Regional Haul Model Operator's Manual - Peterbilt Motors Company

PREVENTIVE MAINTENANCE
Undercharge: the voltage regulator is malfunctioning or
is improperly adjusted, the drive belt is slipping, or your
vehicle has undergone long periods of standing idle or
short distance driving. These conditions result in battery
plates becoming covered with a hard coating.
Vibration: loose battery hold-downs may cause battery
plate failure.
Short Circuits: these discharge the battery by draining
electricity.
Dirty or Loose Connections: improper connections may
stop the flow of electrical power to and from the battery.
Jump Starting Vehicles
ELECTRICAL SYSTEM
However, if your battery is discharged (dead), you may be
able to start it by using energy from a good battery in
another vehicle. This is termed “jump starting.” Be sure to
follow the precautions and instructions below.
WARNING! Batteries contain acid that can
burn and gases that can explode. Ignoring
safety procedures can cause you or others to
be killed or badly hurt.
WARNING! Never jump start a battery near
fire, flames, or electrical sparks. Batteries
generate explosive gases that could explode
causing death or serious personal injury.
Keep sparks, flame, and lighted cigarettes
away from batteries.
Because of the various battery installations and optional
electrical systems, Peterbilt does not recommend that you
attempt to jump start your vehicle. If you have a battery
problem, it is best to contact a Peterbilt Dealer or a reputable
towing service.
