Today I replaced the stock wick and coil with #400 ss mesh and 32g kanthal with 4/5 wraps coming out to about 2.1 2.3 ohms. I got all the coils to fire evenly but while I was dry burning(firing for 2-5 seconds) at a time, I noticed my spinner battery and my Ego twist heating up very hot near the button/threading. Usually if I have a short it will just cut off and go into protection mode, what do you think is the problem?
