CABLE TESTING
The MUTT ® has a special cable feature to test 7 round pin cables for continuity. The
cable testing feature can be used to test a tractor’s cable or the supplied MUTT ® cable.
It is recommended that all cables be tested prior to MUTT ® operation.
TEST PROCEDURE
PRIOR TO CABLE TESTING:
To avoid erroneous fault, be certain the 7 pins in each plug are clean
and spread to the proper size.
• Insert each end of the cable into both side connectors on the MUTT ® .
Be sure to push the cable ends in firmly until they reach the bottom of the
connector.
• Turn main power switch ON.
• Once the power is turned ON, the green lights around the Control Knob will
blink and disappear one at a time until only the Ground Integrity light remains
solid green. Once the initial check has been performed, poor cable conditions
will be shown by a blinking light for the problem circuit.
• If the cable has an open circuit or continuity problem, the corresponding circuit
flashes repeatedly.
• Further testing can be performed by selecting each circuit individually via the
Control Knob or Remote. When an open circuit is detected, the LED for the
circuit will flash and an audible alert will be heard.
NOTE: Always check the MUTT ® connector pins at the side of the MUTT ® for proper ex-
pansion. Over time the pins may bend in slightly resulting in a poor connection between
the connector and the cable ends. A flat head screwdriver can be used to expand the
pins until the a tight connection is made.
