the bridge fails even one test,
it
must be replaced.
Using the chart
at
the right, connect the meter wires as
indicated by the black dots for each
test,
then check
the
continuity.
In
Tests
1,
2
and
3,
there should be
NO
continuity.
In
Tests
4,5.and
6,
connect the
+
and
-
meter
wires
as
indicated, check continuity, then switch the meter wire
connections and check continuity again.
You
should
get
NO
continuity one way, and
YES
continuity the
other way.
