I have tail lights working but no light when i brake, third light is out as well. Bulbs are fine............

possibly the brake light switch gone bad/loose??

It's on the pedal assembly.

Checked the switch, read the book making not a lot of sense. seems like it the plunger or what ever it is should be out when brakes are not on an in when its being depressed??? mine is the opposite

There's a rubber pad that pushes the switch only when the brakes are not being pressed. This way even a very slight brake pressure will turn them on. If it were the other way the switch mechanism needed to counteract varying brake pressure would be overly complex. The switch probably grounds when it's "plunger" is out. Test it to see.

 

Could also be something with the wireing. The brake lights run off the same circuit as the choke, so if the choke power wire grounds out it will blow the fuse. You have checked the fuses I take it?

Fuses are good
