Light on charger blinking periodically

Alright so I just got my neopixel saber pre wired. The sound is marvelous. The led strips are bright. Weird thing is when I plug in my charger, the red charging led only lights up sometimes, but it seems to be charging. I've got good connections on my rc port pads I believe (at least according to my multimeter). I'm wondering if anyone else has seen this happen or should I really go ahead and tear it down to see what's up. Also, there aren't any bad smells or weird sounds when the charger is in. Thanks guys.

Well...uhh...I fiddled with the connectors and now it works...I dunno what that was about.
