This is to all that helped or was in the process of helping. I couldn't get my headlights to work on my B7100-D and received some excellent points to check and wiring diagram. I had said it was probably something simple and it was. Looking at the wiring diagram the headlights grounded to the hood. The hood is grounded to the tractor frame. I had the hood just laying in position to hook up new lights and wiring and not bolted to the frame. Put the hood back and as God said "let there be light and there was light and He saw it was good". How true it is, great to have lights. Thanks to all for the help and it is appreciated. I am so happy I found this site and have all the experience from you all to keep me up on my first "old" tractor.
