Issue with Aspire Nautilus 5ml Tank Pin or what?

[vmshaw]

Hi y'all,
I am hoping to get some answers that I have to my Nautilus tanks and coils. I have been vaping this set-up for probably 10 years. Recently I am having issues with the tank or coils not connecting or firing correctly. I have cleaned the pin carefully with alcohol and Qtip, soaked the bottom in alcohol. I bought new mods, new coils. I vape BVC 1.8. When I hit it, it just either does nothing really like pssss, then wait a few seconds it will fire fine. On one device I had only about 2 weeks it would say "no Atomizer". I never had this issue before, I thought maybe I am getting the mini coils...but they are the same

Any help or advice would be appreciated.
Thank you!

Original nautilus has a spring attached to the 510 pin. If it is missing, you won't make a connection. The spring will corrode after time and possibly lose tensile strength.
