Operation
WARNING
Do not check battery condition by shorting
(flashing) across terminals. Failure to observe
this warning could result in personal injury
and/or damage to the vehicle.
When working around the terminals and battery, use extra care
to avoid shorting. A good practice is to use insulated pliers and
screwdrivers.
Battery Disconnect Switch
This optional switch is used to prevent the batteries from
discharging. When a vehicle is not going to be operated for
several days, this switch can be used to shut off the system
so the electrical components on the vehicle, if left on, will not
discharge the batteries.
These features have options that provide a key or lever
operated battery disconnect switch, which may be cab mounted
or mounted on the battery box. There are also options that
completely disconnect the batteries or disconnect everything
except the charging circuits.
Circuit Breakers, Fuses, and Fusible Links
WARNING
Electrical circuits are designed with a particular
wire gauge to meet the fuse and circuit breaker
current rating. Do not increase size of fuse or
circuit breaker or change type of breaker supplied
with your truck. To do so could cause wiring to
overheat and possibly burn, resulting in a fire,
which could cause property damage, personal
injury, or death.
Electrical circuits are protected either by the body controller,
circuit breakers, fuses, or fusible links. For the size and location
of circuit breakers, fuses, and fusible links, please refer to
the Maintenance Intervals And Specification section of this
manual.
Fusible links consist of a length of lighter gauge wire in a circuit.
In case of a short or overload, the fusible link opens (burns out) to
protect the remainder of the circuit. Repair consists of splicing
in a new fusible link with the same gauge wire as the opened
fusible link.
Circuit breakers interrupt the circuit when an overload or short
occurs.
Manual circuit breakers (Type III) can be reset by
depressing the reset button on the breaker.
Headlamp and
wiper circuits are protected by the Body Controller Virtual Fusing
system. Type II circuit breakers will reset if the short is removed
from the circuit.
The various electrical units in the cab and engine compartments
are protected by either fuses or circuit breakers. The power
