Thanks all.
Had a spare arvo and I pulled Rudy out of the game.
It was 1 x wire snapped off one of the small coils.
For those of you that havent seen this little guy in 'frankenstein mode' here he is ....
While I was in there I re-soldered all the other wires as some were 'just' hangin on, so I made em all nice and rock solid.
Also took the gears apart and cleaned em with wax/grease reomver & a toothbrush.
I also checked the 2 nylon connectors in this Rudy head and they are perfect, one is brand spankin new
All perfect again now - eyes now close and move left/right.
Thanks again to all that replied
