My evod BDC has stopped working on my ecig 650 mah :(

It works fine on my other battery (that came with it in a cheap starer kit) but has stopped working on my ecig 650mah. My other tanks works fine on the 650mah. I just checked it for flooding and cleaned the tank and dry burned the coils and put it all back together but it still wont go.

Any help is as always much appreciated.

 

Try pulling up the center pin on the 650 with a little flathead sctrewdriver to make sure its making contact.
