Red channel wheel speed sen-
sor wiring S1A has an Open or
Short circuit.
Indicates a wheel speed sensor or its
wiring has short or open circuit. Discon-
nect the relevant sensor and measure
the resistance between the two pins in
the sensor connector housing.
If sensor extensions are used, verify
extension continuity and connections.
Replace sensor and/or extension cable.
The Ohm meter reading for the sensor
or sensor and extension cable should be
between 980 and 2350 Ohm (.98K and
2.35K Ohm) If not, replace sensor and/
or extension cable.

Red channel speed sensor S1A
has low sensor output.
Sensor or spring clip is worn or not properly
adjusted, wiring open or short circuit, wheel
bearing not properly adjusted (these faults
will only occur at speeds of greater than 6
mph). Measure the AC voltage at the sensor
in question while rotating the wheel at a rate
of about one revolution every two seconds.
The output should be at least 200 millivolts
(0.2V AC). If this is not the case, push in the
sensor until it touches the exciter and rotate
the wheel again. If this doesn’t correct the
problem, then the sensor and the sensor
block clip should be replaced.
If sensor extensions are used, verify
extension continuity and connections.
Replace sensor and/or sensor cable.
Inspect exciter teeth for minor damage or
teeth fi lled with debris. Verify all exciters have
the same number of teeth.
Verify sensor and valve wiring/plumbing is
correct.

PART 4: SET-UP
4.1 CHOOSING A BATTERY
The MUTT® is a 12/24V DC device. Attempting to
power your MUTT
®
with anything other than a 12 or 24
volt DC power source will destroy the internal circuitry
and void your warranty.
Manufacturer’s Suggested Battery: Group 31. MUTT
® will auto detect 12 or 24 volts.
If 24 volts is required, two smaller 12 volt batteries can be used, but they must be
wired in series.
• Battery Voltage: 12/24V DC
• Battery Type: Lead Acid
• Battery Compartment Dimensions:
14" W x 15 ½ " H x 13" D.
• Battery Protection: Inline 30A fuse
for overcharge.
• Battery must be clean and leak free.
• Identify battery polarity.
• Attach ring terminal with red heat shrink to
positive (+) side and ring terminal with black
heat shrink to negative (-) side. Also see
warning indicators on pg. 4. Connections
must only be made to clean terminal rings.
• Any loose or corroded connectors may cause
misdiagnosis or result in erroneous readings.
• Use fully charged battery.
4.2 LIFTING THE UNIT
The MUTT® has three handles for use in maneuvering the unit. It should be noted
that these handles are not intended to be used as lift points. If the unit needs to be
lifted, you MUST use two people and lift from the bottom of the unit. DO NOT use
just the handles for lifting the unit.
