■ Measure the resistance of field coil with a circuit
tester.
■ NORMAL RESISTANCE
[Remedy]
If the resistance is not normal, replace rotor with a new one.
(2) CHECKING OF DIODES AND RESISTORS ON THE ROTOR
■ Unsolder and take out the diodes and a resistor from rotor.
■ Measure the resistance of diodes.
\
Each rotor has three diodes. Check the resistance of each diode.
■ Measure the resistance of surge absorber connected to the diode holder.
■ Check the magnetic force of permanent magnets molded in the rotor.
[Remedy]
(1) If the magnetic force of rotor magnets is weak, or if the surge absorber is not good, replace the rotor
with a new one.
(2) If the diode is not good, replace it with a new one.
CAUTION: In case the diode troubles are frequent, check the surge absorber because it
might be broken even if its resistance is normal (
∞ Ω). In such a case, replace the
rotor with a new one.
