Hi,
I'm looking for the schematics to the power distribution box that use to
sit in the bottom of the rack. I have browsed bit-savers.org but I don't
know where too look. Can anybody give me a clue?

Problem for this one is when putting the switch in local mode the big
relay (contactor?) is activated, bit after a white it starts to jumps
between activated/deactivated. I measured the voltage over the coil and
it decreased rapidly when it happens. The contactor is tested standalone.
I have cleaned this up and repainted it, but have no pictures after the
refurbishment.
