A First Time Posters Turn Signal Issue!

[TNRider]

Hey crew,

I purchased by first bike (GZ250, duh) an 07, about 4 months ago, and want to start by saying I have gleaned some great knowledge from this site.

Now on to my issue. My turn signal indicator bulb burned out shortly after purchase, so I decided to rig up the dual led light that flashes one bulb for left and the other for right (looked for the instructional video, but did not find it). That worked for a bit, but my soldering was not great, so I just decided to replace the bulb after some flaky performance. I replaced it with a 161LL. Now my left turn signal works every time, while my right works intermittently. Sometimes it will flash and cancel upon start up no problem, other times it will burn brightly upon start up (front and back right turn signals) with no flashing, just a steady bright light. I took the signal bulb cover off and both filaments on the bulb are burning. This will sometimes go away after a few minutes of riding. I replaced the neutral indicator bulb with the same type, just to see of that made a difference (nope).

After reading similar threads it seems that I should clean my turn signal switch. I took out the two screws and the bottom is currently hanging from the handlebars. One of the screws in the back of the switch box is corroded, but I am not seeing any wires and am hesitant about taking anything else apart. What exactly am I supposed to clean, and how do I get to it?

Any help is greatly appreciated!
