So I'm having some issues with my vape acting up. I have a mechanical mod, dotmod and petri atomizer. My issue is this: sometimes when I goto vape it will start to vape then cool in the middle of hitting, or the battery on the negative end IE the button gets hots, or it doesn't fire and battery heats, or it works just fine. I'm using 3 loop braided 30 gauge nichrome coils. Its very frustrating and started off just occasionally and has grown to very often. I've tried changing pins in the petri atomizer as it uses a floating pin. I've tried loosening the button a little, tightening the coil posts, changing the position of my finger to different spots on the button, and changing batteries. I even have a spare button and tried changing it. I use 35a mxjo and efest batteries and I never run them all the way dead. VERY FRUSTRATING! Could it be a short in my coils? I've read about mod shorts or atomizer shorts...any ideas?
