Reuleaux in TC with a dual 23ga NiFe52 everything works fine on first connection and until the mod goes to sleep. When I wake it the coil is reading .10 instead of the .13 it's starts off with and the mod will not get hot it says it's at max temp 400 but barely any steam is coming off the coils. If I pull the batteries it will reread and work fine till asleep again. What is my issue???
