- 1). Attach the zener diode's positive ended (marked with a plus) to the positive end of your battery by wrapping the flexible wire of the diode around the positive terminal of the battery.
- 2). Optionally, solder the diode's positive wire to the positive terminal of the battery to make the adjustment more permanent.
- 3). Use the electrical tape to secure the wire to the battery (if you didn't solder). Wrap the entire connection in the electrical tape to insulate it. There is now 12 volts between the other end of the zener diode and the negative terminal of your battery.
