10.3.1.1.2 Suggestions
1. Refer to
Figure 10.14
. A long wire can be
used to extend to one of the meter leads to
check the continuity from a pin on one harness
connector to the corresponding pin at another
connector on the harness.

2. When possible, disassemble the connectors of
a suspect harness and check for visible signs
damage, such as broken wires or wires which
have come out of their screws.
a. If the fault is not visible, the harness may
need to be replaced.
3. If, after disassembling the connectors, no
obvious faults have been found, check that
the correct colored wires are connected to the
connector positions according to the wiring
diagrams (this assumes that the system has
not previously functioned properly with all the
same equipment it now has).
a. The harness may be incompatible with the
system that has been introduced.
10.3.1.2
Repairing Metri-Pack Connector Faults
If a Metri-Pack connector, at any junction shows
signs of damage, disassemble the connector
and look for problems. Refer to the following
guidelines:
1. Remove the cover on the connector.
2. Clean all soil away from the pins as necessary.
Check for broken or shorted wires and repair
or replace.
3. Check if the correct color wires go to the right
pins as outlined in the wiring diagrams.
10.3.1 Implement Harness Checking
Most problems with agricultural electronics are
mechanical in nature. Problems with the harness
connections are the most common.
10.3.1.1
Harness Checking
If a problem occurs with the continuity of the
implement harness, check for broken connections,
loose terminals or loose wires in the connectors at
each terminal of the harness. A multi-meter can
be used to check voltage in the wiring harness
or resistance in the harness when checking for
continuity. Refer to
Section 13 - Schematics
and
the
X35 Operator’s Manual
.
10.3.1.1.1
Voltage Measurements
These measurements should be done on equipment
that is powered up.
With the harness powered up, the voltage;
1. Between supply and ground at a valve, light,
etc.;
2. Between supply and harness junction after the
monitor;
a. Should be within 10% of the voltage
between the incoming supply and ground
(the two wire connection from the battery
to the monitor or the pins on the tractor’s
J560 connector).
3. For example:
a. In one reading, the tractor’s voltage
between the WORKLIGHTS PIN and
GROUND at the rear J560 connector was
measuring 13.6V, while the supply to a
work light on the air seeder was 12.9V.
b. If the measured voltage is much less than
10% of the tractor’s measured voltage it
may indicate a dirty or poor connection.
c. If there is no measured voltage it indicates
there is no continuity in the circuit.
