I have a 2001 vt750 cd ace. The old blinkers were electrical taped in place by previous owner so I decided to change them. I changed the front and they worked fine for a couple weeks. Last ride around town I noticed my blinker light wasn’t flashing when I turned them on and blinkers were not working. Now I’m ready to install rear blinkers and they won’t blink. They turn on as a constant but no blinking any ideas?
