QUICK REFERENCE GUIDE
OPERATION AND TESTING
ELECTRICAL TESTING
1. CABLE TESTING: It is always recommended that you use the cable tester to
verify that the MUTT ® ’s 7-way round pin cable is in proper working order before
trailer testing. To perform the Cable Test, insert both ends of the 7-way pin cable
one in each receptacle on the MUTT
® ’s side. Once the cable is installed, turn the
MUTT ® on to verify the continuity between both ends of the cable. Look for the
solid green light verifying Ground Integrity and note if there are any green circuit
LEDs blinking. Note that each circuit is tested upon start up as well as ground
fault check. Solid LEDs mean good connection and blinking LEDs indicate an
open circuit or poor continuity. The cable tester can also be used to inspect all
trailer cables.
2. GROUND INTEGRITY: When the MUTT ® is first turned on, Ground Integrity and
Open Circuit checks are being performed. The green lights around the Control
Knob will blink and disappear one at a time until only the Ground Integrity light
remains solid green. When all the lights blink, it indicates a poor cable connection
or bad ground. Individual blinking lights indicate an open circuit. (Refer to
pg. 11, K)
3. CIRCUIT PROBLEM INDICATION: As you turn the MUTT ® control knob to test
each circuit, a steady green light verifies a properly working circuit. Refer to the
three red LEDs to the left of the control knob for circuit problem indication. These
LEDs will blink and the MUTT
® will sound if there is a problem.
4. LOW DRAW LED TRAILERS: The MUTT ® will identify any circuit drawing less
than 100 mA as an open circuit. The trailer must have a minimum of two standard
LED pods on each circuit. ABS circuits using ABS computers are typically within
the threshold and do not require additional load.
5. CIRCUIT SELECTION: Circuits can be selected by pressing the control knob
for Auto Cycle mode, manually turning the control knob, or by using the remote
control.
6. ALL CIRCUITS ON: All circuits can be turned on at one time by pressing/holding
the large remote button for five seconds. To cancel, press and release the large
button on the remote.
AIR BRAKE TESTING
(See detailed instructions on page 19-21)
1. AIR BRAKE TESTING: Main power must be on.
2. LEAK DOWN TEST: To conduct leak down test on the Service and Emergency
line air circuits, open the Emergency Side ball valve to charge the circuit with air,
then close ball valve and note any pressure drop. Any pressure drop on the gauge
is an indication of a leak in the circuit. Repeat leak down test on the Service Side.
3. ACTUATE BRAKES: Push the selector switch to left, then by using the remote
control and in real time, actuate the brake servos. This feature allows you to see
the slacker adjustments and the push rod travel in real time.
