If you have the 9720frm accessory kit, locate the power connector
housing and pins. You will be connecting wires to the pins and
will need to be able to hold the pin steady while soldering. Using an
old-fashioned wooden clothes pin as a vise is a good choice, but try to
find one these days. A pair of needle-nose pliers with a rubber band
around the handle to hold the jaws closed works but too heavy a rubber
band can apply too much pressure and crush the pin.
Proceed with assembly of the power connector as follows:
( ) Prepare the four 16" lengths of stranded insulated wire
supplied with the 9720frm kit by stripping 1/4" of insulation
from one end of each wire only. Twist and tin the exposed
wire strands then clip off the tinned end so that a 1/8" stub
remains.
( ) Solder one of the power connector pins to the end of each
wire. Steady the pin as discussed above and lay the tinned
end of the wire in the "trough" of the pin as shown in the
illustration. Solder the connection by holding the soldering
iron against the wire and pin until the solder remelts. You
should not need to add more solder. Allow the joint to cool
and test it by wiggling the wire to make sure the joint is firm.
Do not wrap the "wings" of the pin around the wire.
( ) Slide the power pins into the connector body. Note the
orientation of the pin as shown in the illustration. Slide
the pin in until the catch on the back of the pin engages
the slot in the connector body and you feel the "snap" as
it locks in place. Give the wire another good tug to test
the solder joint and that the pin is latched in place.
If the wire comes loose, don't panic. The pins can be released from
the connector by using a knife blade or small tool to reach through
the slots in the connector body to press down the catch.
( ) Prepare the free ends of the wires by stripping 1/4" of
insulation from the end and twisting the exposed wire
strands tightly. Do not tin these wires. Push each wire
though the "+", "G", "SG" and "-" holes in the board as
shown in the illustration (note the polarizing tabs on the
connector body) and check to make sure there are no
stray wire strands that did not make it through the hole
before soldering in place. Clip off any excess on the solder
side of the board.
Use the 3 nylon wire ties to group the four wires together by placing
