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 approximate flow
where the EPD kicks out. If this is below the flow you need you will need to reduce system pressure by:
•
Looking 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 (
highlighted green,
shown on the right
) to each other. This will bypass
the module and supply 12 volts directly to pumps.
2. Do the pumps run? If not, check the 40 amp fuse
on the EPD harness that is connected to the trac-
tor battery. Inspect harnesses and connections.
Make sure wire colors match up. (white/white,
black/black)
3. If using a dual pump system, test each pump by
plugging one pump at a time directly to the bat-
tery.

Inspect connections for burned out connectors.
Inspect all connections for bent or burned out leads. Constantly running the system at a
high pressure or getting more than the required voltage (12v) can result in burned out
connections causing the system to not work properly.
