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 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 3 seconds for an
indenite 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 Clearance Light Circuit. The Clearance
LED and Overload Warning Indicator will ash and a warning beep will sound. The
MUTT® will now enter Pulsar Mode®.
NOTE: Pulsar Mode® can be a useful troubleshooting tool for nding dead and
intermittent shorts.
Example: Short Circuit in the Clearance Light
