So I was changing out the battery in my muff for the first time and when I put my new battery in the battery connecter stopped working entirely. My 9v was a little big so I had to shove it in a little bit. I closed the back and plugged in and it didn’t work. I tried putting the original battery back in and it didn’t work either. The only way it gets power is through plugging in an adapter.

Any help or advice would be hugely appreciated 🙂
