CORRECTIVE ACTION Continued
Remove screw securing ground wire. Check ground wire for continuity by placing red lead of mul-
timeter in socket G and black lead on ground wire terminal. If continuity is present, go to step 8. If
continuity is not present, repair/replace ground wire of smoke grenade launcher system wiring harness
(see WP 0241 00).
Reconnect ground wire. Place jumper wires from pin G to socket G and from pin C to socket C. Place
red lead of multimeter on pin B and black lead to ground. Turn MASTER and ARM SMOKE switches
ON, push RIGHT switch, and check for voltage. Turn MASTER and ARM SMOKE switches OFF. If
voltage is present, go to step 9 for right dischargers, and step 10 for left dischargers. If voltage is not
present, replace FIRE SMOKE box assembly (refer to TM 3-1040-266-20&P).
