Inspection: Stator; Inspection: Rectifier - Mitsubishi 6M60-TL Service Manual

Assembly procedure

Inspection: Stator

• Perform the following inspections. If any abnormality is found, re-
place the stator.
(1) Continuity between each lead wire
• Check that there is continuity between each stator lead.
• If there is no continuity, the lead has broken.
(2) Continuity between each lead wires and the core
• Check that there is no continuity between lead wires and the
core.
• If there is continuity, the lead wire has short-circuited.
Inspection: Rectifier
• Check the function of diodes within rectifier properly. If any fault
is found, replace the rectifier.
If resistance is infinite in both cases, the diode has open.
If resistance is close to 0 Ω in both cases, the diode has shorted.
A, B, C, D: Lead connecting area of stator coil
E, G: Heat sink area
F: Regulator connecting area
• Inspection should be conducted twice, changing over the posi-
tive probe and the negative probe of the tester.
CAUTION
• When inspecting using a tester, the current flowing through
the rectifier is smaller than usual. Therefore, an incorrect re-
sistance value may be indicated on the tester.
Additionally, incorrect indications become larger as the
range of the tester gets smaller. Set the tester to the largest
possible scale.
Assembly: Stator
• To install the stater, follow the disassembly sequence in reverse.
