! Mark the left-hand coil wire at 5” from where it exits the coil.

! At the 5” point, remove 1” of insulation from the wire.

! Form the area stripped of insulation into a through-connection half loop.

! Loosen the Fahnstock clip mounting screw for the EAR2 clip.

! Pass the through-connection between the EAR2 clip and breadboard, with

loop going around the Phillips screw shank, as shown above.

! Tighten the mounting screw for the EAR2 clip until snug.

! Measure the wire exiting from the EAR2 connection, and at the 5.5” point

remove 1” of insulation from the wire.

! Form the area of wire stripped of insulation into a second through-

connection half loop.

! Loosen the Phillips screw that mounts the Fahnstock clip used for the GND

connection.

! Pass the through-connection between the GND clip and breadboard, with

the loop going around the Phillips screw shank, as shown above.

this wire until instructed to do so!
