I purchased the subox yesterday, both occ's worked great however trying to use the RBA just gives me a 9.9ohm reading showing a short. Eventually both the occ heads gave out so I bought new Kanthal wire to try and fix the shorting problem. Now with new coils in both OCC's and the RBA i get a 9.9 ohm reading and 0.0 voltage, however the ohm's fluctuate between 4.5 to 7 ohm on the O.5 occ. I am new to vaping and this is extremely frustrating as I have cleaned the 510 connector with isopropyl alcahol, tried new wiring etc, etc. The product is legitimate Kangertech, what am I doing wrong here???
