Ok, I'm no electrical wiz. I have an old computer that wants 220. First
of all, I got this computer without the 3-prong plug (it'd been cut off).
Without paying attention to the "220" which was written on the transformer
inside, I wired a plug onto the power cord and plugged it in. Needless to
say the unit didn't come on, but I'm hoping that it didn't mess anything
up. I wouldn't think it did.
Anyway, what can I do to run this thing off of 110? The transformer has a
solid black lead going to the black wire of the power cord (through the
switch), a black lead with a white stripe looped back into the xformer via
a white lead, and a blue lead with a white stripe connected to the red
wire of the power cord (through the switch with an inline fuse...the fuse
is fine).
The side connected to the cpmputer board has a rainbow of seven colored
wires in the order (from left to right): brown, red, orange, yellow,
green, blue, violet.
1547 is stamped on the transformer. ?.
I'd like to make this run off 110 without having to modify the actual unit
itself.

Sam:
You are in luck. From your description of the wires available ----
(Check with an Ohm meter for continuity to be sure.) The White, and
Black wires _should_ be the ends of 'ONE of TWO' 110v windings.
(1) After making sure that they are the ends of the same winding, apply
110v.
(2) Add the Black w/White stripe to the Black connection, and _carefully
measure the voltage between the White, and Blue w/White stripe. It will
be either '0', or '220' volts.
(3) IF it is zero, then that wire (Blue w/White stripe) hooks to the
same place as the White wire,
(3a) If the voltage is '220', then the Black w/White stripe goes with
the White wire, and the Blue w/White stripe goes with the White wire.
