R  A. Check of the ENG 1 Fire Extinguisher Bottle 1 
R R  NOTE : Two persons are necessary to do this check: one person to read the____ value on the multimeter, the other to use the Allen wrench.
R R  (1) On the electrical connector 473VC: - use a multimeter to do a check of the continuity between the pin 4 and the A/C ground.
 (2) On the fire extinguisher bottle 6WE1: 
R R  CAUTION : DO NOT USE FORCE WHEN YOU TURN THE ALLEN WRENCH. IF YOU USE_______ FORCE, YOU CAN CAUSE DAMAGE TO THE PRESSURE SWITCH.
R  - engage the Allen wrench (3/32 in. hex key) into the test point (Allen key) - turn the Allen wrench clockwise (by 10 degrees approximately) until you can feel a force, and hold it in this position.
R R  (3) On the electrical connector 473VC: - make sure with the multimeter that there is no continuity between the pin 4 and the A/C ground.
