I dropped my bike a few weeks ago and since then, neither of my left signals won't flash. I was parked on a slight incline putting air into my tires. I put the air hose back and the next thing I knew the GS was on the ground. Ever since then the turn signals were acting kind of goofy but now neither the front or rear signals work. The signal indicator still flashes but no lights. I tried checking the wiring and took apart part of the signal control housing. Everything looks normal but then again, I'm no electrical engineer or anything. I guess I could check if the bulbs are burned out but both were working fine earlier which leads me to think it's something else. The right signals work fine. Anyone have any ideas?
