Hey guys

Let me know what u think of this tool ive come up with.
Its a safty jumper! It would have one clip one each side of wire, in the middle of the wire it would have a silver dollar size conponit wich has a digital screen to measure voltages, the kick is if u were to jump the wrong wires say like r and common it would trip setting off a red led light saving the fuse or transformer ect, then u would push the reset button and try it again,
I think this would be usefull for new guys as well as a vet. After the first trip it would pay for itself as well as save u time and money. What do u guys think let me know
