Checking Voltage Range from the Combine Cab (John Deere S Series)
NOTE:
Changes may have been made to the combine controls or display since this document was published.
Refer to the combine operator’s manual for updates.
To check the sensor output voltage range from the combine cab, follow these steps:
1. Position the header 6 in. (150 mm) above the ground.
Unlock the adapter float.
NOTE:
If the header is not on down stops during the
next two steps, the voltage may go out of range
during operation, causing a malfunction of the
Auto Header Height system.
2. The pointer (A) on the float indicator box should point
at zero. If it does not point at zero, adjust the cable
take-up bracket (B) until it does.
