17-38 ELECTRICAL SYSTEM
Alternator
Rectifier Inspection
•
Set the hand tester to the 1 kΩ range.
•
Zero the hand tester, and connect it to each terminal to
check the resistance in both directions.
○
The resistance should be low in one direction and more
than ten times as much in the other direction. If the rec-
tifier [A] shows low or high in both directions, the rectifier
is defective and the rectifier must be replaced.
NOTE
○
The actual meter reading varies with the meter used
and the individual rectifier, but, generally speaking, the
lower reading should be from zero to one half the scale.
NOTICE
If a megger or a meter with a large-capacity battery
is used, the rectifier will be damaged.
Regulator Inspection
•
Set the hand tester to the 1 kΩ range.
Special Tool - Hand Tester: 57001-1394
•
Check the resistance between F [A] and B [B] terminals
in both directions.
○
The resistance should be low in one direction and more
than ten times as much in the other direction.
If the reading shows low or high in both directions, the
regulator [C] is defective and must be replaced.
Alternator Ball Bearing Inspection
NOTICE
Do not disassemble the alternator for bearing in-
spection since disassembling the alternator dam-
ages the bearings.
•
Turn the alternator rotor shaft back and forth while check-
ing for play, roughness or binding of bearings.
If bearing play, roughness, or binding is found, disassem-
ble the alternator and replace the bearings.
