BATTERY SYSTEM - SERVICE INFORMATION
DESCRIPTION
This vehicle is equipped with a single 12-volt battery. All of the components of the battery system are located within the engine compartment. The battery system for this vehicle covers the following related components:
- Battery (5) - The storage battery provides a reliable means of storing a renewable source of electrical energy within the vehicle.
- Positive Battery Cable (8) - The positive battery cable connects the battery positive terminal post to the vehicle electrical system, starter and alternator.
- Negative Battery Cable (4) - The negative battery cable connects the battery negative terminal post to the vehicle electrical system through body, chassis and engine grounding points.
- Battery Holddown (6) - The battery holddown hardware secures the battery in the battery tray in the engine compartment.
- Battery Tray (7) - The battery tray provides a secure mounting location in the vehicle for the battery and an anchor point for the battery holddown hardware.
For battery system maintenance schedules (Refer to LUBRICATION & MAINTENANCE/MAINTENANCE SCHEDULES - DESCRIPTION). (Refer to LUBRICATION & MAINTENANCE/JUMP STARTING - STANDARD PROCEDURE) for the proper jump starting procedure. The battery must be fully-charged before any battery system diagnosis or testing procedures can be performed.
OPERATION
The battery system is designed to provide a safe, efficient, reliable and mobile means of delivering and storing electrical energy. This electrical energy is required to operate the engine starting system, as well as many of the other vehicle accessory systems for limited durations while the engine and/or the charging system are not operating. The battery system is also designed to provide a reserve of electrical energy to supplement the charging system for short durations while the engine is running and the electrical current demands of the vehicle exceed the output of the charging system. In addition to delivering, and storing electrical energy for the vehicle, the battery system serves as a capacitor and voltage stabilizer for the vehicle electrical system. It absorbs most abnormal or transient voltages caused by the switching of any of the electrical components or circuits in the vehicle.
CLEANING
The following information details the recommended cleaning procedures for the battery and related components. In addition to the maintenance schedules found in this service manual, (Refer to LUBRICATION & MAINTENANCE/MAINTENANCE SCHEDULES - DESCRIPTION) it is recommended that these procedures be performed any time the battery or related components must be removed for vehicle service.
1. Clean the battery cable terminal clamps (2) of all corrosion. Remove any corrosion using a wire brush or a post and terminal cleaning tool (1), and a sodium bicarbonate (baking soda) and warm water cleaning solution.
2. Clean the battery tray and battery hold down hardware of all corrosion. Remove any corrosion using a wire brush and a sodium bicarbonate (baking soda) and warm water cleaning solution (2). Paint any exposed bare metal.
3. If the removed battery is to be reinstalled, clean the outside of the battery case (3) and the top cover with a sodium bicarbonate (baking soda) and warm water cleaning solution (2) using a stiff bristle parts cleaning brush (1) to remove any acid film. Rinse the battery with clean water. Ensure that the cleaning solution does not enter the battery cells through the vent holes. If the battery is being replaced, confirm that the replacement battery is the correct size and has the correct ratings for the vehicle.
4. Clean the battery thermal guard with a sodium bicarbonate (baking soda) and warm water cleaning solution (2) using a stiff bristle parts cleaning brush (1) to remove any acid film.
5. Clean any corrosion from the battery terminal posts with a wire brush or a post and terminal cleaner (1) and a sodium bicarbonate (baking soda) and warm water cleaning solution.
INSPECTION
The following information details the recommended inspection procedures for the battery and related components. In addition to the maintenance schedules, (Refer to LUBRICATION & MAINTENANCE/MAINTENANCE SCHEDULES - DESCRIPTION), it is recommended that these procedures be performed any time the battery or related components are removed for vehicle service.
1. Inspect the battery cable terminal clamps for damage. Replace any battery cable that has a damaged or deformed terminal clamp.
2. Inspect the battery tray and battery hold down hardware for damage. Replace any damaged parts.
3. Slide the thermal guard off of the battery case, if equipped. Inspect the battery case for cracks or other damage that could result in electrolyte leaks. Also, check the battery terminal posts for looseness. Batteries with damaged cases or loose terminal posts must be replaced.
4. Inspect the battery thermal guard for tears, cracks, deformation or other damage. Replace any battery thermal guard that has been damaged.
5. Inspect the battery built-in test indicator sight glass (if equipped) for an indication of the battery condition. If the battery is discharged, charge as required, (Refer to 8 - ELECTRICAL/BATTERY SYSTEM/BATTERY - STANDARD PROCEDURE - BATTERY CHARGING).
