GENERAL CHARGER USE
RISK OF ELECTRIC SHOCK AND FIRE
• Before connecting charger to unit, 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 cord or plug 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 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 charger.
• 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 for
charging dry cell batteries.
• Electric shock or fi re can cause injury.
RISK OF ENTANGLEMENT
• Keep yourself, clothing and battery charger leads clear of moving parts such as
fan blades, pulleys, hood and doors.
• Moving parts can cause injury.
RISK OF BURNS
• Batteries can produce short circuit current high enough to weld jewelry such
as rings, bracelets and watches. You must remove them before working near
batteries.
• Short circuits can cause injury.
DO NOT
Plug Directly Into
AC Wall Outlet

CROSSED CIRCUITS
The MUTT
®
indicates that two or more circuits are back feeding or crossed. This
can be a symptom of two wires in the same harness wearing through their insulated
coating and connecting.
1. When a crossed circuit is identifi ed, the selected circuit LED will illuminate steadily
and the circuit it is crossed with will fl ash. The MUTT
®
will also provide an audible
alert (beep).
Example: The MUTT
®
detects that the Tail/Tag and Electric Brake are crossed while
the Tail/Tag Circuit is selected. The Tail/Tag LED will illuminate, the Electric Brake LED
will fl ash and the MUTT
®
will beep.
NOTE: In some cases, a crossed circuit may be a normal function of advanced
diagnostic testing, such as with certain ABS systems.
SHORT/OVERLOADED CIRCUIT
Short circuits or overloads can occur when a positive, hot wire touches ground.
They can also occur due to faulty lights or connectors.
1. If a short or overloaded circuit is suspected, the MUTT
®
will instantly stop
powering the circuit.
2. The Overload Warning Indicator will then fl ash, along with the selected circuit’s
LED. The ammeter needle will also max out and return to 0.
3. The MUTT
®
will now automatically enter Pulsar Mode
®
. During Pulsar Mode
®
, the
MUTT
®
will attempt to reapply power to the faulty circuit every three seconds for
an indefi nite period of time. After power is applied, if a short is still present, steps
1-3 will automatically repeat.
Example: The MUTT
®
detects a short in the Tail/Tag Light Circuit. The Tail/Tag LED
and Overload Warning Indicator will fl ash and a warning beep will sound. The MUTT
®
will now enter Pulsar Mode
®
.
NOTE: Pulsar Mode
®
can be a useful troubleshooting tool for fi nding dead and
intermittent shorts.
Example: Crossed Circuit in Tail/Tag and Elec. Brake Lights
Example: Short Circuit in the Tail/Tag Light
