Hopefully this is allowed, I noticed most the threads are locked guessing because it's an older device now. I've had it since preorder and the last week or so it keeps throwing up the errors no coil detected, ohms too high and short detected in no particular order. I get lucky and it'll work longer than 2 seconds before it shuts down with the errors every so often. I took the back off and checked the 510 nut and it's tight, can't get it any tighter. I've tried 3 different rdas I have and it does the same thing with all of them even with fresh builds. They all work on my vt75 just fine. I'm not sure what else to try at this point and I'm 2 seconds from throwing it in the trash. Anyone have any ideas?
