4. All wires lead to the switch
In this part we will be connecting all the wires necessary to go to the switch. This will involve first bundling the wires together, soldering them, then positioning them in line with the switch, and soldering it. This part will require some patience and trial and error, as some of these steps can be tedious. Let’s go!
Prepare the voltage regulators by bringing them near the enclosure.
Add tape to all the black wires to keep the ends in place.
The next step will be to solder the ends of the black wires together — but, oops, some solder dripped into the enclosure. That was unexpected! The point of this step is to show that sometimes not everything goes to plan, but this is okay because we can be flexible to fix it and work around it.
Alright. Now with the solder blob cleaned up, moving along.
Solder the ends of the black wires together. Ensure the connection is holding all of the wires.
Position the third hand tool to hold the black wires in place with the gold terminal of the switch.
Now, solder the wires to the gold terminal of the switch. Be sure to check that the connection is secure (once it has cooled).
Bundle the two input wires from the two voltage regulators, and apply tape.
Solder the ends of the two red wires together. Ensure the connection is secure.
Position the third hand tool to hold the red wires in place with the middle terminal of the switch.
Now, solder the red wires to the switch. Ensure the connection to both wires and the switch is secure, once the wires have cooled.
This is what the two solder joints should look like so far.
Take the input wire from the battery connector, and using the third hand tool, position it so that it is near the last terminal of the switch.
Now, solder the connection to the switch.
Here is what all three connections should look like. Ensure that they are secure.
