The following fault was present: • Car no longer charging at the 400 volt charging station Public • Charging condition of the main battery 14% • The orange key and the warning lamp drive battery is on!!! What did I do: • The 12 volt battery was empty. • Have + and – solved from the battery • Have the 12 volt battery recharged • Battery + and – again connected • Now only the warning lamp electric motor • 12 volt battery is on again and waits for one hour • Battery + and – again connected • The orange key and the warning lamp drive battery is on again!!! • The warning lamp electric motor is off again. Why the 12 volt battery has to be unloaded again and again. So I did the following: • Battery in quiet mode measured 12,6 volts. I shut the doors. • Doors on and ignition on I measured 14.6 volts • Doors on and ignition out he only has 10 volts. That’s still to be communicated to the main battery? ?? • After that the power supply has been connected to the car always after 7 minutes. There are no silent consumptions before. • Stop lights. But stop the warning of the alarm call of the alarm! The alarm is again! The alarm call of the alarm of the alarm of the main battery was again.
