Advanced Troubleshooting
(Adult supervision recommended)
ELENCO ® is not responsible for parts
damaged due to incorrect wiring.
If you suspect you have damaged parts,
you can follow this procedure to
systematically determine which ones need
replacing:
1. 4.5V lamps (L4), motor (M1), and battery
holder (B3):
Place batteries in holder.
Place the 4.5V lamp directly across the
battery holder, it should light. Do the same
with the motor (motor + to battery +), it
should spin to the right at high speed (use
two 1-snap wires as spacers). If none work
then replace your batteries and repeat, if still
bad then the battery holder is damaged.
2. Set the motor (M1) by itself and place the
fan on it. If the Motor (M1) does not
balance the fan evenly: Inspect the black
plastic piece at the top of the motor shaft, it
should have 3 prongs. If missing or broken,
replace it with the spare that is included with
this kit (a broken one can be removed with
a screwdriver). If the motor is fine, then
inspect the fan.
3. Jumper wires: Use this mini-circuit to test
each jumper wire, the lamp should light.
4. Snap wires: Use this mini-circuit to test
each of the snap wires, one at a time. The
lamp should light.
5. Slide switch (S5): Build project 10. With
the switch in the left position (C), the left
lamp should be on. With the switch in the
right position (B), the right lamp should be
on.
6. Press switch (S2): Build project 75. When
you press the switch, the lamp should light.
7. Meter (M5): Build project 75, but replace
the 3-snap wire with the meter.
a. Set the meter to the 5V scale and push
the press switch. The meter should
read at least 2.5V.
b. Set the meter to the 1mA scale and
push the switch. The reading should be
over maximum.
c. Set the meter to the 1A scale and push
the switch. The meter should show a
small current.
8. Electromagnet (M3): Build project 46 and
place the iron core rod in the electromagnet.
When you press the switch (S2), the rod in
the electromagnet should act like a magnet.
9. Iron filings: Sometimes the filings may
stick to the case, making it appear cloudy.
Move a magnet (the one in this kit or a
stronger one in your home) across the case
to clean them off.
10. Compass and magnet: The red
compass needle should point north,
unless it is near a magnet or large iron
object. The red compass needle will point
toward the black (S) side of the magnet.
