Note: Since the tilt actuator will not operate,
it is only possible to check for one condition.
Pick the condition below that best describes
the position of the tilt system.
9.
Example 1, the tilt is in mid-stroke. The
value recorded is the resistance through the
actuator motor windings. If this reading is not
correct, replace the tilt actuator and retest.
Note: The value recorded in one direction is
the forward resistance through a diode and
will vary with the type of Multimeter used.
This value is not important, as long as there
is continuity in one direction only. This value
may even be high. The value recorded in the
other direction is across the open contact of
the end of stroke micro-switch and should be
open.
10. Example 2, the tilt is in the full down
position. If the readings are not correct, replace
the tilt actuator. Refer to Tilt Actuator and Micro-
Switch Removal section this manual. Retest as
necessary.
Note: The value recorded in one direction is
the forward resistance through a diode and
will vary with the type of Multimeter used.

Example 3, the tilt is in the full up position. If the
readings are not correct, replace the tilt actuator.
Refer to Tilt Actuator and Micro-Switch Removal
section this manual. Retest as necessary.
