5. Use a voltmeter to measure the voltage between the
ground (Pin 2) and signal (Pin 3) wires of the AHHC
sensor (A) at the back of the float module side frame.
Ensure it is at the high voltage limit for the combine.
Refer to Table 3.20, page
NOTE:
The wiring harness connector must be attached to the
sensor. Do NOT disconnect it.
6. Repeat at the opposite side.
7. Fully lower the combine feeder house, and float the
header up off the down stops (float indicator [A] should
be at 4, and the float module should be fully separated
from the header).
NOTE:
You may need to hold the HEADER DOWN switch for a
few seconds to ensure the feeder house is fully
lowered.
8. Using a voltmeter, measure the voltage between the
ground (Pin 2) and signal (Pin 3) wires of the AHHC
sensor (A) at the back of the side frame. Ensure it is at
the low voltage limit for the combine. Refer to
Table 3.20, page 126.
NOTE:
The wiring harness connector must be attached to the
sensor. Do NOT disconnect it.
9. If the sensor voltage is not within the low and high
limits, or if the range between the low and high limits is
insufficient, adjust the voltage limits. Refer to
Voltage Limits: Two-Sensor System, page
10. Repeat at the opposite side.
