I recently built a dual coil on my igo-l the ohm reading is 1.5 and it worked really good. Today i noticed that i wasnt getting as much flavor or vapor. I took out the cotton and dry burned it. I realized that one of the coils barely lights up. The other coil lights up fast and glows red (inside to out) and when its fully glowing the other one starts to glow. The bad coil takes a while to heat up. Please help me
