Near Intersection of I-35 & I-90 Southern Mn. | Some of you may be testing your Ag Leader Direct Command setups for spraying prior to season. A fairly common complaint I used to hear as a Tech was. "Everything seems OK but I can't get the section valves to turn ON. It was fine last year".
Here are some things to check:
1) Are you certain that the Liquid Product Control module (true for other modules as well) has High Current Power and Ground? The only way to determine this is to temporarily unplug the 2 pin Deutsch connector on the Red and Black wires at the module. Use a meter and test the incoming Red wire to the Black wire for 12V. Test between the Red and Black and not to the frame. Remember the flashing green LED on the module indicates that the CAN communication between the module and the display is healthy. It does NOT confirm that the High Current Power and Grounds are Healthy. You must use a meter.
2) Is auto swath inactive? If auto swath is set to active, it might be preventing the system from turning on the valves.
3) Is the target rate set to some value other than zero? The system will NOT open the section valves if the rate is zero. If you choose a "new" product, the rate will default to zero, the first time you select it. After that it will default to the last rate used for that product.
4) Do you have a working implement switch? If you don't have an implement switch, the connection must have a jumper inserted in the connector. Without a working implement switch in the application position or a jumper, the valves will NOT open.
There are other possible reasons for the problem but checking the above will catch the majority.
