So i've had my z125 for over 2 weeks now and today when i was riding my z, it just died out of nowhere and i almost crashed. the bike wouldn't start back up. Some buzzing sound came from behind the bike so i popped the seat open and found that this happened. Turns out the installer at the dealership installed the wires to the side of the battery instead of the front of the battery and the positive side was touching the frame. Battery was hot and puffed.
