Subject: Does anybody know where the switches (FETS) for HD voltage are located

Does anybody know where the switches (FETS) for HD voltage are located

Sorry, me again,

we managed to locate the problem, why my HD doesn't start spinning. The
Voltages for the logic and the motor of the HD are present, if the HD is
disonnected. If I connect the HD, voltage is braking down to less than
1V. If we bypass the voltage my JBS 20 works fine! So I think I have to
locate the unit which switches the voltage for the HD (the ON
button???). We already checked the FET at the upper end of the top PCB.
It seems to be OK.

I'll be greatfull for any help.

Cheers Markus
