Measure the resistance.
(Ohm-meter scale: Rx1000)
• Terminal to terminal.
Normal: Momentarily indicates
several ohms, and
then gradually returns
to infinite.
Normal: Infinite.
Normal: Continuity.
Abnormal: Infinite.
Normal: Infinite.
Abnormal: Continuity.

• Terminal to case.
Measure the continuity (Forward).
(Ohm-meter scale: Rx10000)
Measure the continuity (Reverse).

NOTE :
Some inexpensive meters
may indicate infinite
resistance in both direction.
