A. By the fact, when copper is fused a shaft of green light will be thrown off instead of a shaft of white light.
54. Q. What should be done when a green light is seen?
A. Close the throttle to turbine engine, then open slowly until a white light re-appears.
55. Q. What is the cause of the copper electrode fusing?
A. The cause of the copper electrode fusing is due to too high speed of the generator, or having lead wires connected up wrong, allowing positive current to get into copper electrode first.
56. Q. What arrangements have been made so that you cannot connect your wires wrong?
A. The positive binding post both at the dynamo and lamp have been provided with a much larger hole to receive the wire than has been made in the negative binding post, and the ends of the positive wire should always be bent or doubled back so they will just enter the receptacle in the positive binding posts, but cannot be connected to the negative binding post.
57. Q. Should the copper electrode and holder become fused until no longer serviceable out on the road, what would you do?
A. Would remove the damaged holder from the lamp and substitute a carbon, securing the substituted electrode in the bracket of lamp same as the electrode holder is held. Be sure that the end of the carbon comes up to center of reflector and does not rest on base of reflector or lamp.
58. Q. If you were running along with your light burning steady and nice, then suddenly the light began to flash badly and kept it up, where would you look for the trouble?
