Pioneer Pl-300 auto return not working

Hello everyone,

I got a Pioneer Pl-300 for fairly cheap. Ive yet to plug it into an amplifier but everything looks in order.

Except the auto return function doesnt kick in at the end of record. The ´Cut’ button is working fine with the arm then returning. But I know it should be doing it automatically at the end of the record as well.

Any advice or tutorial on how to try and fix this?

Thank you
