So I'm new to rebuildables. I think I have the general idea but the one question that Im left with is when do I test the coil? Like I've got a little ohm reader, I've got a couple regulated mods, I've got pre coiled coils and the berserker mtl rta and I think I understand from videos the general steps to take but where I'm confused is when do I test the coil and what am I looking for? I don't want to fry my mod..or do something dangerous. Is there a step-by-step guide? I've tried searching for it but I fear that my forum skills are lacking. I know that there's going to be a lot of experimentation but first and foremost I want to make sure that I'm not going to destroy my equipment.
