Connection the Wires
We will connect all of the electronic parts by connecting their wires with screw on
wire connectors. Some of the connections will be between two wires, and some of the
connections will be between three wires. Once all of the wires are connected, screw
the top on, attach the rubber feet, and label the ‘On-Off-On’ switch and you are
finished with this part of the etcher. (By the way, when the ‘On-Off-On’ switch is in
the top position, the unit will be passing AC current. When it’s in the bottom
position, the unit will be passing DC current.)
Most of the connections on the electronic parts will be labeled with a number or
something, but it was a little confusing to me which connection to use when it came to
the transformer and the bridge rectifier. Because of that I’ve drawn a little diagram
and numbered the wires for easier identification. We are looking at the bride rectifier
from the perspective of the flat side down and the pins sticking up.
Instructions for connecting the wires 1) Connect the following three wires using a twist on wire connector: a.   The green wire from the power cord (this is the ground wire) b.   The transformer wire #2 (see transformer diagram) c.   The transformer wire G that was connected to the transformer’s little tab (see transformer diagram) 2) Connect the following two wires using a twist on wire connector: a.   The black wire from the power cord b.   The end wire on the fuse holder 3) Connect the following two wires using a twist on wire connector: a.   The middle wire on the fuse holder b.   Wire #1 on the ‘On-Off’ switch 4) Connect the following three wires using a twist on wire connector: a.   Wire #4 on the ‘On-Off’ switch b.   Either one of the lamp wires c.   The transformer wire #4 (see transformer diagram) 5) Connect the following three wires using a twist on wire connector: a.   The other lamp wire b.   The transformer wire #5 (see transformer diagram) c.   The white wire from the power cord 6) Connect the following two wires using a twist on wire connector: a.   The red banana jack wire b.   Wire #2 on the ‘On-Off-On’ switch (DPDT) 7) Connect the following two wires using a twist on wire connector: a.   The black banana jack wire b.   Wire #5 on the ‘On-Off-On’ switch (DPDT) 8) Connect the following two wires using a twist on wire connector: a.   Wire #1 on the ‘On-Off-On’ switch (DPDT) b.   Wire #3 on the bridge rectifier (see bridge rectifier diagram) 9) Connect the following two wires using a twist on wire connector: a.   Wire #4 on the ‘On-Off-On’ switch (DPDT) b.   Wire #2 on the bridge rectifier (see bridge rectifier diagram) 10) Connect the following three wires using a twist on wire connector: a.   Wire #3 on the ‘On-Off-On’ switch (DPDT) b.   Wire #1 on the bridge rectifier (see bridge rectifier diagram) c.   Wire #1 on the transformer (see transformer diagram) 11) Connect the following three wires using a twist on wire connector: a.   Wire #6 on the ‘On-Off-On’ switch (DPDT) b.   Wire #4 on the bridge rectifier (see bridge rectifier diagram) c.   Wire #3 on the transformer (see transformer diagram)
