Now you will see the transformer, the fuse holder and the
power jack. There are four wires leading from the transformer
to a plug which connects to the PCB. The remaining three
wires belong to the input of the transformer; one of them
should be soldered to the power jack, one to the fuse holder
and one unconnected.
If you have an ohmmeter, proceed as follows: Move the power
switch to the ON position (the drive should stay unplugged)
and measure the resistance between the two outer pins of the
power jack and write it down. Then measure the resistance be-
tween the unconnected wire and each of the other two wires
(one going to fuse holder, the other to power jack). When the
measured resistance is slightly above the value you wrote
down, you have found the wire which has to be unsoldered and
where you have to solder the yet unconnected wire. If the re-
sistance is way below the value you wrote down, you found the
wire which you should not touch :-)
If you have no access to an ohmmeter, unsolder the red wire
connected to the fuse holder and solder the black wire to
it instead. It is very likely that this is correct (at least
this applies to all my floppy drives), if it is not, replace
the fuse you have blown, resolder the old wire to the fuse
holder and replace the wire you did not touch yet with the
unconnected one.
