I just change out my battery and fuses but my headlights and turn signals are not working. I have power to my fuse block and the switches are connected but still no lights they were working.
before you get too involved - you need to know that its a common issue for that round light switch to have water in it preventing it from working right and can rust. Just make it easy on yourself and replace that switch in the dash.
Have you checked continuity through the switches? These switches are problematic. I own a BX23 and have had multiple issues with the switches. Three times in nearly 500 hours, I have had to take the switches apart and clean out the water and corrosion.
