Testing a Switch for Continuity
Place one probe on one contact of the switch. Place the
second probe on the second terminal of the switch (Ref.
Fig. 8).
Actuating a normally open (NO) switch will cause the
DVOM to show “0” or give an audible indication when the
switch is operated. A normally closed (NC) switch will
cause the meter to show “0” or give an audible indication
when the probes are attached without activating switch.
The audible indicator will stop and the meter display will
indicate a value greater than “0” when the switch is acti-
vated.
The change in display or audible indicator shows that the
switch is functioning.

Testing a Solenoid for Continuity
Place one probe on one of the large terminals and the
other probe on the second large terminal (Ref. Fig. 9). If
the meter shows “0” or gives an audible indication, the
solenoid terminals are “welded” closed and the solenoid
must be replaced.
If the continuity test indicates that contacts are not
“welded” and the wiring to the solenoid coil is good, the
coil has failed and the solenoid must be replaced.
