JCB C1025: Battery Voltage High Fault Condition

The system has detected a high voltage condition in the battery circuit. This may indicate an overvoltage situation that could affect the electrical system of the machine.

1. 1

   The battery voltage under load

2. 2

   The charging system output voltage

3. 3

   The connection and condition of the battery terminals

1. 1

   Measure the battery voltage

   Use a multimeter to measure the battery voltage while the machine is running and under load.

2. 2

   Inspect the battery connections

   Check for loose, corroded, or damaged connections at the battery terminals.

3. 3

   Check the charging system

   Verify the output voltage of the charging system to ensure it is within the specified range.
