brake light issue, hot on both wires.
im getting hot on both legs which i assume is not what i want.
brand new bulbs, and cleaned the tail light board, all fuses good.
i disconnected leads going to the break switch which are also both hot.
any suggestions here would be appreciated

While I'm sure it would help to know the model, year, stock or AM, etc. I'll take a stab at it. While not knowing the details of your brake light circuit, generally to have hot applied to one side and when you want the light to come on, you pass a ground to the other side. When the ground is not applied, you will feel the hot on both sides. My guess is that whatever is responsible for passing the ground to light up the brake filament is not doing it's job.
Then again, I could be way off base, I've been away from electrical/electronic stuff for a looooooooooong time......
YMMV

Usually when something goes awry after I have been working on my bikes, it is something I did, touched, or bumped when I was working on the bike...
I'm not an electrical expert, but have found through the years that hot wires can be caused by resistance from dirty/incomplete connections, or a draw that is more than the wire gauge can handle...
My guess is that when you cleaned that tail light board, you damaged a circuit, bent a pin in one of the plugs, etc... That is now causing the issues....
Hopefully, those much smarter than myself.... may know exactly where to look....

If you haven't don't anything to the bike that may have caused this ... first thing I would do is check all the electrical connections in that circuit (starting at the fuse block) for corrosion. Pull each fuse from the fuse block replace them, spray a penetrating oil in the fuse block and blast with air. Penetrating oil seems work better than contact cleaner but will require some cleanup. You will be amazed at the problems corrosion can cause on your electrical system.
