Left Rear Turn Signal comes on when key turned on

Hey There,

This is probably an easy one for some of you experienced guys but I am pretty new to the whole wrenching thing. My wife dropped the bike when she was out the other day and wiped out the left front turn signal. I put a new bulb and lens cover on and it works fine. The right front works fine and the right rear works fine. However, the left, rear, tail light is on all the time except when blinking. It should be off like the right one is but stays on. I swapped light bulbs around but that doesn't seem to affect anything.

The front left signal indicator remains on as well.

I am guessing this is some sort of electrical short or something but don't really know where to start looking. I've taken the seat off and checked the connections there and they all seem to be seated properly.

Any suggestions?

I would probably look around in the headlight bucket for wires that aren't covered or may be touching others.

The fronts do have running lights so is there any chance you played with any of the wires?

No, I didn't play with any of the wires up front. I did hook up a sissy bar that has lights on it and it is doing the same thing. I'm wondering if it might have something to do with the turn signal switch itself. If I get it just right, just a hair to the left of center, it will shut off the rear running light and the left turn signal indicator and not turn on the turn signal. Too far and the flasher starts to go, too little and the running light comes on.

There is a "metal "stalk" for the rear turn indicator which the wires run thru to the lamp. The outer part of this is insulated from the inner by a rubber insulator. When the bike fell over the stalk may have been moved enough to short the outer to the inner which could cause this problem. I have had same problem with my CX500,
