Amiga 3000 - keyboard no work

Have an A4000 keyboard, and finally got an adapter from amigakit.us that allows me to connect it to the A3000.

This A3000 is a rescue that had some battery damage. It boots though without a keyboard plugged in. Mouse works, so I can run SysInfo and get results.

Sadly, when I first powered it up the A3000 with the keyboard plugged in it would not boot. If I plug it in while the A3000 is booting normally, the computer resets.

Any idea what I can do here?

Edit: The A4000 keyboard is also a rescue so I have no idea if it works.
