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.

10.3.1.3 HarnessRe-Conguration
A new auxiliary harness can be recongured
to draw power from a dierent source if the
supplemental harness isn’t installed on the tractor,
or if there are issues with the J560 connector
connection.
Refer to Figure 10.15.
The factory default for the main auxiliary harness
will draw power from the Tractor J560 connector
when the tractor is switched on, and will also
switch on the relay to draw power directly from
the battery, if the supplemental power harness is
installed and connected to the tractor battery.
1. There is a diode in the harness to prevent the
battery power from feeding back to the tractor
J560 Connector when the tractor power is
switched o.
If the supplemental power harness is not installed,
follow the labels on the single pin connectors
(Figure 10.15) at the front of the main auxiliary
harness on the tank, and disconnect it to leave the
relay switched o.
1. Power will be supplied solely by the J560
Connector coming from the tractor when it is
switched on.
As a temporary solution, if the J560 Connector is
not turning on from the tractor, or it has a poor
connection and is not supplying enough power to
switch on the relay at the tank, follow the labels
on the single pin connectors at the front of the
main auxiliary harness on the tank and connect the
one labeled for constant battery power.
1. This will supply constant battery power from
the tractor, through the supplemental harness
until the problem with the harness is resolved.
2. You would need to disconnect from the tractor
when shutting down, to stop drawing power
from the tractor when it is switched o. This
will prevent killing the tractor battery.

10.3.2 Brake System
10.3.2.1 Bleeding Brakes - Surge Brakes
Completing a full system bleed including the
calipers requires the use of Bourgault Surge
Brake bleed pump. Contact your dealer for more
information, parts and instructions.
As part of the 50 hour maintenance program, air
should be removed from the air trap located above
the front axle.
Refer to Figures 10.16 & 10.17.
To remove the air from this trap, complete the
following steps:
1. Compress the master cylinder by quickly
pushing backwards (reversing) on the air
seeder hitch.
a. This will pressurize the brake system.
2. Place the tractor in park without relieving any
of the compression on the air seeder hitch as it
is important to have the system pressurized.
3. Locate the needle valve and slowly open the
valve until uid is present, then quickly close
the valve.
a. Use a rag to wipe up any drops of uid.
4. Removing the air from the air trap at 50 hour
intervals will ensure that any air in the system
does not reach the brake calipers.
a. Air in the surge brake system can greatly
reduce braking performance.
CAUTION
The hitch compression method may cause the
machine to roll slightly as the brakes are being
bled.
Use caution when bleeding the calipers if the
hitch compression method is being used. If a
signicantamountofuidisrequiredtobleed,the
hitch compression method is not recommended,
use the bourgault bleed pump instead.
The hitch compression method can be used to
purge any air out of the calipers that may have
settledovertime,butisnoteffectiveforushing
air out of the lines.

10.3.2.3.3 Surge Brake System Pressure
1. Drive the air seeder forward, creating tension
in the hitch which will allow the brake system
to reset to tank pressure (0 PSI).
a. The following steps will be easier if the air
seeder is pointed slightly downhill (front
wheels being lower than the rear wheels),
and/or there is some product in the tank as
this will add resistance while reversing.
2. Reverse the air seeder, causing compression in
the hitch.
a. This may require the air seeder to travel a
couple inches or a couple feet depending
on the resistance of the air seeder.
b. As soon as the hitch is compressed, stop
the tractor and place in park without
removing the compression in the air seeder
hitch.
3. Read the pressure gauge on the surge brake
manifold. Refer to Figures 10.16 & 10.17.
4. This gauge should read at least 550 PSI while
the compression is maintained in the hitch after
the above procedure.
a. If the system does not maintain 550 PSI or
more, repeat the procedure.
i. Brake bleeding may be required
if the brake system does not build
adequate pressure.
Note
The brake system pressure may be much higher
than 500 PSI.
During hitch compression, pressure may read
above 2000 PSI but will stabilize well below 2000
PSI.

10.3.3 Main Transfer Bellows Preload
Setting
It is important to set some compression (preload)
to the air seeder bellows. The preload will give
the bellows enough stretch when the seeding unit
is turning in the headlands. Not enough preload
may result in the b ellows pulling out of the main
transfer pipe.
Important
Instructions are given for a single transfer line,
complete the process for each transfer line on the
unit.
10.3.3.1 Bellows Preload Setting - Trailing Units
1. Ensure the primary elbow is fastened to
the primary bracket, located on the steering
knuckle at the correct height. Refer to 10.20.
2. Ensure that the primary elbow is directly in
line with its s-pipe to ensure proper product
distribution.
a. Verify the front hitch is centered and
front axle is level, (unit is parked on level
ground). See Figure 10.21.
b. Zero a digital level to frame rail, refer to
Figure 10.22.
c. Tip the primary stand rearward until the
stand is vertical in both directions.
d. Tighten the primary stand hardware.
e. Check alignment of primary elbows to the
s-pipe using a straight edge, without the
bellows installed.
