Thank you for the reply!

Can't wait till the rest of the parts arrive :)

I will have to check the chip for shortcuts first. I fear I used too much flux.

I have a question about the v2 mainboard. I just finished the mainboard. I did the voltage checks and everything seems all right, except the 3V battery. I have 5V on the 7805 and 4,8 on the VCC of both chips. I also have 220V on the high voltage part.

When I measure the battery it self it has 3V. When I insert the battery in the holder I have 0V, measured on the battery holder itself. On the RTC Vbat there is also 0V.

I measure a resistance of 1kOhm between the +- of the battery holder, so there is no shortcut.
