| During start-up of the circuit shown in figure "B" of the illustration, it is noted that the ends of component "4" alternately glow and become dark without the tube illuminating. What is the most probable cause for this condition? Illustration EL-0081 |
| A) component "5" contacts are opening and closing thus prohibiting sufficient current flow |
| B) component "2" is loose and due to the ship's vibrations makes and breaks contact |
| C) component "3" is shorted and therefore unable to produce the high voltage required to start the lamp |
| D) the power system's voltage is fluctuating in and out of the range necessary for proper operation |
