The front corner work lights are not working on one of my tractors. I had a thread earlier about this and I have done more troubleshooting. Here is a link to that thread. https://talk.newagtalk.com/forums/thread-view.asp?tid=958221&posts=1...

I have two MT535B's so I can compare and trade parts.  I exchanged the light switch from the cab side post and it made no difference, the problem stayed with the tractor.  When you press the switch it clicks and the relay clicks but neither the led nor the lights come on.

I have attached two pictures.  One shows the light switch and the lights not working.  The other shows the fuse panel and the yellow arrow is pointing to a terminal that is neither positive nor ground.  I can make it either positive or ground but it doesn't affect the function of the light switch or anything else that I can tell.  Does someone know what it's supposed to be?  Also I do have power to the fuse (both sides have power) with the red circle, which is the fuse that controls those lights on my other tractor.
