twilight sentinel stop working so I turned it off.
all my outside lights come on when i start the car day or night, and turn off when i turn the key off. turned twilight sentinel back on and the same thing happens. would that be the headlight switch in the dash or the sensor on top of the dash ?

Just so I am clear, the lights stay on when this switch is on or off? So the head lights stay on when the key is on no matter the position of the headlamp switch? Take a look at this info and let me know what you think.

Maybe I am not understanding the issue but this explains the operation of this system so let me know what position you have each switch in and that will help determine what the issue is.
