(black) & 8 (white) and 3 (red) & 8 (white) of the INCLINE
connector. Terminals 3 (red) & 4 (black) should read
approximately 1K W (Ohms). The sum of the readings between
terminals 4 (black) & 8 (white) and 3 (red) & 8 (white) should
total approximately 1K W (Ohms). If either reading is
significantly high or open, replace the lift motor.
NOTE: Readings While The Unit Is In The Home Position (Level)
 Potentiometer resistance black to red = approximately 1kW.
 Potentiometer resistance black to white = 20% of black to red
(approximately 200W)
 Potentiometer voltage black to red = approximately 3.3 volts.
 Potentiometer voltage black to white = 20% of black to red
(approximately 0.66 volts)
 A/D value = approximately 6200
3 Refer to the lift calibration procedure. If the lift position number
and physical lift position measurement does not correspond with the
service manual, calibrate the lift motor.
Note: There must be a reason for the lift motor to be out of calibration,
therefore simply re-calibrating the lift motor will often not fix the
problem.
4 If the lift calibration number (A/D value) is not 0 or 65535 and
does not increment when the lift motor moves, replace the lift
motor.
