2.18 electrical System
Your truck is equipped with either a 12 volt or
24 volt DC electrical system depending on your
location and the chassis manufacturer. The cutter
electrical system is totally isolated from the truck
electrical system.
The system is equipped with two heavy duty Main
circuit breakers on the side of the battery compart-
ment on the passenger side of the chassis. These
breakers protect the cutter system DC circuits
and can function as Main disconnect switches to
deactivate the system.
Main Circuit Breakers
Two heavy duty circuit breakers, a 90 amp and a
70 amp breaker, are connected directly to battery
and supply electrical power directly to the outside
terminal box (OTB) accessory fuse panel and in-
line fuses or circuit breakers for accessory circuits
connected to the Main breakers. The breakers
must be on to power the cutter electrical system.
Each Main circuit breaker is equipped with a yellow
indicator/reset lever that indicates the status of
the breaker (ON or OFF/TRIPPED) and is used to
reset the breaker if it trips or to turn the breakers
and electrical system off.
These are heavy duty circuit breakers that typi-
cally trip only when there is a serious fault in
the system. If a Main breaker trips, you should
find and correct the problem before resetting the
breaker. The breaker is reset by moving the yellow
lever to the ON position.
Each Main breaker can be used as a Main discon-
nect switch by manually moving the yellow lever
to the OFF or ON position. Move the lever to the
ON position to activate the electrical system. Move
the yellow lever to OFF position to deactivate the
electrical system.
