after adjusting the center pin on my serpent my mods suddenly won't read the ohms correctly. the readings are +.1 ohm and higher and no longer hold steady. as there's a screw slot in the pin i assumed it was able to be adjusted. every time i fire it on my vtc mini or koopor mini i'm asked if i have a new coil. i really like the tank and i hope i didn't break it. has anyone ran into this problem? i admit i didn't read thru it's own thread entirely, but i hadn't seen this mentioned.
