Hi, I have an issue with my mod which is a UD Balrog 7.0, for sometime now my mod has been showing "Shorted" whenever i press the fire button, then I later discovered that whenever i press down on my battery w/o the battery cover, it works just fine, but when i release my hand on the battery, it just goes back to the screen showing "Shorted". My Atomizer is a Psywar Blade RDA. Any idea why this happens? if so, let me know, with solutions, thank you, and also, i've been trying coils after coils, and different atomizers, but it still keeps showing "Shorted" other than that, the pressing down on the battery works.
