I have had this setup for about a month now with no problems.  I recently started dripping but I like to go back to my protank once in awhile also.  But since I have been doing this my protank won't fire properly most of the time.  It usually works when I replace the coil but the moment I take the tank back off to fill it the protank won't register (non).  And yes I have mixed up the coils and tried different ohms and boxes of coils.  What is the problem, my MVP2, the protank, or do I just have lots of crappy coils.
