Malibu lighting is as cheaply built as possible but works.
The power supply is fully functioning from the output to the timer but the output terminals as described are damaged. Not just rusted but completely broken loose and unconnectable.
I had to disassemble it and hot glue a post, then connect a lead and hot glue it in place. It’s working fine and replaced my old one and is higher power so I’m hopeful it will give me the service my original did.
