1. Most circuit problems are due to
incorrect assembly. Always double-
check that your circuit exactly matches
the drawing for it.
2. Be sure that parts with positive/negative
markings are positioned as per the
drawing.
3. Sometimes the light bulbs come loose,
tighten them as needed. Use care since
glass bulbs can shatter.
4. Be sure that all connections are securely
snapped.
5. Try replacing the batteries.
6. If the motor spins but does not balance
the fan, check the black plastic piece with
three prongs on the motor shaft. Be sure
that it is at the top of the shaft.

Basic Troubleshooting
Note: If you suspect you have damaged
parts, you can follow the Advanced
Troubleshooting procedure on page 5 to
determine which ones need replacing.
Review of How To Use It
(See p.3 of the Projects 1-101 manual for more details.)
WARNING:• Always check your wiring before turning
on a circuit. Never leave a circuit unattended while
the batteries are installed. Never connect additional
batteries or any other power sources to your
circuits. Discard any cracked or broken parts.
The Snap Circuits
®
kit uses building blocks with snaps to
build the different electrical and electronic circuits in the
projects. These blocks are in different colors and have
numbers on them so that you can easily identify them. The
circuit you will build is shown in color and with numbers,
identifying the blocks that you will use and snap together
to form a circuit.
Next to each part in every circuit drawing is a small number
in black. This tells you which level the component is placed
at. Place all parts on level 1 first, then all of the parts on
level 2, then all of the parts on level 3, etc.
A large clear plastic base grid is included with this kit to
help keep the circuit block together. The base has rows
labeled A-G and columns labeled 1-10.
Install two (2) “AA” batteries (not included) in the battery
holder (B1). The 2.5V and 6V bulbs come packaged
separate from their sockets. Install the 2.5V bulb in the L1
lamp socket, and the 6V bulb in the L2 lamp socket.
Place the fan on the motor (M1) whenever that part is
used, unless the project you are building says not to use it.
Some circuits use the red and black jumper wires to make
unusual connections. Just clip them to the metal snaps or
as indicated.
Note: While building the projects, be careful not to accidentally make
a direct connection across the battery holder (a “short circuit”), as this
may damage and/or quickly drain the batteries.
WARNING: SHOCK HAZARD - Never
connect Snap Circuits
®
to the electrical
outlets in your home in any way!
WARNING TO ALL PARTS WITH A SYMBOL - Moving parts. Do not touch the motor or fan during operation.
Do not lean over the motor. Do not launch the fan at people, animals, or objects. Eye protection is recommended.
