ELECTRICAL SYSTEM 14-35
Charging System
•
Do the 2nd step regulator circuit test.
○
Connect the test light and the 12 V battery in the same
manner as specified in the “1st step regulator circuit test”.
○
Apply 12 V to the positive (+) terminal.
○
Check infinity ( ∼ ) terminals respectively.
If the test light turns on, the regulator/rectifier is defective.
Replace it.
○
If the test light does not turn on, continue the test.
•
Do the 3rd step regulator circuit test.
○
Connect the test light and the 12 V battery in the same
manner as specified in the “1st step regulator circuit test”.
○
Momentarily apply 24 V to the positive (+) terminal by
adding a 12 V battery.
○
Check infinity ( ∼ ) terminals respectively.
CAUTION
Do not apply more than 24 volts. If more than 24
volts is applied, the regulator/rectifier may be dam-
aged. Do not apply 24 V more than a few seconds.
If 24 volts is applied for more than a few seconds,
the regulator/rectifier may be damaged.
If the test light does not light when 24 V is applied momen-
tarily to the positive (+) terminal, the regulator/rectifier is
defective. Replace it.
If the regulator/rectifier passes all the tests described, it
may still be defective. If the charging system still does
not work properly after checking all the components and
the battery, test the regulator/rectifier by replacing it with
a known good unit.
•
Repeat the test for another regulator/rectifier.
