Johnson J10RSRD User Manual

To check stator for a grounded condition, connect
one meter
lead to a clean engine ground and the
other
lead alternately to the yellow/blue, yellow
and yellow/gray stator leads:
•
Ohmmeter should show a high reading.
• If ohmmeter shows a low reading, stator is
grounded.
If a stator lead
is grounded, repair it or replace the
stator
assembly.
Rectifier Resistance Tests
Disconnect battery cables at the battery.
STEP 1
Disconnect all rectifier leads from terminal board.
Calibrate ohmmeter on appropriate scale. Con-
nect one
lead to a clean engine ground. Connect
the other
lead to the rectifier yellow/gray lead.
Note the reading. Reverse the ohmmeter connec-
tions or press the "reverse
polarity" button and
note the reading. Perform the same procedure
on
the yellow and yellow/blue rectifier leads. Note the
readings.
• A high reading in one direction and a low read-
ing
in the other direction indicates the diode is
OK.
•
Two high readings or two low readings indicate
the diode
is damaged.
STEP 2
ELECTRICAL
CHARGING SYSTEM TESTS
Move ohmmeter lead from engine ground to recti-
fier red
lead. Connect the other meter lead to the
yellow/gray rectifier leads. Note the reading.
Reverse the ohmmeter connections or press the
"reverse
polarity" button and note the reading.
Perform the same procedure on the
yellow and
yellow/blue rectifier leads. Note the readings.
• A high reading
in one direction and a low read-
ing
in the other direction indicates the diode is
OK.
•
Two high readings or two low readings indicate
the diode is damaged.
Replace the rectifier if test results vary.
