TROUBLESHOOTING GUIDE
• Check your wiring against the Wiring Diagram and the schematic, very carefully. Be sure all your wires and components
are securely in place in the correct hole and not loose. Make sure the metal in the wires and components is not
contacting any other metal, since this will create “short circuits”. Nearly all problems are due to wiring errors.
• Remember that the battery and electrolytic capacitors have “+” and “–” terminal markings, and be sure to correctly
position the transistors, LEDs, diode, and transformer as per the guides.
• Be sure you have a good 9V battery. If not sure then try a new battery.
• Be sure you understand how to read the resistor color code, so that you use the right value parts.
• Be sure you understand which breadboard holes are connected to which.
