Thank you for your reply.

I took a picture of the current situation and attached to this post.

The black and red wires which I soldered to the battery terminals after your message were directly connected to the AC power socket. While doing that, I have noticed the 4 diodes below the AC power socket and I thought the connection points over the PCB might be close. After examining closely, I have noticed 2 cut wire tips on the right and the left side of the diodes. I connected the socket pins to those locations thinking that for AC it does not matter.

I hope I am doing ok so far.
