TYPICAL TRAILER WIRING
NOTE: The standard wiring pictured in fi g. 4 is viewed from the front of the connector.
Not all trailers/vehicles are wired to this standard. The use of an electrical circuit tester is
necessary to ensure proper match of a vehicle’s wiring to a trailer’s wiring. On the 6-way
plugs, the 12V wire and electric brake wire may be reversed on some trailers (particularly
horse trailers).
1. Plug the 3-way adapter into the 7-way socket on the Ranger MUTT
®
.
2. Be sure to push fi rmly until the key is down far enough for the fl ap to lock in behind it.
3. Plug the trailer into the proper terminal on the 3-way adapter. NOTE: The 5 pin
connector also works for 4 pin trailer sockets.
4. To begin testing the trailer, turn the control knob to the desired circuit (as indicated on
the faceplate).
5. Once the knob is turned to the selected circuit, power is being sent to the
corresponding wire on the trailer.
6. Follow the 7-way spade pin testing procedure (pg. 7) section for further information.

THE FOLLOWING SAFETY ALERT SYMBOLS ARE
USED IN THIS MANUAL.
SYMBOL 1: Potential burn hazard. Sparks from electrical shorts can ignite fl ammable
liquids such as fuel or oil. Heat from electrical overloads can cause fi re hazards.
SYMBOL 2: Potential electrical hazard. Batteries have enough electrical energy potential
to ignite fl ammable liquids such as fuel or oil. Wire overloads can cause electrical failures.
Shock hazard exists.
SYMBOL 3: Potential explosive air hazard. Pneumatic pressures used with this equipment
can cause explosive failures on damaged equipment.
SYMBOL 4: Potential eye hazard. Wear OSHA approved safety glasses. Battery acid and
high air pressures create hazardous situations for eyes.
SYMBOL 5: Potential chemical burn hazard. Wear protective gloves. Battery acid is cor-
rosive and can cause skin damage.
SYMBOL 6: Potential electrical hazard. Electrical energy can cause heat and burn haz-
ards.
SYMBOL 7: Potential fi re hazard. Use caution with fl ammable liquids such as fuel and oil.
Electrical shorts can ignite fl ammable liquids and wiring.
SYMBOL 8: Important information is stated.
BATTERY GASES, TESTER PREPARATION AND
TESTER/CHARGER LOCATION
RISK OF EXPLOSION
• Gases produced by a battery are highly explosive.
• Wear safety goggles and protective clothing, both users
and bystanders.
• Use in an area having at least four air changes per hour.
• Read, understand and follow all instructions for charger,
battery, vehicle and any equipment used near battery and charger.
• Do not smoke, strike a match, place metal tools on the battery or cause a spark in the
vicinity of the battery. When removing battery cables, remove the ground cable fi rst.
• Clean terminals before charging battery. During cleaning, keep corrosive particles from
eyes, nose and mouth. Use baking soda and water to neutralize acid and help eliminate
airborne corrosion.
• Never allow the clamps on the charger cables to touch each other.
• Do not expose the tester or charger to rain, snow or wet conditions.
• Do not allow battery gases or acid to contact the Ranger MUTT
®
cabinet. Do not place
the charger directly above or below the battery.
• Fill the battery to the level specifi ed by battery manufacturer using distilled water.
• Do not remove cell caps while charging per manufacturer’s instructions.
• Make sure tester cable clamps make tight connections.
• Battery explosion can cause injury.
