If the trailer is attached one possibiliy is that the total amp draw exceeds the fuse, which can be corrected with LEDs. But first measue the amp draw on the brake and charge wire. Have you checked for the correct fuse size? Is the trailer battery good and how do you know?

No, the trailer is not attached...
it is 30 amps fuse, which is correct size.
no sure what you meant by "trailer battery"..
