Hey guys...I recently bought a new heater 12vdc version (2 weeks ago) and have only used it three times thus far for a total of maybe 4-6 hours of heating. I run it off a 3s orion 4700mah pack. Everything worked great the first couple of times...but now it turns on and off and won't stay heated up. When I wiggle the connecting wire around it comes back to life, but then goes out again. It is difficult to find a position for it to stay powered up. It appears to be some sort of wire connection issue.

Anybody else have this problem? If so, how did you resolve it? Send it in for a replacement?
