Here is a Yocan fan's question:
Just bought my battery 2 weeks ago from a local smoke shop here in Chicago. It’s a YoCan Uni Pro. The led screen now reads “Shorted” Any recommendations on how to fix this? I still have the paperwork and the box and receipt.
First of all, please check the vape cartridge OK or not.
If you have another brand new 510 thread vape cartridge, please install this new one.
And you also can use a q-tip with isopropyl alcohol to clean the contact points of the adapter and battery.
If still can't fix this shorted circuit error, please comment below or contact Yocan support team at email@example.com
