Check of the CE inhibiting diodes

Check of the CE inhibiting diodes

The inhibiting diodes in the CE vehicle network can be checked as follows:

• Stop all work on the vehicle.
  
• Disconnect the battery charger.
  
• Start the engine (operating mode petrol or hydrogen).
  
• Measure the voltage of the vehicle battery.
  
• Measure the voltage of the CE batteries.
  

The inhibiting diodes are OK if the measured battery voltage of the CE batteries is 0.2 V to 0.3 V lower than the measured battery voltage of the vehicle battery.
