Engine News, April 1989, Page 6, "Preventive Maintenance For Batteries."Reference: Special Instruction, SEHS7633, "Battery Test Procedure."The procedures that follow apply to systems of any voltage and either positive or negative ground.
Engine Starting with Jumper Cables
Batteries give off flammable fumes that can explode. This can result in personal injury.
Prevent sparks near the batteries. They could cause vapors to explode. Do not allow jumper cable ends to contact each other or the product.
Add water if necessary to cover the plates in batteries on the stalled engine.
Always thaw a frozen battery before jump starting. Frozen batteries may explode causing personal injury.
Do not smoke when checking battery electrolyte levels.
Electrolyte is an acid and can cause personal injury if it contacts skin or eyes.
Always wear eye protection when starting an engine with jumper cables.
Incorrect jump procedures can cause an explosion resulting in personal injury.
Always connect battery positive (+) to battery positive (+) and battery negative (-) to battery negative (-).
Jump only with a battery source and with the same voltage as the stalled engine.
Turn off all lights and accessories on the stalled engine. Otherwise, they will operate when the jump source is connected.
When starting from another engine, make sure the engines do not touch. This could prevent damage to engine bearings and electrical circuits.
Turn on (close) the disconnect switch on the stalled engine prior to the jump connection to prevent damage to electrical components.
Severely discharged maintenance free batteries might not fully recharge by the alternator alone after jump starting. They should be charged to the correct voltage by a battery charger.
Many batteries thought to be unusable, are only discharged. Recharge and load test to confirm true battery condition.
Use only equal voltage for jump starting. Use of a higher voltage can damage the electrical system.
Refer to Special Instruction, SEHS7633, Battery Test Procedure, for complete testing and charging information.
Engine Starting with Jump (Formerly Called "Auxiliary") Start Receptacles
Some Caterpillar products may be equipped with jump start receptacles as standard equipment. All other products can be equipped with a parts service receptacle. A permanent receptacle is then always available for jump starting.
Two mating cable assemblies are also available to jump the stalled engine from another engine also equipped with this receptacle or an auxiliary power pack. Your Caterpillar dealer can provide the correct cables in lengths for your application.
1. Make initial determination as to failure of the stalled machine to crank. Refer to Special Instruction SEHS7768 on use of 6V2150 Starting/Charging Analyzer Group. This procedure applies even if the engine does not have a diagnostic connector.2. If so equipped, place the transmission control in NEUTRAL on the stalled machine. Engage the parking/secondary brake.3. Turn the start switch to OFF on the stalled engine. Turn off all accessories.4. Turn on (close) the
