I'm wondering if you guys could know what could be the issue? I was just outside vaping my subox mini with my mutation x V4 and hit it once and tried to hit it again and it just blinks 0.0 on my screen for the ohms and volts, if I try and throw my subtank mini on it then it works and fires like it should. I've been using this mutation on my subox for about a month now.. I took out the coils and rebuilt them and made sure the coils are touching the post to make it short out.. any answers or fixes? Thanks!
