XZBMW  Eltek Multicharger 900 charger problem
Hi guys,
I have strange problem with the Eltec multicharger 900. At once it stopped charging. The electronics detect that the battery is connected but the charging procedure doesn´t start. On the display I can see the actual battery voltage but current doesn´t flow. The yellow diode is flashing. 
In user manual I have read that this signs that Multicharger is not contacted.
I already restored factory settings on the charger but no effect.

Has anybody met and solved this kind of problem?

I would be thankful if anybody has the wiring schematic to help me out.

BR Tom

What program are you using for charging? When on power supply one program was intended for power supply without battery connected to car. When MC 900 detects voltage/current on car side cuts power off.
Link for user guide and firmware update to get LiPo charging.
Bmw part number for update cabel 81 39 2 444 931

Good luck!
