calculations, as well as digital voltage and amperage draw readout. The Alpha MUTT®will detect poor
grounds, open circuits, crossed circuits, short circuits, and also features Pulsar®mode which aides in
troubleshooting intermittent and dead shorts. The ABS diagnostics can be utilized to read andclear codes
and display troubleshooting information on a trailer via the 7-way connector. Those readings are
displayed on the face panel as well as through the tablet app.

1.2 Important Safety Information
It is important to read, understand and follow all safety messages and instructions printed in this
manual and on the equipment before operating. If safety information is not heeded, serious injury
or death to the operator or bystanders may occur.
Danger
Indicates a hazardous situation, if not avoided, will result in death or serious injury. The possible hazards
are shown in the adjoining symbols or explained in the text.
Warning
Indicates a hazardous situation, if not avoided, could result in death or serious injury. The possible
hazards are shown in the adjoining symbols or explained in the text.
Caution
Indicates a hazardous situation, if not avoided, may result in minor or major injury. The possible hazards
are shown in the adjoining symbols or explained in the text.
The following safety alert symbols are used in this manual.
Symbol 1: Potential burn hazard. Sparks from electrical shorts can ignite flammable liquids such as
fuel or oil. Heat from electrical overloads can cause fire hazards.
Symbol 2: Potential electrical hazard. Batteries have enough electrical energy potential to ignite
flammable liquids such as fuel or oil. Wire overloads can cause electrical failures. Shock hazard exists.
Symbol 3: Potential explosive air hazard. Pneumatic pressures used with this equipment can cause
explosive failures on damaged equipment.
Symbol 4: Potential eye hazard. Wear OSHA approved safety glasses. Battery acid and high air
pressures create hazardous situations for eyes.
Symbol 5: Potential chemical burn hazard. Wear protective gloves. Battery acid is corrosive and can
cause skin damage.
Symbol 6: Potential electrical hazard. Electrical energy can cause heat and burn hazards.
Symbol 7: Potential fire hazard. Use caution with flammable liquids such as fuel and oil. Electrical
shorts can ignite flammable liquids and wiring.
Symbol 8: Important information is stated.
1.3 Battery Gases, Tester Preparation and Tester/Charger Location
Risk of Explosion
•Gases produced by a battery are highly explosive.
Battery explosions can cause injury.
•Wear safety goggles and protective clothing, both users
and bystanders.
•Use in an area having at least four air changes per hour.
•Read, understand and follow all instructions for charger, battery, vehicle and any equipment used
near battery and charger.

PART 1: INTRODUCTION AND SET-UP 1-3
•Do not smoke, strike a match, place metal tools on battery or cause a spark in the vicinity of the
battery. When removing battery cables, remove the ground cable first.
•Clean terminals before charging battery. Keep corrosive particles from eyes, nose and mouth.
Use baking soda and water to neutralize acid and help eliminate airborne corrosion.
•Never allow clamps on charger cables to touch each other.
•Do not expose tester or charger to rain, snow or wet conditions.
•Do not allow battery gases or acid to contact MUTT®cabinet. Do not place charger directly above
or below battery.
•Fill battery to level specified by battery manufacturer using distilled water.
•Do not remove cell caps while charging per manufacturer instructions.
•Make sure tester cable clamps make tight connections.
1.4 General Charger Use
Risk of Electric Shock and Fire
•Before connecting charger cable to tester,
make sure controls are set to OFF.
•Do not remove or bypass the grounding pin.
•Do not operate charger with damaged cord or plug. Replace immediately if damage occurs.
•Position power cord and charger cables away from the hood, doors and hot or moving engine
parts where they could be damaged.
•Unplug power cord by grasping and pulling on the plug, rather than the cord, when disconnecting
charger from outlet.
•Charger power cord uses an equipment-grounding conductor and a grounding plug. Plug only
into a 120V AC outlet that is correctly installed and grounded in accordance with all ordinances
and local codes.
•Unplug power cord from outlet before cleaning or maintaining tester and charger. Turning off
controls does not reduce the risk of electric shock.
•Do not operate charger after a sharp impact, drop or any other damage. Do not disassemble.
•Use only recommended attachments.
•Do not charge a frozen battery. Do not overcharge a battery.
•Use charger only on lead-acid automotive batteries. Do not use charger to charge dry-cell
batteries.
•Electric shock or fire can cause injury.
Risk of Entanglement
•Keep yourself, clothing and battery charger leads clear of moving parts such as fan blades,
pulleys, doors and hood. Moving parts can cause injury.
Risk of Burns
•Batteries can produce a short circuit current that is high enough to weld jewelry such as rings,
bracelets and watches. You must remove them before working near batteries.
•Short circuits can cause injury.

1.9 Battery Requirements
The Alpha MUTT®is a 12/24V DC device. Attempting to power the
MUTT®with anything other than a 12- or 24-volt DC power source
will destroy the internal circuitry and void the warranty.
IPA®suggests using two Group 31 batteries for all Shop Models.
DO NOT use 24 volts on 12-volt circuits.
•Battery Voltage: 12/24V DC
•Battery Type: Lead Acid
•Battery Compartment Dimensions: 14" W x 15.5" 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.
Connections must only be made to clean terminal rings.
•Any loose or corroded connectors may cause erroneous
readings and result in misdiagnosis.
•Use fully charged batteries.
