Probable Cause
1. Blown console fuse
2. Poor battery connection
3. Low battery voltage
4. Defective console
Corrective Action
1. Check fuse (located near battery connection). If needed, replace with
5.0 A fuse maximum. If fuse blows again, check all harnesses for
pinches or breaks that may cause power short to ground.
2. Be sure connections are clean and tight. Inspect harness for damage.
3. Console voltage must be at least 10 V. If low, recharge or replace
battery.
4. Console is damaged. Contact your dealer, DICKEY-john USA
(1-800-637-3302), or DICKEY-john Europe (011-33-141-192189).
ROW FAILURE OR HI/LOW ALARM WHEN ROW IS
PLANTING PROPERLY
Probable Cause
1. Seed sensor coated with dirt
2. Faulty sensor or harness
3. Defective console
Corrective Action
1. Clean sensor using a dry bottle brush.
2. Drop seed down the seed tube or place a dry bottle brush down the
seed tube to trigger sensor. Observe if troubleshooting sensor LED
mounted to the tube blinks. If sensor does not blink, replace the
sensor. If the sensor LED blinks, check harness for damage or
pinched wires. If the sensor does not have an LED, swap harness
connection with adjacent sensor to determine if sensor is damaged.
3. Console is damaged. Contact your dealer, DICKEY-john USA
(1-800-637-3302), or DICKEY-john Europe (011-33-141-192189).
