NOTE: Prior to taking small resistance readings with a
digital multi meter, short the meter test leads together.
The meter will display a small resistance value (usually
0.5
ohms or less). This resistance is due to the internal

resistance of the meter and test leads. Subtract this val-
ue from from the measured value of the component you
are testing.

minals 30 and 87. Ground terminal 86 and apply +12
VDC to terminal 85. The relay should make and break
continuity between terminals 30 and 87 as +12 VDC is
applied and removed from terminal 85.
