Yamaha CS80

Apologies for bringing this up again, but I've just come back to my
CS60 after a bit of an absence.

So, the CS60 appears to be stuck in sustain II mode, no matter which
way the switch is switched. Does anybody know which pins on the switch
I should be checking with a multimeter to try and trace the problem?
Is there any safe way I could "short circuit" it into sustain I mode?
(If it's going to be stuck, I'd rather have it stuck in sustain I
mode)

Also, does anybody know any CS techs in Berlin? I've already talked to
the guy at Xtended but he's not too keen to take on any Yamaha CS work
unfortunately.
