Trickle-charger not working (pics included) - Make an Arduino-Controlled Robot

After following the book my trickle charger just doesn't seem to be working after an eight hour charge attempt didn't do anything to the batteries. The power switch was on at the time of the charge attempt as instructed in the book. I tested my AC/DC wall adapter ( with a connection to the Arduino Leonardo and it powers it just fine.

I'm led to believe that perhaps I misinterpreted the instructions and diagrams in the book and this is why it's not working. Could the author possibly review these photos and see if he notices an error in my implementation? Thanks!
