CHARGING SYSTEM TESTS
Stator Resistance Tests
9.9/15 MODELS
Disconnect battery cables at the battery.
Disconnect
all stator leads.
Calibrate
ohmmeter on appropriate scale. Con-
nect meter
leads between the two stator yel-
low/gray leads.
•
Ohmmeter must show a low reading.
• If ohmmeter shows a high reading, repair lead
between the two yellow/gray connectors, or
replace stator.
DR4816
Connect meter leads between the yellow and yel-
low/gray
stator leads.
•
Ohmmeter must show 0.80 to 0.90 ohms.
Connect meter
leads between the yellow and yel-
low/blue
stator leads.
•
Ohmmeter must show 0.80 to 0.90 ohms.
Connect meter
leads between yellow/blue and
one
yellow/gray lead.
•
Ohmmeter must show 1.5 to 1.7 ohms.
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.
86
If a stator lead is grounded, repair it or replace the
stator
assembly.
DR4818
25/30 MODELS
Disconnect battery cables at the battery.
Disconnect
all stator leads from terminal board.
Calibrate ohmmeter on appropriate scale. Con-
nect meter
black lead to the stator yellow/blue
lead.
Connect meter red lead to the stator yellow lead.
•
Ohmmeter should show 0.55 ± 0.05 ohms.
Move the meter
red lead to the stator yellow/gray
lead.
•
Ohmmeter should show 0.55 ± 0.05 ohms.
