Why Dickey-John Control Point console does not power on?
- N
  nboyleAug 14, 2025
  If your Dickey-John Control System console won't power on, first, check the fuse in the positive battery lead and replace it if it's blown, using the same size blade-type fuse. Next, inspect battery connections for corrosion and ensure correct battery polarity. Then, check the red ignition wire and the power cable from the console to the battery for damage, replacing or repairing as needed. If these steps don't solve the problem, the console itself may be faulty.

What to do if AUTO is inoperative, but UNLOAD operates on Dickey-John Control Systems?
- D
  dthorntonAug 17, 2025
  If the AUTO function isn't working but UNLOAD operates on your Dickey-John Control Systems, the ground sensor might be the issue. First, check the ground speed reading (MPH) on the console. If it reads 0 while the truck is moving, inspect the wires and connections between the Dickey-John ground speed sensor and the console, and between the sensor and the transmission speed sensor. Next, check the ground speed calibration number (F7) in the console, ensuring it's between 35000 and 60000. If problems persist, replace the ground speed sensor, and if needed, the MASTER switch module and then the console.

How to fix application rate error on Dickey-John Control Point Control Systems?
- A
  Andrea MillerAug 21, 2025
  If you're encountering an application rate error with your Dickey-John Control Systems, first, reduce the truck's ground speed to allow the system to catch up. You can also shift to a lower gear to increase engine RPM and hydraulic pump rotation. Check the hydraulic disconnects and filter. Ensure the correct spreader constant is programmed into the console by checking the original setting or running a Granular Calibration (F6). Also, verify the PWM SAT setting in the Granular Configuration screen (F3) against the original or run System Response on the Granular channel (F11). Finally, check for sufficient hydraulic oil flow at normal engine RPM, and inspect the spreader valve, electrical connections, coil resistance, and voltage from the control console.

What to do if MANUAL MODE flashes on Dickey-John Control Point Control Systems display?
- R
  rvincentAug 25, 2025
  If 'MANUAL MODE' is flashing on your Dickey-John Control Systems display, here's what to check: * If material isn't spreading (conveyor or auger stopped): * Ensure the PTO is engaged. * Check for lodged obstacles in the conveyor or auger. * Check for a hydraulic system failure (pump, valve, hydraulic motor). * If material is spreading (conveyor or auger turning): * Check for a disconnected or slipping conveyor sensor coupling. * Unplug the connector nearest the conveyor sensor and check for +12V between the RED and BLK wires and +8V between the GRN and BLK wires. Absence of either voltage indicates a broken or shorted wire or a corroded pin. If voltages are present, replace the conveyor sensor.

Why does the displayed APR fluctuate on Dickey-John Control Point?
- D
  Dr. Emily Holmes MDAug 27, 2025
  If the displayed APR fluctuates on your Dickey-John Control Systems, it could be due to the System Response (SYS RSPNS) constant being too large. Also, check the APR sensor for loose coupling or slipping on the shaft.

How to correct spinner rotational speed on Dickey-John Control Point Control Systems?
- M
  Maria AdamsAug 31, 2025
  If the spinner rotational speed is incorrect on your Dickey-John Control Systems, start by checking the PWM OFFSET and PWM settings in SPINNER mode (F8). Also, check for variations in granular material density dropping onto the spinners. For proportional valves, increased electrical coil resistance due to heat can cause speed changes. Finally, check for drag due to snow and ice buildup.

What to do if convey/auger does not reach maximum speed on Dickey-John Control Point?
- H
  Hannah MartinSep 2, 2025
  If the conveyor/auger on your Dickey-John Control Systems isn't reaching maximum speed, you can try the following: repair the hydraulic system, eliminate any binding, adjust to the proper pressure or replace the valve, clear any obstructions, or shift to a lower gear and/or axle.

Why displayed APR responds slowly on Dickey-John Control Point Control Systems?
- R
  Ryan BensonSep 6, 2025
  If the displayed APR responds slowly on your Dickey-John Control Systems, the System Response (SYS RSPNS) constant may be too small.

What to do if conveyor/auger does not run in either AUTO or UNLOAD on Dickey-John Control Systems?
- M
  Manuel PhamSep 9, 2025
  If the conveyor/auger on your Dickey-John Control Systems isn't running in either AUTO or UNLOAD mode, try the following: engage the pump, open the valve, reconnect any disconnections, clear any jams, adjust or replace parts as needed, and repair any leaks and refill the oil.
