Product Manual

NOTE: The SMART MUTT® uses an advanced form of current sensing through-

out all circuits at all times. This may cause dim lighting of some high ecient

LEDs in unselected circuits. The Crossed Circuit Indicator functions in the

Small Trailer LED mode, and eliminates a possible misdiagnosis from the

current sensing of the MUTT®. Brake light selection does not show a crossed

circuit to a turn signal.

NOTICE!

When using the SMART MUTT® on trailers with a few LED lights on each cir-

cuit, you may notice a “ghosting” eect or dim lighting of circuits not selected

by the SMART MUTT®. This “ghosting” is normal and should be ignored. When

power is applied to a selected circuit, the lights illuminate much brighter and

can clearly be identied as the active circuit. The “ghosting” eect is caused

by the circuit sensing mode which constantly scans all of the trailer’s circuits

during the testing phase to instantly identify any faults. In some low current

draw applications, a low current alarm may sound on the SMART MUTT®. This

alarm can be bypassed.

ALL CIRCUITS ON (OVERRIDE)

Turns all circuits on (maximum load amount 20 AMPS total—ideal for

LED trailers.)

All Circuits On Mode can be accessed by the control knob or remote control:

• Hold down Control Knob for 10 seconds. Listen for the second beep and

release Control Knob.

• Hold down large button on remote for 5 seconds. On trailers using incan-

descent bulbs, all circuits on will typically result in an “Overload” because

the amperage draw will exceed the allowed 20 AMP maximum. NOTE:

Short Circuit sensing is operational in this mode. When Short Circuit is

found in this mode, the MUTT® will not be able to identify which circuit is

the cause of the short. Open Circuit sensing is not operational.

• To cancel “All Circuits On” mode, turn selector knob or press and release

the large remote button.
