Elevator is on top floor, with constant brake switch fault.

Is there a way to get around it to drive it down on inspection?

For those wondering, it's a MRL...
We raised the counterweight with a chain Block attached to brackets above

Found the brake power bridge rectifier was faulty (fused) , blowing the F1 fuse.

Replaced the rectifier and fuse, good to go.
