So out of nowhere my vape ( itaste vv v3 & trident v1) stops firing and the led is staying green for 6 seconds indicating a short. I tried rebuilding the coil, no luck. Reads 0 ohms. Then I tried pulling up the center pin on itaste and pulling down contact on trident. No luck. I then tried to rebuild 2 different coils and still no luck, 0 ohms. I tried my protank and it reads non. Then I tried my buddy's clearimizer on my itaste and it worked fine. What is going on here?
