TEST PROCEDURE

RESULT

COMPONENT

Terminal-To-Terminal

Set the ohmmeter to the

R x 10 k

scale, and measure the resistance
across the capacitor terminals.

High-Voltage Capacitor

a) Normal - The meter indi-

cates several ohms, then
gradually returns to in-
finity.

b) Abnormal - The meter

indicates infinity, or zero
ohms (a short) immedi-
ately.

Terminal-To-Case

Set the ohmmeter to the

R x 1

scale, and measure the resistance
between each terminal and the
case.

a) Normal - The meter indi-

cates infinity.

b) Abnormal - The meter

indicates zero ohms, or
a short.

Blower Motor Capacitor

Terminal-To-Terminal

Set the ohmmeter to the

R x 10 k

scale, and measure the resistance
across the capacitor terminals.

a) Normal - The meter indi-

cates several ohms, then
gradually returns to in-
finity.

b) Abnormal - The meter

indicates infinity, or zero
ohms (a short) immedi-
ately.

a) Normal - The meter indi-

cates several ohms.

b) Abnormal - The meter

indicates infinity, or zero
ohms (a short).

Forward Continuity

Set the ohmmeter to the

R x 1

scale, and measure the forward
resistance across the rectifier ter-
minals with the (+) lead touching
the anode and the (–) lead touch-
ing the cathode.

High-Voltage Rectifier

a) Normal - The meter indi-

cates infinity.

b) Abnormal - The meter

indicates infinity, or zero
ohms (a short).

Reverse Continuity

Set the ohmmeter to its highest
scale, and measure the reverse
resistance across the rectifier ter-
minals with the (+) lead touching
the cathode and the (–) lead touch-
ing the anode.
