Ok out of two Foggers one is working great other than the taste from the insulator. The other one was shorting straight out of the box and I have taken it apart and put it back together probably near 30 times, each time trying different insulators in different spots, and even removing and reseating the whole positive pin. I did try using the half o-ring under between the base assembly and that double post middle piece. No matter what it's shorting without even putting a coil in it. ONCE, I finally managed to get the whole base together with no shorts, threw a coil in it and got 2.4 ohms. Then I realized the air flow wheel was stuck open so I tried to get that to close a bit, uh-oh unscrewed the whole air flow assembly from the deck assembly about 1/4 turn. Tightened that back down and made sure to turn just the air flow ring...with virtually NOTHING else to hold on to. Now it's back to short city. There is something seriously wrong with the way the air flow assembly, my deck assembly and my positive pin are put together.
