2.5 Knee Section Does Not Lower
The knee section does not lower when the footboard foot down switch is
activated.
1. Set your VOM to measure V AC. At J/P12, place the black probe into pin 4
and the red probe into pin 2 (see figure 3-19 on page 3-11). Activate the
footboard foot down switch. The voltage is approximately 120V AC.

If the AC voltage is more than 175V AC, the knee drive does not
work (refer to procedure 4.25).
If the AC voltage is approximately 0V AC, then the knee motor
does not work (refer to procedure 4.20).
If the voltage is approximately 120V AC, the knee capacitor
does not work (see figure 2-7 on page 2-23).
