ADAPTER GP 1909940 - Caterpillar

This machine has a 24 volt starting system. Use only the same voltage for jump starting. The use of a higher voltage will damage the electrical system.
Engines with air start - If the power receptacle is unable to be used, use jump-start cables to charge the batteries. The batteries provide a 24V ECM power supply during engine starting. For more information on the power receptacle, refer to Operation and Maintenance Manual, "Power Receptacle".Use of Jump-Start Cables
Determine the reason that the engine will not start. Refer to Special Instruction, REHS0354, "Charging System Troubleshooting".
Move the transmission control to the P position on the stalled machine. Move the hoist control to the HOLD position.
On a stalled machine, turn the start switch key to the OFF position. Turn off the accessories.
On a stalled machine, turn the battery disconnect switch to the ON position.
Move the machines together in order for the cables to reach. DO NOT ALLOW THE MACHINES TO CONTACT EACH OTHER.
Stop the engine of the machine that is being used as an electrical source. When you use an auxiliary power source, turn off the charging system.

Check the battery caps for correct placement and for correct tightness. Make these checks on both machines. Make sure that the batteries in the stalled machine are not frozen. Check the batteries for low electrolyte.
Connect the positive jump-start cable to the positive cable terminal of the discharged battery.Do not allow positive cable clamps to contact any metal except for battery terminals.
Batteries in series may be in separate compartments. Use the terminal that is connected to the starter solenoid. This battery is normally on the same side of the machine as the starter.
Connect the positive jump-start cable to the positive terminal of the electrical source. Use the procedure from Step 9 to determine the correct terminal.
Connect one end of the negative jump-start cable to the negative terminal of the electrical source.
Make the final connection. Connect the negative cable to the frame of the stalled machine. Make this connection away from the battery, the fuel, the hydraulic lines, or moving parts.
Start the engine on the machine that is the electrical source. Also, you can energize the charging system on the auxiliary power source.
Allow the electrical source to charge the batteries for 2 minutes.
Attempt to start the stalled engine. Refer to Operation and Maintenance Manual, "Engine Starting". See the beginning of this topic.
Immediately after the stalled engine starts, disconnect the jump-start cables in reverse order.
Conclude with a failure analysis on the starting charging system. Check the stalled machine, as required. Check the machine when the engine is running and the charging system is in operation.Refer to Special Instruction, SEHS7633, "Battery Test Procedure" for complete testing and charging information for the batteries.Engine Starting with Auxiliary Start Receptacle ( If Equipped with Type 2 24V Power Receptacle)
When starting from another machine, make sure that the machines do
