Disassembly: Field Coil; Disassembly: Stator; Inspection: Field Coil - Mitsubishi 6M60-TL Service Manual

#940 ALTERNATOR
Inspection procedure
54-32

Disassembly: Field coil

• Remove screw A (2 places).
CAUTION
• If screws B are removed first, the weight of field coil may be
placed on the joining portion with regulator which is fixed
with screw A, causing break of the joining portion. To avoid
this, remove screw A first.
• Remove screw B (3 places).
CAUTION
• If screw B are removed, the field coil will fall under its own
weight. Keep the field coil supported with your hand.
• Remove field coil.
CAUTION
• Do not remove the field coil forcibly. Otherwise the portion
that joins with the regulator may be caught by the stator
coil.

Disassembly: Stator

• Disconnect lead of stator from rectifier. The lead is soldered to
the diode of the rectifier at 4 places.
CAUTION
• Unsolder within as short a time period as possible (within 5
seconds), otherwise diode can be easily damaged by heat.

Inspection: Field coil

• Measure the resistance between the terminals of field coil.
• If the measured value deviates from the standard value, replace
field coil.
