PART 5: PRETESTING CHECKLIST

The pretesting checklist should always be completed prior to using the MUTT

UNIT PLACEMENT

• Place the tester on a ﬂ at, level surface.

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 ﬂ at head screwdriver can be used

to expand the pins until a tight connection is made.

TRAILER CONFIGURATION SET-UP

The 9004A Smart MUTT

is a microprocessor controlled

diagnostic trailer tester speciﬁ 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 Conﬁ guration Set-Up and is indicated by a high speed ﬂ icker-

ing of the LEDs surrounding the control knob. If left untouched after 15 seconds,

the tester will always default to a 7 spade pin conﬁ 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 Conﬁ guration Set-Up is repeated each time the

unit is powered up.

Testing 4, 5 and 6 Round Pin Type Trailer Connections

The 9004A 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 9004A 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 instructions

above for Trailer Conﬁ guration Set-Up should be used for more efﬁ cient and accu-

rate testing.
