Brake light stays on all the time as if brakes are applied,2001 harley classic

See if you have free play on your front brake lever, if you do push the lever forward and see if the light goes out. If it does, put a rebuild kit in your master cylinder, the spring is weak. next, check the bulb, vibration can make the two filaments touch.

Sounds to me like you have your brake wire crossed with a constant somewhere... follow the wire from the brake as far back as you can to see where it may be crossed (if anything it will rule that out)
