Checking Voltage Range from Combine Cab
Before checking voltage range, follow these steps:
1. Position header 150 mm (6 in.) above ground, and unlock adapter float.
2. Check that float lock linkage is on down stops
(washer [A] and nut [B] cannot be moved) at both
locations.
NOTE:
If header is not on down stops during next two steps,
voltage may go out of range during operation causing a
malfunction of AHHC system.
3. The pointer (A) on float indicator box should point at 0.
If it does not point at zero, adjust cable take-up
bracket (B) until it does.
