Innovative Products of America Heavy Ranger MUTT Portable Trailer Light Tester with 7-Way Round Pin (SAE J560) for Commercial Tractor Trailers

Well made. Works as it should.

Works well

Bought this to test trailer function on 7 way round pin connectors and works great...

just as described

The product is poorly packaged from the manufacturer. The 7-way plug has an extended lip used to open the cover. The loose packaging allows the unit to shift around in the box and depending on how the box is handled it can break off. Another customer posted a picture of the exact damage I have. The tool itself is well put together and the quality is good. It works as designed. You’ll get a workout as you have to circle the trailer after each selection since it manually tests one circuit at a time. Keep in mind, you will have to get a battery and a 7-way cable to use this tool. A straight cable is a better option if you’re going to leave the tool on the ground while testing. Overall, including the damage, I’m happy with the purchase. I do feel like the manufacturer needs to add some foam to prevent damage but I’d definitely buy another one if need be.

These are awesome!!

So i didnt really use a conventional battery i actually hooked it up to a Bauer battery, real lightweight , its plastic and im sure if you mistreat it , it will break but its really nice. I check trailer chassis and this makes it realll easy to check

Perfecto
