This may be a stupid question, but I am trying to connect a resistor for battery home testing. The wire on the end of the risistors are short so they will not fit into the end of the clamp with a screw. I am looking for a clamp that you can tighten the rubber plastic cover so I can connect the resistor between two clamps for battery testing by clamping the positive, negative, battery leads. That way I can test batteries with a load. I want to place the short lead wire of the resistor into the handle of the clamp and tighten it.
