Well, fixed another bus last night. Had a turn signal out of an International. Googled it. Found out the replacement was $139!!! Holy HELL!!!
Managed to get it apart and tracked the issue down to a 1N4007 Diode...which cost about $.11 on average. What a crock!!!
Found an old diode out of my lab kit from college, did a little remove and replace with some solder, and wolla...good as new...except you can see where I pried it apart around the edges.
Hey, Scott, when you have these lights that don't work, save them for me will ya.
