My teen loves his stunt saber but May 4th we were swinging out sabers around and his stopped lighting up. We put in new batteries and it worked again for 10 minutes before dying again. Looking to learn how to take the wiring out and solder it together if it's a loose connection. I found this link, is this what I need to fix it? Is there a video tutorial that I can follow?
Thanks in advance.
