Hey, So i purchased a Topside single battery mod about 2 weeks ago and it was working fine until last night. When i pressed the fire button and it says shorted. And nothing will fix it So i changed the coil, checked the battery and used a diffrent one, tried a different RDA, cleaned it, and everything in between and nothing changes it. My coil and battery work fine on other mods meaning that the mod itself is having issues. It at first didn't read the ohms of my RDA at all but now is reads it at .01 when it should be about .30 I took it to my local vape shop and they tried all the same stuff and also don't know how to fix it. Any other ideas? Thanks.
