Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Determine if a code is active or logged.
Codes
Result: A -3 code is active or logged.
Proceed to Test Step 2.
Result: A -4 code is active or logged.
Proceed to Test Step 3.
2. Check the Charging Circuit
Charging Circuit
Result: The charging system is OK.
Proceed to Test Step 3.
Result: The charging system is NOT OK.
Repair: There is a problem with the charging system. Refer to Special Instruction, REHS0354, "Charging System Troubleshooting" for additional information.
Verify that the repair eliminated the problem.
3. Inspect the Batteries
A. Charge the batteries, if necessary. Refer to Special Instruction, SEHS7633, "Battery Test Procedure" for additional information.
B. Load-test the batteries. Refer to Special Instruction, SEHS9249, "Use of 4C-4911 Battery Load Tester for 6, 8 V and 12 V Lead Acid Batteries" for additional information.
Batteries
Result: The batteries pass the load test. The measured voltage is between 11.5 VDC and 13.5 VDC for a 12 V system. The measured voltage is between 23.0 VDC and 27.0 VDC for a 24 V system.
Repair: Verify that the "System Operating Voltage Configuration" is correctly configured in the Engine ECM configuration parameters.
Verify that the repair eliminated the problem.
Result: The battery voltage is low or the battery did not pass the load test.
Repair: Repair or replace the batteries.
Verify that the repair eliminated the problem.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
