“Check the Continuity First, check that you don’t have a short circuit between the positive and negative columns. To do this, use the continuity function on your multimeter. A continuity test checks for a direct connection between two points in a circuit. The symbol for the continuity tester usually looks like the one shown here. You don’t want a direct connection between the positive and negative columns because that would short-circuit the battery and stop the game from working. Use the continuity tester to check for short circuits. Turn the dial on your multimeter so that it points toward the continuity symbol. Plug the black measurement lead into the multimeter’s COM socket, and plug the red measurement lead into the multimeter’s V socket. Touch the tip of the black and red measurement leads to each other, and you should hear a beep to indicate that there’s a direct connection.”
