This is new. I have a fogger and have built coils of varying resistance with no issues. I purchase a Russian 91 and build an 8/9 wrap Microcoil on 28 gauge kanthal using a 5/64 drill bit. I tie it down to the posts and doesn't appear that anything is overlapping but it won't read resistance on my ohm reader or provari. The provari displays OP. Any ideas? Done two coils now and the same thing happens.
