The other day I left it out in the rain (04 super glide). The next day I pulled it out of the garage and the left signal wouldn't work. Now it keeps turning on by itself while riding, but it won't work when when I want it to. Any ideas? I took the left switch assy apart and let it hang by the wires to dry out during my work shift and cleaned up the contacts that ground on the handlebars....no help.

 

having the same issue on an 07 streetbob. soon as i key on left turn is on.

 

Not sure how to let members know that this thread isn't an issue anymore. I tore the switch assy apart and let it air dry during a 4hr shift at work and cleaned up the contacts that ground on the handlebars. The symptoms continued but lessoned each day I rode it. Seems fine now. Something musta got wet while parked in the rain and dryer out with time. Thanx
