I am having issues with making solid connections in the wiring. One of the issues is having to run a wire from the negative side of the battery (which is always the furthest away from the atomizer) and also having problems with the soldering to the atomizer housing. The atomizer housings have busted in half from sanding and reusing so there isn't much to solder a wire to, only the treads part is left. I was wondering if is possible just to run a wire from the negative side of the battery to the mod housing itself using a drill and screw if you are using a metal or aluminum mod case? That way I don't have to worry about running a wire the length of the mod or worry about soldering it to the atomizer housing?
