During the manufacturing process, there can be some tolerance in extrusion on the center pin, and the UNI Mod does not have a spring-loaded center pin on the magnetic 510 adapters. So, when you press the fire button and get blinking lights, one of two things is happening:
* The cartridge center pin is recessed and not making sufficient contact, the UNI mod can’t load the cartridge correctly, and flash 5 times.
* The cartridge center pin is extruded and getting pushed in, causing a short, the UNI mod flash 3 times.
So, there are two ways to fix UNI Mod flash issues: switch cartridge or loosen the adapter.
Switch cartridge
The mod is less likely to break than the cartridge.
And the atomizer shorts are caused by the atomizer – the coil in the cartridge is broken.
Loosen the adapter
You can usually fix it by adjusting the cartridge center pin with a pair of needle-nose pliers. Giving it a slight turn about 2 or more degrees can resolve a short.
