Fine grain Sand paper will do wonders to your mods firing everytime!! Cleaning your mod pins with Fine grain sandpaper with solve most problems of not firing/misfiring.......bottom of mod getting real hot.... Sand lightly the pins to get rid of corrosion that form on the pins. This will solve the misfires.....not firing......bottom getting real hot.

Clean to top pin (bottom pin as well) with sharp metal (i use fine sand paper but screwdriver works as well) The top pin is dirty/corroded......power that should be going to the top is going to the bottom.

Anyone still use the cheap chargers that you get for free when you buy a mod? Mine works great!! Hahaha!!! Yea it takes long to charge but its free and it works!! Have three Batteries.... just change them when it outs out of power...... Use saved money on batteries.

And time to time bottom of the Mod will get very hot......And I believe its because the top contact is has corrosion/dirty therefore more power is going to the bottom faster then to the top to fire.

Its most likely due to the pins not making good contact. From my experience when the mods don't fire or misfire time to time.....its always due to the pin/s being dirty.....light film forming of corrosion. Many people use some liquid cleaner to clean the metal ends/pins.....and they do work great. But its really waste of money and not needed. All you need to do is get something sharp....ive used a screwdriver...pins.....anything sharp metal and just scrach/scrap both of the end pins. Use fine Sandpaper works best and most clean. Clean the pins time to time with fine sandpaper when you notice bottom gets hotter then usual or misfires. This should fix ur issue.
