Here is a question from a Yocan UNI Pro user:
I am getting a "Shorted" message. How can I correct this issue?
Unscrew the vape cart a turn or so and it might work. Happens to most of the Yocan UNI Pro short circuit error.
Here is vape experience from @ Badfail:
I guess I'm late to this party but I did recently solve this issue, and the problem isn't a broken device OR a broken cart. The problem is that due to the way carts are manufactured, there can be some variance in extrusion on the center post, and the Uni does not have a spring-loaded center post on the magnetic 510 adapter. Hence, when you press the button and get blinking lights, one of two things is happening:
The cart center post is recessed and not making sufficient contact
The cart center post is extruded and getting pushed in, causing a short
That's why there are multiple working solutions in this thread: switch carts or loosen the adapter. You can tell which of the above is happening by whether or not the outer wall of the adapter is touching the bottom of the cart when you screw it on. In either case, you can usually fix it by adjusting the cart center post with a pair of needle nose pliers. Giving it a slight turn about 2 degrees can resolve a short.
