If there is no voltage at the output, check the corresponding
fuse (see table above). If the fuse is blown replace it and
make certain that there is no short-circuit in the output
connector, the cable or the bath.
If there are no blown fuses, check the input voltage at the terminals of the
circuit board corresponding to each bath (see table above).
