ACID BURNS
• Battery acid is highly corrosive sulfuric acid.
• Wear safety goggles, both user and bystanders.
• Wear safety gloves.
• Make sure someone can hear you or is close enough to provide aid when working near
battery.
• Have plenty of fresh water and soap nearby. If battery acid contacts skin, clothing
or eyes, fl ush the exposed area with soap and water for 10 minutes before seeking
medical help.
• Do not touch eyes while working near battery.
• Battery acid can burn eyes and skin.
GENERAL CHARGER USE
RISK OF ELECTRIC SHOCK AND FIRE
• Before connecting power cord to the charger, make sure
controls are set to off.
• DC power only.
• Do not remove or bypass the grounding pin.
• Do not operate the charger with a damaged cord or plug. Replace the cord or plug
immediately.
• Position the power cord and charger cables away from the hood, doors or hot and/or
moving engine parts where they could be damaged.
• Unplug the power cord using the plug rather than the cord when disconnecting the
charger from the outlet.
• Unplug the power cord from the outlet before cleaning or maintaining the tester and
charger. Turning off the controls does not reduce this risk.
• Do not operate the charger after a sharp impact, drop or any other damage.
Do not disassemble the charger.
• Use only recommended attachments.
• Do not charge a frozen battery. Do not overcharge a battery.
• Use the charger only for lead-acid automotive batteries. Do not use the charger for
charging dry cell batteries.
• Electric shock or fi re can cause injury.
RISK OF ENTANGLEMENT
• Keep yourself, any clothing and the battery charger leads clear of moving parts such
as fan blades, pulleys, hood and doors.
• Moving parts can cause injury.
RISK OF BURNS
• Batteries can produce short circuit current high enough to weld jewelry such as rings,
bracelets and watches. You must remove them before working near batteries.
• Short circuits can cause injury.

TEST 6 ROUND AND 4/5 PIN TRAILERS
WITH 3-WAY ADAPTER
TESTING PROCEDURE
The Ranger MUTT
®
is designed to test trailers with 6 round and 4/5 pin connectors with the
use of the 3-way adapter. The faceplate on the Ranger MUTT
®
shows which functions are
supplied for each pin layout. For example: a 5 pin trailer is wired for tail lights, left turn,
brake lights, right turn and electric brakes, but not 12V aux. or backup lights. Conse-
quently, when those circuits are selected on the Ranger MUTT
®
, they do not power any-
thing on a 5 pin trailer. See fi g. 3 for the faceplate layout. The supplied adapter provides
an easy way to plug 4, 5 or 6 pin trailers into the Ranger MUTT
®
. A brief explanation of
how to get started is provided on pg. 10.
Wrong circuit is powered on trailer.
The trailer is not wired to standard
specifi cations. If possible, rewire trailer
connector to match the Ranger MUTT
®
diagrams.
Trailer electric brakes often do not make
noise when engaging. You must safely jack
up the trailer and spin the wheel while ap-
plying the brake to verify proper operation.
Another method is to check amperage load.
Most electric brakes draw approximately
1.5 amps per wheel. Check manufacturer
specifi cations for additional information.
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 will continue to pulse with power until
the issue is resolved.
Check the 7-way cable and selected circuit
for a short. The blowing of the short circuit
protection fuse is an indication of an ex-
treme short circuit condition.
I do not hear the trailer’s electric
brakes engaging.
One circuit powers two sets of lights.
The Illuminated Power Switch keeps
turning off and on again.
The fuse in my Ranger MUTT
®
keeps
blowing.
