My DS won't fire. I checked the batteries on the charger and in other mods and the batteries are fine. I bought all new replacement components from Defiant Designs and replaced every single component in the mod from the button down to the negative contacts. I tested multiple tanks and then tested those tanks on other mods and they are all in good working order as well. I can't for the life of me figure out what is wrong since in theory, the only potential issue should be that contact is not being made somewhere in the circuit or that something is interrupting the circuit and causing a short.
Any ideas?
