Today I picked up 2 replacement coils for my iclear 30 and neither will work... the one that came on it still works but is gross... the new ones will work on other people's iclears (I tested on a friend's) but give a "non" reading on my mvp v2 and tesla... I know both my tank and coils are authentic and came in the same shipment from innokin.... any idea what the issue could be? Do I need to give up and just get a new tank?
