Bridge
Test
Remove the bridge from the pressure control box and
tional. See
BRIDGE RECTIFIER REPLACEMENT,
perform this test to determine if the bridge is func-
set on the X1 ohms scale.
page 21. Use a continuity tester, such
as
multi-meter
All
tests must be performed.
If
the
bridge fails even
one test,
it
must be replaced.

shows the position
of
the
wires on the bridge.
Using the chart at the right, connect the meter wires
as indicated and then check the continuity.
