Ok I have a 1991 Vulcan 750, and the rear blinkers were a mess when I bought the bike used, but they worked fine. I ended up replacing my rear blinker lights with some LED blinkers, (without changing the original flasher in the bike) since they had started to fall apart. The LEDs worked fine for about a week or two no problems, then the flasher stopped working, I look to see whats wrong and it's melted, obviously the LEDs must have gotten to it. So I buy some OEM blinkers to replace the LEDs and got a new electronic flasher, and yet the flasher still isn't working, so I tried getting an old original flasher used for the same exact bike, and still the flasher dosn't work. I got the volt meter out and there does seem to be a full 12v of power still running to the flasher. My two running lights up front still work, the flasher seems to be the only thing not working.
