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.
8. Tilt is in mid-stroke. (Fig 5.8.1)
The value recorded is the resistance through the
actuator motor windings. If this reading is not
correct, replace the tilt actuator and retest.
10. Tilt is in the full down position. (Fig 5.8.2)
If the readings are not correct, replace the tilt
actuator.
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.
11 Tilt is in the full up position. (Fig 5.8.3)
If the readings are not correct, replace the tilt
actuator.
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.
