your MUTT®with anything other than a 12 or 24 volt DC
power source will destroy the internal circuitry and void your
warranty.
(Manufacturer’s Suggested Replacement: Group 31. MUTT®will auto detect 12 or 24
volts. If 24 volts is required, two smaller 12 volt batteries can be used, but they must
be wired in series.)
• Battery Voltage: 12/24V DC
• Battery Type: Lead Acid
• Battery Compartment Dimensions:
13.5" L x 11" H x 9.25" D
• Battery Protection: Inline 30 amp fuse for
overcharge
• Battery must be clean and leak free.
• Identify battery polarity.
• Attach ring terminal (with red heat-shrink) to
positive (+) side and ring terminal (with black
heat-shrink) to negative (-) side. Also see
warning indicators on page 4. Connections
must only be made to clean terminal rings.
• Any loose or corroded connectors may cause
misdiagnosis or result in erroneous readings.

PART 5: PRETESTING CHECKLIST
The pretesting checklist should always be completed prior to using the MUTT®
UNIT PLACEMENT
• Place the tester on a at, level surface.
• Chock trailer wheels to avoid rolling.
MAINTAIN CONNECTORS
Dielectric grease should be used on all connections to avoid corrosion. If a bad
connection exists at the terminal junction, you may get an erroneous reading and
the MUTT®will not work properly.
• Make sure you have a solid connection in the socket.
• Be certain the 7 pins in each plug are clean and spread to the proper size.
• Always check the MUTT® connector pins at the side of the MUTT®for proper
expansion. Over time, the pins may bend in slightly resulting in a poor connection
between the connector and the cable ends. A at head screwdriver can be used
to expand the pins until a tight connection is made.
TRAILER CONFIGURATION SET-UP
The 9004M Smart MUTT®is a microprocessor controlled diagnostic trailer tester
specically designed for testing lights and electric brakes on trailers with 4, 5, 6
round pin and 7 spade pin type connections. Every time you power up the tester, the
internal computer wants to know which type of trailer connection you are testing.
Note, this phase is known as Trailer Conguration Set-Up and is indicated by a high
speed ickering of the LEDs surrounding the Control Knob. If left untouched after
15 seconds, the tester will always default to a 7 spade pin conguration. However,
if the user is testing a 4, 5 or 6 round pin type trailer connection, this setting can be
adjusted by rotating the Control Knob counterclockwise to select the desired number
of circuits (as noted on the face panel). Trailer Conguration Set-Up is repeated each
time the unit is powered up.
Testing 4, 5, and 6 Round Pin Type Trailer Connections
The 9004M is hard wired to a 7 spade pin connector, located on the side of the
tester. Each unit is supplied with a plug-in adapter, which will adapt the 9004M to 4,
5 and 6 round pin type connections. To test trailers with these types of connections,
the adapter must be plugged in line between the tester and the trailer. The instruc-
tions above for Trailer Conguration Set-Up should be used for more efcient and
accurate testing.
Call 888-786-7899 with any technical questions.

PART 7: ELECTRICAL/LIGHTING TESTING
Complete the pretesting checklist prior to all testing procedures.
The MUTT® is microprocessor controlled and features a special diagnostic rmware,
designed to seamlessly integrate with your preferred methods of testing. The MUTT®
will power the selected electrical circuits and instantly alert you to any signs of a faulty
condition. To properly utilize the diagnostic features, a complete scan of the
trailer’s electrical system should be performed at the front of the trailer using the
MUTT®prior to a walk-around inspection. If any wiring faults are present, the MUTT®
will blink or sound, alerting you to the issue. Only a one-time, walk-around/visual
inspection is needed to conrm that each individual light bulb is properly illuminating.
NOTE: Some advanced functions may not be listed on the face panel, so it’s
important to read the manual in its entirety to ensure that you are getting the full use
of this diagnostic system.
7.1 SELECTING A CIRCUIT
Circuits can be selected for testing manually, via remote control or by initiating Auto
Cycle Mode.
OPERATING WITH MANUAL CONTROL
1. Turn the Control Knob to select a circuit. The Control
Knob is automatically set to Ground Integrity when
power is turned on.
OPERATING WITH THE REMOTE CONTROL
1. Press and release the UP ARROW to select the next
circuit in a clockwise rotation.
2. Press and release the DOWN ARROW to select the next
circuit in a counterclockwise rotation.
AUTO CYCLE MODE
Auto Cycle Mode automatically tests one circuit at a time
in a clockwise rotation.
1. Press and release the Control Knob. The Auto Cycle
Indicator should illuminate.
2. A 5-second delay commences before power is
automatically applied to the rst circuit.
3. Circuits are automatically tested one at a time in a clockwise rotation, starting from
the Ground Integrity Indicator.
4. To cancel Auto Cycle Mode, momentarily press and release or turn the Control Knob.
NOTE: Auto Cycle Mode does not work when Brake Light Circuits are selected.

15
7.2 GROUND INTEGRITY TEST
Each time the MUTT®is powered on, it automatically runs a Ground Integrity Test.
A good ground connection must be established for the MUTT®to operate a trailer’s
electrical system.
1. Immediately after power up, the green lights around the Control Knob will illuminate.
2. A solid/healthy ground connection is indicated by a steadily illuminated Ground
Integrity Indicator.
3. Bad/poor ground or bad cable condition is indicated by all of the LED’s blinking
simultaneously.
4. When one or more green circuit LEDs blink while the Ground Integrity Indicator
is steadily illuminated a solid ground has been established, but an open circuit has
been detected. Refer to OPEN CIRCUITS on pg. 16.
CHASSIS AND PIN GROUNDS
A poor ground warning may be an indication that the connected trailer is only wired
for chassis ground. There are two ground types. 1.) Pin Ground: The ground wire
from each light assembly is wired through the main harness up into the trailer plug.
2.) Chassis Ground: The ground wire from each light assembly is grounded directly
to the trailer chassis. Ground with the truck is established at the king pin.
GOOD GROUND BAD/POOR GROUND

16
7.3 FAULT INDICATION
OPEN CIRCUIT
The MUTT®senses no load which is often the symptom of a disconnected wire, cut
wire, poor pin connection or bad return ground. The MUTT®can detect open circuits
in two ways.
1. During Ground Integrity Test: An individual circuit will blink and no audible alerts
will be present.
2. During circuit selection: The selected circuit’s LED will blink, while simultaneously the
Open Circuit Indicator will ash. The MUTT®will also provide an audible alert (beep).
Example: The MUTT®detects an open circuit in the Tail/Tag Circuit. The
Tail/Tag LED will blink, the Open Circuit Indicator will ash and the MUTT®will beep.
NOTE: Open Circuit Indicator will only illuminate during circuit selection.
CROSSED CIRCUITS
The MUTT®indicates that two or more circuits are back feeding or crossed. This
can be a symptom of two wires in the same harness wearing through their insulated
coating and connecting.
1. When a crossed circuit is identied, the selected circuit LED will illuminate steadily
and the circuit it is crossed with will ash. The MUTT®will also provide an audible
alert (beep).
Example: The MUTT®detects that the Tail/Tag and Elec. Brake are crossed while the
Tail/Tag Circuit is selected. The Tail/Tag LED will illuminate, the Elec. Brake LED will
ash and the MUTT®will beep.
Example: Open Circuit in Tail/Tag Light
Example: Crossed Circuit in Tail/Tag and Elec. Brake Lights

17
NOTE: In some cases, a crossed circuit may be a normal function of advanced
diagnostic testing, such as with certain ABS systems.
SHORT/OVERLOADED CIRCUIT
Short circuits or overloads can occur when a positive, hot wire touches ground.
They can also occur due to faulty lights or connectors.
1. If a short or overloaded circuit is suspected, the MUTT®will instantly stop
powering the circuit.
2. The Overload Warning Indicator will then ash, along with the selected circuit’s
LED. The ammeter needle will also max out and return to 0.
3. The MUTT®will now automatically enter Pulsar®mode. During Pulsar®mode,
the MUTT®will attempt to reapply power to the faulty circuit every 3 seconds for
an indenite period of time. After power is applied, if a short is still present, steps
1-3 will automatically repeat.
Example: The MUTT®detects a short in the Tail/Tag Light Circuit. The Tail/Tag LED
and Overload Warning Indicator will ash and a warning beep will sound. The MUTT®
will now enter Pulsar®mode.
NOTE: Pulsar® mode can be a useful troubleshooting tool for nding dead and
intermittent shorts.
Example: Short Circuit in the Tail/Tag Light

18
7.4 ACTIVATING HAZARD LIGHTS
The four-way ashers on the vehicle can be activated with the 3-Button Remote
Control and the 12-Button Remote Control.
3-Button Remote Control
1. To activate, press and hold the Down Arrow button for 5 seconds.
12-Button Remote Control
1. To activate, press and hold Hazards Button.
Press and Hold DOWN ARROW to Activate
Press and Hold HAZARDS to Activate

19
7.5 ALL CIRCUITS ON (OVERRIDE) MODE
All Circuits On Mode will engage all electrical circuits at the same time. While short
circuit sensing is operational in this mode, if a short circuit is found, the MUTT®will
not be able to identify which circuit is the cause of the short. Open and crossed
circuits sensing is not operational in this mode.
On trailers using incandescent bulbs, All Circuits On Mode will typically result in an
overload because the amperage draw will exceed the maximum of 20 amps.
All Circuits On Mode can be accessed manually or by remote control.
