BRACKET AS-FAN 1007615 - Caterpillar

First, determine the reason it is necessary to start with power from an external source. Refer to SEHS7668 for information on using the 6V-2150 Starting/Charging Analyzer Group.If the installation is not equipped with a backup battery system, an external electrical source may be required for starting.Many batteries which are considered unusable are still rechargeable. Severely discharged maintenance free batteries might not fully recharge from the alternator alone after jump starting. The batteries must be charged to the proper voltage with a battery charger. For complete information on testing and charging, refer to SEHS7633, the Battery Test Procedure. The Special Instruction is available from your Caterpillar dealer.Engines installed without engine-to-frame ground straps can be damaged by electrical discharge.In order to prevent electrical discharge damage, make sure the engine's electrical system has an engine-to-frame ground strap.For engines which have the alternator connected to an engine component, the ground strap must connect that component to the frame.Some engines have starter-to-frame ground straps. Many of these starters have electrical insulation systems and are not electrically grounded to the engine. For this reason, the starter-to-frame ground strap may not be an acceptable engine ground.If the engine is not electrically connected directly to the rails through mounting bolts, install a separate ground strap. Refer to the Electrical Schematic for your engine, or consult with your Caterpillar dealer.Your engine has a 12 or 24 volt starting system. Use only the same voltage for boost starting. Use of a welder or higher voltage will damage the electrical system and is not recommended.Refer to the following instructions to properly jump start the engine.
When using an external electrical source to start your engine: turn the START switch off, remove the key, and turn off all electrical accessories before attaching cables.When using jumper cables always connect the POSITIVE (+) cable to the POSITIVE (+) terminal of the battery connected to the starter solenoid. Connect the NEGATIVE (-) cable from the external source to the starter NEGATIVE (-) terminal. If not equipped with a starter NEGATIVE terminal, connect to the engine block.Do not reverse the battery cables. The alternator can be damaged. Attach the ground cable last and remove first.
1. Connect one end of the cable to the POSITIVE (+) terminal of the battery being started. Connect the other end to the POSITIVE (+) terminal of the power source.2. Connect one end of the other cable to the NEGATIVE (-) terminal of the power source. Connect the other end to the starter NEGATIVE (-) terminal or to the engine block. This prevents potential sparks from igniting combustible gases produced by some batteries.3. Start the engine.4. After the engine starts, disconnect the cable from the starter NEGATIVE (-) terminal or engine block. Disconnect the other end from the NEGATIVE (-) terminal of the power source.5. Disconnect the cable from the POSITIVE (+) terminal of the battery on the engine being started. Disconnect the cable from the POSITIVE (+) terminal of the power source.Engine Operation
Proper operation and maintenance are key factors in
