SET-UP
• Place the tester on a at, level surface.
• Chock trailer wheels to avoid rolling.
The Ranger MUTT
®
allows for the testing of trailer electrical systems without the
need of 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
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 that you
have a solid connection in the 7-way socket.
