STARTING FUSE AND BATTERY
SWITCH BOX
Starting Fuse and Battery knife switch box is located on the left side of the
Locomotive.
The Box includes the equipment described in the following paragraphs:
1.
BATT SWITCH (Battery Knife Switch):
When this switch is closed,
it connects the Locomotive Batteries to the Locomotive low voltage
electrical system. The Battery switch must be closed at all times
during Locomotive operation.
2.
STARTING FUSE:
The 800 Amps starting fuse is in use only during
Diesel Engine starting. Battery current flows through fuse and the
starting contactor to the starting Motors. The starting fuse protects
the Motors from current overload.
A defective starting fuse can be detected when attempting to start the
Engine. If the Engine start switch does not crank the Engine, then check the
fuse.
