LETTER FROM THE PRESIDENT OF IPA®
My name is Peter Vinci and I am the president of IPA®. I would rst like to thank you for
your interest in IPA®’s product line and take this opportunity to share my commitment
to you, our products and our policies. In today’s world, we have all experienced lack of
service and consideration demonstrated by many companies after buying their products.
They say whatever they can to make the sale, and then it’s like pulling teeth to get any
service response out of them. I know this from rst hand experience and because of this, I
want to be sure that your experience with IPA®meets your expectations and our customer
service never disappoints you.
To prove my commitment to you, if for any reason you are not happy with one of our prod-
ucts, or more importantly, with the response from our customer service or any member of
the IPA®team, I invite you to contact me directly via my e-mail at [email protected], or
call me at 888-786-7899. Your satisfaction is more important to me than the sale itself. We
would not be in business for long if we didn’t make you completely happy with our prod-
ucts and service. I want IPA® to be different; to be known for its quality and service.
With that said, please take a look at our product line. You will see innovative, rst time
products that were created to help you do your job faster and better than before. I would
also like to invite you to critique our products. If you can think of a better way to make
them or changes that will make them better, then again, please contact me directly and I
will be sure to look into it. If you have an innovation and would like some feedback, give
me a call.
From all of us at IPA®, we thank you for taking the time to review our product line and wish
you and your family the very best.

with top mounted posts. (Sealed lead-acid batteries only.)
• The battery must be 12 volts DC.
• Maximum battery dimensions: 6”(L) x 4”(W) x 5.75”(H)
• Be sure to properly connect the +/- leads to the correct posts on the battery.
• Once the battery is installed, testing can begin.
TAKING CARE OF YOUR BATTERY
NOTE: Every day, a battery naturally loses its charge, little by little. Batteries are tempera-
mental and can be damaged easily. Using a battery very little and then recharging it will
short cycle the battery and hurt its overall life and output. Additionally, over-discharging
it (exceeding 80% total discharge) and then undercharging will permanently damage the
battery as well. It is not good to leave batteries in cold or hot weather. For every degree
above or below room temperature (72º F), a battery loses amp hours. Also, it is not good
to allow batteries to sit for weeks at a time without using or charging.
• To get the most life out of your battery, it is important to discharge about 30% to 50%
of its total output, then provide a full recharge.
• A 500mA battery charger has been provided with your purchase. Be sure to disconnect
the battery charger once it is fully charged. For any questions, please call 888-786-7899.
NOTE: DO NOT LEAVE THE CHARGER PLUGGED INTO A WALL OUTLET WHEN NOT
IN USE.

WARNING: NEVER OPERATE TESTER WITH BATTERY VOLTAGE LESS THAN 11.5V.
OPERATING ELECTRONIC DEVICES ON LOW VOLTAGE MAY SHORTEN LIFE OF
DEVICE AND CAUSE DAMAGE TO INTERNAL COMPONENTS. IDEAL BATTERY
VOLTAGE IS 12.0V DC TO 12.5V DC.
SET-UP
• Use the supplied battery charger or charger input no greater than 3 amps to fully charge
the internal battery of the tester. It may take up to 12 hours to charge a fully drained
battery.
• Place the tester on a at, level surface.
• Chock trailer wheels to avoid rolling.
The Ranger MUTT®allows the testing of trailer electrical systems without the need
for the tow vehicle. When used properly, the Ranger MUTT®can save hours spent
troubleshooting electrical issues.
CHECK 7-WAY PIN CONNECTORS: Before operating the Ranger MUTT®, be sure the
7-way socket on the front of the Ranger MUTT®and cable coming from the trailer are in
good condition and the pins are spread to the proper width to ensure good connections.
MAINTAIN 7-WAY PIN CONNECTORS: Dielectric grease should be used on all connec-
tions 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 that you have a
solid connection in the 7-way socket.

OPERATING INSTRUCTIONS
7-WAY ROUND PIN TESTING PROCEDURE
1. Install a fully charged 12V DC battery into your Ranger MUTT®.
2. Plug the trailer’s 7-way round pin cable into the front of the Ranger MUTT®. Be sure to
push rmly until the ap locks in behind it.
3. To begin testing your trailer, turn the power switch to the “On” position. The power
switch will illuminate. Turn the control knob to the desired circuit.
4. The Ranger MUTT® will send up to 10A @ 12V DC to the selected circuit, e.g., turn
signals, brake lights, etc. Perform a visual inspection by walking around the trailer to
verify proper lights are illuminated.
5. Step 4 should be repeated for all lighting circuits.
WARNING: LEFT TURN AND RIGHT TURN SIGNALS FLASHING TOO QUICKLY OR
TOO SLOWLY ARE AN INDICATION OF LOW BATTERY VOLTAGE. STOP AND CHARGE
BATTERY IMMEDIATELY TO PREVENT DAMAGE TO TURN SIGNAL FLASHERS.
SHORT CIRCUIT AND OVERLOAD TESTING
SHORT CIRCUIT: When a positive power source (12V +) is directly connected to, or
touching the negative terminal or ground connection, wire insulation can wear through
due to vibration. Exposed copper wire can make contact with the metal trailer frame
resulting in a short circuit and a blown fuse in the vehicle.
OVERLOAD: When the load (lights and/or electric brakes) attempts to draw more current
(amps) than the circuit was designed to handle, it often results in blown fuses.
SUMMARY: The Ranger MUTT® is capable of providing up to 10 amps of current to
a selected circuit. It is equipped with an internal, auto-resetting fuse, which is designed to
remove power to the selected circuit when the load exceeds 10 amps in overload condi-
tion. Once power is removed, the circuit breaker requires a 30-second cooldown cycle
until power can be reapplied. If the source of the excessive current draw, i.e., the overload
condition, is still present, the circuit breaker will immediately remove power once again.
This process will be repeated until the source of the excessive current draw is removed.
Most trailers should not exceed 10 amps per circuit when wired properly. You should
check the specied current draw for each light bulb or LED on the trailer circuit to deter-
mine whether it is an overload condition, short circuit condition or faulty equipment, e.g.,
electric brakes, lights, harnesses, etc.
NOTE: The auto-resetting fuse used in the Ranger MUTT®is thermally activated and
requires a short cooldown time between uses. The more often it is tripped, the longer
the required cooldown time before it will become active again.

TROUBLESHOOTING
The Ranger MUTT® is an analog trailer tester designed to help conrm trailer wiring con-
guration, proper amperage draw, functioning lights, electric brake operation and proper
ground connections. Keep in mind that many electrical problems are the direct result of a
bad ground connection. By maintaining tight, clean and sealed ground connections, you
can eliminate guesswork and improper diagnosis. We also provide the industry’s standard
wiring diagrams to help you with trailer repairs. The Ranger MUTT®is wired to meet the
accepted standard wiring congurations for the industry. Trailers which are improperly
wired or wired to “personal” specications may render the Ranger MUTT®less effective.
Ranger MUTT®does not turn on. Verify that the power switch is illuminated.
Check battery connections and charge the
battery if needed.
First verify that the Ranger MUTT®power
stays on when power is applied to the
trailer. A low battery will power the Ranger
MUTT®, but when power is sent to the
trailer, the load may cause the Ranger
MUTT®to shut down. Check for faulty op-
erating trailer lights, wiring, ground, battery
polarity, etc. Ensure 7-way cable is all the
way in on the trailer and tester. Ensure that
pins are spread.
The trailer is not wired to standard speci-
cations. If possible, rewire trailer connector
to match the Ranger MUTT®diagrams.
The trailer has crossed wires, or one termi-
nal has two wires connected at the pin.
Check battery connection and voltage. The
Ranger MUTT®’s auto-resetting fuse trips in
overload and short circuit conditions. The
Ranger MUTT®is designed for a maximum
output of 10 amps DC @ 12 volts. If a trailer
circuit exceeds this draw or there is a short
circuit, the Ranger MUTT®’s auto-resetting
fuse breaker will continue to pulse with
power until the issue is resolved.
Check the 7-way cable and selected circuit
for a short. The tripping of the short circuit
protection auto-resetting fuse is an indica-
tion of an extreme short circuit condition.
PROBLEM POSSIBLE CAUSE
Ranger MUTT®is on, but trailer lights do
not light up.
Wrong circuit is powered on trailer.
One circuit powers two sets of lights.
The Illuminated Power Switch keeps
turning off and on again.
The Auto-Resetting Fuse in my Ranger
MUTT®keeps tripping.
