QUICK START-UP GUIDE

The SMART MUTT® is designed to eliminate guesswork and the remote

control is provided to make your job easier. If something is wrong with

your trailer’s electrical system, the SMART MUTT® will make noise and

blink LEDs to lead you towards the problem.

1. CHECK 7 PIN CONNECTORS: Before operating the SMART MUTT®,

be sure the 7 round pin connections at the top of the unit is in good

condition and pins are spread to the proper width to ensure good

connections. Check both ends of the 7 round pin plug on the trailer

and cables.

2. MAINTAIN 7 PIN CONNECTORS: Dielectric grease should be used on

all connections to avoid corrosion. If a bad connection exists at the

terminal junction, you may get an erroneous reading and the MUTT®

will not work properly. Make sure that you have a solid connection in

the 7 way socket.

3. TO PROGRAM YOUR REMOTE: Turn the SMART MUTT® on while hold-

ing down the large button on the remote, then let go after 3 seconds.

Your remote is now programmed to the tester. (Up to 24 separate

remotes can be purchased and programmed to one SMART MUTT®.)

4. OPEN CIRCUIT: If at any time a circuit indicator LED (e.g. clearance or

brake lights) is steadily blinking immediately following the Ground

Integrity test, this is an indication of an Open Circuit. An Open Circuit

could be a cut wire, an improper pin connection, or the circuit is not

available (hooked up) on that trailer. Be sure to wiggle your 7 way

connectors to make sure it is not just a loose pin connection at the

socket (there is a Chassis Ground problem if all LEDs are blinking).

5. LOW DRAW LED TRAILERS: If all LEDs on your trailer are dimly lit,

please read the manual section where we discuss “ghosting” before

you assume there is a problem with the trailer or the tester.

AVOID MISDIAGNOSIS:

• Before attaching to trailer connector, make sure all sockets

and pins are clean and tight.

• Any loose or corroded connector may cause a misdiagnosis.

• Use a well-charged battery.
