MEASURING WINDING RESISTANCE
Check the resistances of the leads from the stator with a
tester. (See Fig.
9
-
1
.)
Check all the leads mrhich are shown by type in the tables
below.
Any
lead which is inactive is faulty.
NOTE: Testers are not
so
accurate that some margin
of
er-
ror must be taken into account when reading the tester
against the values shown in the Tables
9-
I,
9-2,
and 9-3.

WINDING RESISTANCE MEASURING
SLIP
RING
Check the resistance between the two
slip
rings with a test-
er. (See
Fig.
9-2.)
The resistance is normal if it is anywhere from
6
ohms
to
13
ohms.
