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, and
replace it if it is damaged (this kit includes a spare). To
replace, pry the broken one off the motor shaft using a
screwdriver, then push the new one on.
6. If a fiber optics circuit isn’t working, make sure the clear &
black cable holders are pushed all the way onto the
LED/phototransistor, and the fiber optic cable is pushed into
the holders as far as it will go. The cable should be standing
straight up in the holders.
7. If the flexible sheet in the sound energy demo container is
damaged, replace it with a spare (if one was included), or use
household plastic wrap.
8. If the echo IC (U28) stops working, turn the circuit off and on
to reset it.
