Section 4: Wiring it All Together
Get out your trusty soup bowl and empty the contents of the “Top Level Hardware”
envelope into it. The “GT-102 Wiring Kit
7
” is packed in the chassis. It’s the source of all
the wire used in this section. Remove the 11 small black Phillips-head screws that hold
the cover in place to retrieve the wiring kit.
The kit has three kinds of black single conductor wire:
1.
18 AWG stranded (thickest wire, about 24”
supplied)
2.
18 AWG solid, a 6” piece, the insulation of which
is used in preparing the shielded cable ground
wires)
3.
22 AWG stranded (thinnest wire)
If you compare the black wires side by side, it will become
quickly apparent which is which.

Attach the Power Supply Ground Wire
1.
Cut a 7” length of black 18 AWG stranded wire. Strip 1/4” of insulation from
both ends of the wire.
2.
Insert one end of the wire into the GND eyelet (this is different from the PGND
eyelets!) of the power supply PCB. Insert it from the solder side and solder it on
the component side.
3.
Tin the other end of the wire and insert it into the eyelet of a #6 lug. Crimp the
wire and solder it to the lug.

Note: The X1, X2, VCC, PGND1 and PGND2 eyelets will remain open until a later
assembly step.

The overall mechanical parts of the GT-102 and GT-108 are quite similar, so the wiring kit may say either
GT-102 or GT-108.
