4. Adjust the cable take-up bracket (B) (if necessary) until
the pointer (A) on the float indicator is on 0.
5. Use a voltmeter (A) to measure the voltage between the
ground (Pin 2) and signal (Pin 3) wires at the AHHC
sensor in the float indicator box. Ensure it is at the high
voltage limit for the combine. Refer to Table
126.
NOTE:
The wiring harness connector must be attached to the
sensor. Do NOT disconnect it.
6. Fully lower the combine feeder house, and float the
header up off the down stops (float indicator 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.
7. Use a voltmeter (A) to measure the voltage between the
ground and signal wires at the AHHC sensor in the float
indicator box. It should be at the low voltage limit for the
combine. Refer to Table
NOTE:
The wiring harness connector must be attached to the
sensor. Do NOT disconnect it.
8. 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
