Installed new turn signals on my 93 Vulcan 750. Bulbs are good. Right turn signal operates normally, the left blinks fast. swapped wires on front signals, got fast flashing on right, so i know it's not the lights. The hazard lights blink fine in rear, alternate flashing on front signals, thats weird! Tried a different turn signal relay, NO CHANGE!! Now I'm stumped!! What else could it be??
