PR001
BATTERY VOLTAGE
NOTESCheck that the battery terminals are correctly tightened.
Check the consistency between the battery voltage measurement from the multimeter and the value of PR004
Battery voltage.
Engine stopped: 11 V < X < 13.5 V.
Engine running: 10.5 V < X < 16 V.
If the voltage values are not consistent (greater than 0.3 V difference between the 2 values), check the connection
between the + battery feed and the Protection and Switching Unit.
If the values are consistent, run fault finding on the battery and charging circuit (see Technical Note 6014A,
Checking the charging circuit, 16A, Starting - Charging).
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
