Pumps run for a few seconds then turn off
This symptom is due to the pumps drawing more current than the 40 amp limit of the EPD.
1.
Unplug the EPD connector going to the battery for 2-3 seconds. Removing power from the EPD
resets it.
2.
Go to Diagnostics, Section Test to investigate this issue.
3.
In Section Test, hold down “+” button for a few seconds. A single tap of this button produces a
very small change in signal to the valve, so you must hold it.
4.
Increase the flow slowly, checking the “1,2,3” screen to see you flow in GPM. Find the ap-
proximate flow where the EPD kicks out. If this is
below the flow you need you will need to reduce
system pressure by:
•
Look for any unintended restrictions or
plugged rows
•
Increase orifice size
•
Reduce ground speed
•
Reduce application rate
Electric pumps will not turn on
Connect pumps directly to battery
1.
Find the EPD (electric pump driver) shown at
right. Connect the two connectors circled to each
other (bypass the module and supply 12 volts di-
rectly to pumps)
2.
Do the pumps run? If not, check the 40 amp
fuse in the EPD harness near the tractor battery.
Inspect harnesses and connections.
3.
If 2 pump system, plug pumps in by themselves to check both.
Electric pumps only run w/ 12 volts direct from battery
Connect pumps and power harness back to EPD.
1.
Go to Rate Control Detail screen to investigate this issue.
2.
Turn system on and press the increase button .
3.
Remove PWM valve connector and check voltage. You will need 1-12 volts to turn pumps on.
4.
If 1-12 volts is not present, check harnesses and review control valve type setup.
5.
Go back to the Liquid Product Control Module . Check voltage between pins 2 & 7 on the 8-pin
connector. There should be between 6-12 volts while in section test after holding increase but-
ton in Manual mode.
6.
If you cannot get voltage at pins 2 & 7, contact your AgLeader dealer for further assistance.
