Preventive Maintenance Removing and Installing Batteries: 1. Be sure all switches on the vehicle are turned OFF. 2. Disconnect negative ground cable. 3. Disconnect positive cable. 4. Unscrew bolt of holding plate with open end wrench. To reinstall batteries: 1. Place batteries in vehicle and tighten bolt of holding plate. 2. Reconnect positive cable. 3. Reconnect negative ground cable. Battery Care Regular attention to the charging system will help prolong the service life of the batteries. Here are some common causes of battery failure: Overcharge: this condition results from improper voltage regulator adjustment. It results in overheating of the battery, warped plates, and evaporation of electrolyte. Electrical System 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 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. Model 330 PB1318 3/01 – 187 –
