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