TROUBLESHOOTING GUIDE
UNIT WILL NOT POWER ON. NO LEDS WILL LIGHT
DURING THE POWER UP SEQUENCE.
Probable Cause:
1. Loose connection between power harness and monitor
2. Blown fuse
3. Defective monitor or main harness
4. Defective module, harness, or sensor
5. Poor battery connection
6. Insufficient system voltage
Corrective Action
1. Assure harness connections are centered and fully inserted. Assure
the main harness is properly connected to the monitor.
2. Assure the positive and negative connections are not reversed. Check
the fuse in the power harness near the battery. If it is blown,
troubleshoot and repair fault. Replace with a 7.5A AGC.
Do not replace fuse with one having a higher amperage rating - the
console could be damaged internally.
3. Disconnect implement main harness. Measure for short between red
(power) and black (ground) wires. If shorted, the power harness or the
console is faulty and requires repair or replacement. Contact your
Parts and Service Dealer or call DICKEY-john in the U.S.A. at
1-800-637-3302.
4. Disconnect the system at the hitch and measure for short between red
(power) and black (ground) wires. If shorted, isolate by disconnecting
harnesses until fault is found. Contact your Parts and Service Dealer or
DICKEY-john in the U.S.A. at 1-800-637-3302. Outside of the U.S.A.,
contact your dealer or national distributor or DICKEY-john Europe at
00 33 (0) 1 41 19 21 80.
5. Check battery connections and assure they are clean and tight.
6. Make sure battery voltage is between 11 and 16 Vdc.
