LED on SSC-32 doesn't light up =( fix?

Well, after finishing the assembly, I connected the computer to the Arduino with a USB cable and its LEDs where on.
Then I plugged the battery to the SSC-32 but the green LED didn’t go on.
First I was getting a low voltage in VS1 (where I connected the battery) so I charged it (I see 6V marked on the battery but when I unplugged it, it had ˜7V and the charger was still red).
I measured a voltage of 6.7V on VS1. I think the threshold is 5V so it should be ok regarding power, isn’t it?
Are there other components that I could measure to check if the SSC-32 controller is damaged?

Your SSC-32 setup looks ok. Did you connect a 9V battery to VL? It looks like you have the BotBoarduino correctly connected to the SSC-32 (so the 9V battery powers both of their microcontrollers), however the BotBoarduino itself does not provide the necessary voltage to run the SSC-32 - you need the 9V battery. On the SSC-32 you correctly removed the VL=VS jumper, so by default the 6V battery pack would not power the SSC-32’s logic circuit.

it was that, I was missing the 9V battery. I’m new in this and I thought that was for an alternative power source.

Thanks for your answer!
