Regulator/Rectifier Inspection
•
Remove:
Connectors [A] (disconnect)
Bolts [B] and Regulator/Rectifier [C]
Rectifier Circuit Check
•
Check conductivity of the following pair of terminals.
Rectifier Circuit Inspection
W-BK1, W-BK2, W-BK3,
Tester connection
BK/Y-BK1, BK/Y-BK2, BK/Y-BK3,
The resistance should be low in one direction and more
than ten times as m uch in the other direction. If any two
leads are low or high in both directions, the rectifier is
defective and must be replaced.
NOTE
○
The actual meter reading varies with the meter and the
individual rectifier. Generally speaking the lower read-
ing should be from zero to one half of the scale.
Regulator Circuit Check
To test the regulator out of circuit, use three 12 V batteries
and a t est light (12 V 3 ∼ 6 W bulb in a socket with leads).
CAUTION
The test light works as an indicator and also a cur-
rent limiter to protect the regulator/rectifier from ex-
cessive current. Do not use an ammeter instead of
a test light.
•
Check to be sure the rectifier circuit is correct before con-
tinuing.
Regulator Circuit Test-1st Step
•
Connect the test light [A] and the 12 V battery [B] to the
regulator/rectifier [C] as shown.
•
Check Y1, Y2, and Y3 terminal respectively.
If the test light turns on, the r egulator/rectifier is defective.
If the test light does not turn on, continue the test.
