Hello. The charger (type as in the topic) does not work. I checked the smd elements around the converter on the primary side and the / g markings are ok. Secondary side semiconductors also ok. The converter does not work, does not heat up, supply voltage is approx. 13v. Elko on the gretz bridge is charged and holds the voltage for quite a long time, although it should discharge after some time after disconnecting the power supply.
I analyzed the transformer from the primary side, there are three windings, there is a transition between 1 and 2 and a gap in the third. I do not know if this is the output of the split primary winding and there is a break or it is a screen winding.
