The Trailerteck T05 Model has been tried
and tested by top fleets across North America. It makes trailer inspections
fast and simple and provides a valuable troubleshooting tool.
Here are some of it’s capabilities:
Simply connect the T05 to the front of the trailer, then walk around the
trailer with the remote to easily confirm that electrical and pneumatic
systems are operating normally..
Check for Air leaks
Activate both the Emergency and Service brake functions and allow the
air pressure to stabilize. Shut off the manual air entry valve to prevent
the air from flowing into the device and the trailer. Since the device
is air tight, a pressure drop on one of the two the pressure gauges means
an air leak in the corresponding air circuit of the trailer.
Check for Electrical problems
The built in ammeter can help find electrical problems such as faulty
connections or corrosion. Electrical problems have a tendency to create
resistance, which generates heat, which then causes the amperage draw
to rise slowly.
Activate all the electrical functions
and wait for approximately one minute for the current draw to stabilize.
If you see a continuous but slow increase in the amperage draw, 0.1 Amp
at a time, this is an indication of an electrical problem.
If this is the case, Turn off all the lights then isolate each circuit
by bringing the light circuits on individually until you find out in which
electrical circuit is creating the problem.
If a short circuit is found in one of the activated functions, the corresponding
light will blink on the control panel. At the same, a sound signal will
be heard until the function is deactivated or the short circuit fixed.
If there is a ground problem on the trailer, during the inspection, the
Trailertteck device will exhibit unpredictable behavior. That happens
when the activated functions on the trailer don't match the signals sent
by the remote.
If you suspect a faulty ground circuit, simply connect the T05 Ground
Lead clip to good ground source on the trailer and observe if there are
If you are able to eliminate that problem, this confirms that you have
a faulty ground circuit.
