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. Be sure that all connections are securely snapped.
4. Try replacing the batteries.
5. 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.
Elenco ® is not responsible for parts damaged due to
incorrect wiring.
Basic Troubleshooting
Note: If you suspect you have damaged parts, you can
follow the Advanced Troubleshooting procedure on page 4
to determine which ones need replacing.
Review of How To Use It
(See page 3 of the Projects 1-101 manual for more details.)
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 FOR ALL PROJECTS 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.

WARNING: CHOKING HAZARD -
Small parts.
Not for children under 3 years.
!
Batteries:
• Use only 1.5V AA type, alkaline batteries
(not included).
• Insert batteries with correct polarity.
• Non-rechargeable batteries should not
be recharged. Rechargeable batteries
should only be charged under adult
supervision, and should not be
recharged while in the product.
• Do not mix alkaline, standard (carbon-
zinc), or rechargeable (nickel-cadmium)
batteries.
• Do not mix old and new batteries.
• Remove batteries when they are used up.
• Do not short circuit the battery terminals.
• Never throw batteries in a fire or attempt
to open its outer casing.
• Batteries are harmful if swallowed, so
keep away from small children.
• Do not connect batteries or battery
holders in parallel.
!
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.
Adult Supervision: Because children’s abilities
vary so much, even with age groups, adults should
exercise discretion as to which experiments are
suitable and safe (the instructions should enable
supervising adults to establish the experiment’s
suitability for the child). Make sure your child reads
and follows all of the relevant instructions and
safety procedures, and keeps them at hand for
reference.
This product is intended for use by adults and
children who have attained sufficient maturity to
read and follow directions and warnings.
Never modify your parts, as doing so may disable
important safety features in them, and could put
your child at risk of injury.
