It has five rows and 17 column.

After the columns and rows are soldered together then it's time to connect the key switches. To do this you must place a diode over each pin on the key switch and solder it. This will shield the pins from current and prevent them from being shorted. The diode allows current to only flow in one direction. It has a visual indicator, a black band, that indicates which direction current will flow.

Jump-starting the battery

Most people keep a few sets of jumper cables in their trunk in case of emergency however, jumping a battery on modern automobiles might not be the best idea. These vehicles are equipped with numerous digital and computers that communicate with one another. A voltage surge when the battery is connected to another battery could damage the components, rendering your car undriveable.

Connect the cables to the vehicle operating. Let it run for two minutes. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it).
