Thanks guys.
For what ever reason with the ithaka it seems like i have to gently lift while putting on the provari otherwise the adjustable pin goes to far up and doesn't make solid contact.
For the penelope I am not sure how the positive nut would have loosened, something was going on I just did a quick rebuild and all is good again in penelope land.
I was wondering to. There for awhile I would clean the contacts on the provari and all 510 threads of the atomizers on a weekly basis. I got lazy and had only cleaned the contact points on the provari. I did clean the threading on all devices yesterday, and there was buildup on the threading of the atomizers. Could that lead to issues?
I don't think dirty threads would jack with your resistance but it will reduce battery life for sure. Maybe it just jacks with Provari's readings.
I know my Provari would act weird when it needed a cleaning.
