The left front turn signal bulb is on continuously when the bike is running, and remains on when the ignition is switched off. The bulb does not flash at all. The left rear bulb flashes at a rate faster than normal. The turn signal indicator on the dash flashes at a faster rate as well. The right front and rear signals work and flash normally at the normal rate. Currently I have to remove the left front bulb to keep from discharging the battery. I have opened the turn signal switch. It looked fine. Lubed it with dielectric grease, and reassemble. Still no solution. I think a may have a short/fault. Please advise.
