PART 7: ELECTRICAL/LIGHTING TESTING
Complete the pretesting checklist prior to all testing procedures.
The MUTT
®
is microprocessor controlled and features a special diagnostic fi rmware,
designed to seamlessly integrate with your preferred methods of testing. The MUTT
®
will power the selected electrical circuits and instantly alert you to any signs of a faulty
condition. To properly utilize the diagnostic features, a complete scan of the
trailer’s electrical system should be performed at the front of the trailer using the
MUTT
®
prior to a walk-around inspection. If any wiring faults are present, the MUTT
®
will blink or sound, alerting you to the issue. Only a one-time, walk-around/visual
inspection is needed to confi rm that each individual light bulb is properly illuminating.
NOTE: Some advanced functions may not be listed on the face panel, so it’s
important to read the manual in its entirety to ensure that you are getting the full use
of this diagnostic system.
7.1 SELECTING A CIRCUIT
Circuits can be selected for testing manually, via remote control or by initiating Auto
Cycle Mode.
OPERATING WITH MANUAL CONTROL
1. Turn the control knob to select a circuit. The control
knob is automatically set to Ground Integrity when
power is turned on.
OPERATING WITH THE REMOTE CONTROL
1. Press and release the UP ARROW to select the next
circuit in a clockwise rotation.
2. Press and release the DOWN ARROW to select the next
circuit in a counterclockwise rotation.
AUTO CYCLE MODE
Auto Cycle Mode automatically tests one circuit at a time
in a clockwise rotation.
1. Press and release the control knob. The Auto Cycle
Indicator should illuminate.
2. A fi ve second delay commences before power is
automatically applied to the fi rst circuit.
3. Circuits are automatically tested one at a time in a clockwise rotation, starting
from the Ground Integrity Indicator.
4. To cancel Auto Cycle Mode, momentarily press and release or turn the control knob.
NOTE: Auto Cycle Mode does not work when Brake Light Circuits are selected.
