2. The pointer (A) on float indicator should point at 0. If it
does not, adjust cable bracket (B) until pointer (A) on
float indicator points to 0.
3. Measure voltage between ground and signal wires at
AHHC sensor in float indicator with a voltmeter (A).
NOTE:
The voltage reading should be below 4.3 V.
4. Fully lower combine feeder house until adapter is no
longer supporting header. The float indicator should
read 4.
NOTE:
You may need to hold HEADER DOWN switch for a few
seconds to ensure feeder house is fully lowered.
5. Measure voltage between ground and signal wires at
AHHC sensor in float indicator with a voltmeter (A). It
should be at low voltage limit for combine – 0.7 V.
6. If sensor voltage is not within low and high limits, or if
range between low and high limits is less than 3.0 V,
make adjustments according to
Limits, page
243.
