A. When there is short circuit, the engine will labor heavily, run slow
with a large volume of steam blowing at the exhaust, there will be no
light shown either at the arc or cab lamps, and the carbon point and cab
lights will only show a dull red or go entirely out.
35. Q. How will the equipment act when the circuit is broken, either by
a broken disconnected wire or a burned-out carbon?
A. With a broken circuit the engine will run noiselessly and fast with
very little steam blowing at exhaust and no light will be seen at the
arc or on cab lights.
36. Q. If the insulation on the cab wires is worn off until your two
wires can come together either directly or through the medium of some
metallic substance, what would occur?
A. A short circuit would result that would put out all of your lights.
