The Heavy Ranger MUTT® is a commercial trailer light and electric brakes tester that reduces guesswork and saves time by powering each trailer electrical circuit in 7-way round pin arrangements. This allows for proper verification of wiring configuration, ground integrity, short circuit and overload conditions, along with electric brake operation and turn signal simulation. The Heavy Ranger MUTT® features a water resistant, rugged design and features an internal battery compartment and external 12V power port which can be used as a memory saver, test light supply or trickle charge input.
