Return path to the CM for the voltage used to operate the first left of center yellow LED of the drive wheel direction icon on the Supplemental Display.
Illuminated: <1V Not illuminated: 12V

CM
ROTATE POT
Input to the CM from the Rotate Position Feedback Pot (VR6). The CM uses this voltage to determine the rotated position of the forks and the rate that they are moving during Learn.
Nested full right: 3.5 to 4.5V Centered: 2.25 to 2.75V Nested full left: 0.5 to 1.5V

JPC24-18
TRAVERSE POT
Input to the CM from the Traverse Position Feedback Pot (VR5) via JPK-2. The CM uses this voltage to determine the position of the traverse assembly and the rate that it is moving during Learn.
Nested full right: <4.5V Nested full left: >0.4V
