Hey there,i started off by following one of a few videos on youtube. I oxidized the mesh, but after wrapping the wire around the mesh and putting one wire on the outside of the rubber stopper, one inside. then inserting the little metal piece, i thought i was ready to go after trimming it down. when i hooked it up to my zmax, it started out at 2.1 ohm. then on the next try it went down to 1.2 ohm. the zmax will not work below 1.5 ohm. the only thing i can think is maybe my wire wrap is too lose. i was having issues getting it tight. any guess, tips?
