My rear running lights aren't working. The brake light running light, and brake light is lighting up when pressed. Fronts are working fine. I took the covers off to take a look and the rear right light (if your standing behind the bike) had a bare black wire not connected to anything. I assumed that was the problem and it was a ground but when grounded did not solve the problem. Any help would be appreciated. BTW the blinkers do work when pressed Thanks!!
