Measurement of
coil resistance
* For the setting method of the tester, see Basic Course:
II-1-c.
¡ Remove the unit of electronic circuit and measure the
coil resistance.
<Tester range: R x 10Ω>
<The tester lead pins have no polarity>
Coil units (1), (3)
• 1.0 ~ 1.5kΩ
→ Good
• Out of range of 1.0 ~ 1.5kΩ
→ Replace coil unit.
Coil units (2)
• 1.9 ~ 2.3kΩ
→ Good
• Out of range of 1.9 ~ 2.3kΩ
→ Replace coil unit.
Check of train
wheel
* Refer to Basic Course: II-2-b.
Check of solar
cell side
mechanism
* Refer to Basic Course: II-2-c.
Check of solar
cell
¡ Check the solar cell for breakage and stain, and check
its electrode for stain and flaking.
Breakage of solar cell
→ Replace solar cell.
Stain
→ Remove stain.
Flaking of electrode
→ Replace solar cell.
