8.
Make a Western Union splice between the two red transformer wires and the 4” white FASTON
wire.
i.
Solder the splice.
ii.
Slide the heat shrink tubing evenly over the splice
iii.
Use the tip or the barrel of the iron to shrink the heat shrink tubing.
9.
Make a Western Union splice between the two black transformer wires and the 4” black
FASTON wire.
i.
Solder the splice.
ii.
Slide the heat shrink tubing evenly over the splice
iii.
Use the tip or barrel of the iron to shrink the heat shrink tubing.
Important Note:
Check your Western Union splices for
smoothness. Sharp wire points must not
push into the heat shrink tubing.
If you even suspect that to be the case,
then you must wrap each piece of heat
shrink tubing individually with a layer of
electrical tape.
Figure 2-Western Union splice has diameter less than the insulated wires and no sharp points
Transformer Secondary Side Preparation
The secondary side wiring is always the same, no matter how the primary side is wired. On the
secondary side, the windings are always wired in series.
