LED Lamp Steps 15-17

STEP 15 - Using a 3" piece of bare 12 or 14 gauge copper wire we are going to attach the two NiCd batteries. First using a fine sandpaper clean off both the positive and negative battery contacts and clean the ends of the copper wire. Using a 20watt soldering iron do not apply the iron to the batteries for more than 3 to 5 seconds

STEP 16 - Tin both the battery contacts and the wire ends as shown then bend the wire into a half circle and solder to the positive terminal of one battery and the negative terminal of the other. Let the solder harden and then twist the batteries into alignment.

STEP 17 - Add a positive and negative lead to the two batteries as shown. Place the batteries into position and tack with silicone. Solder the positive battery lead to the center lead on the switch, solder the lead from the resistor to the last lead on the switch and protect all the connections with shrink tube.
