red) at cab power distribution wire harness siren control
connector MP2, terminal F and a known good ground.
If 22 to 28 VDC are not present, repair wire 1637 in cab power distribution
harness if repairable (TM 9-2320-325-14&P), or replace cab power
distribution wire harness and block (WP 0441).
Step 7.
Turn battery disconnect switch to OFF position (WP 0007). Put EMERG MASTER

power distribution wire harness wire 1640 (black) from cab power distribution wire
harness siren control connector MP2, terminal D to a known good ground.
If there is no continuity, repair wire 1640 in cab power distribution wire
harness if repairable (TM 9-2320-325-14&P), or replace cab power
distribution wire harness and block (WP 0441).
