Sounds like the 510 pin on the Evic Mini VTC just isn't making connection (if I had to guess). Or the coil isn't seated properly in the Arctic. Do you have any other
devices you can test the Arctic on to narrow down the cause of the problem?
I know the Evic Mini VTC has a bit of a shallow 510 pin, but I'm not sure if it can be wiggled up or adjusted.. Maybe someone with one will chime in.
