Cal-Van Tools Relay Circuit Pro Testers

Cal-Van Tools Relay Circuit Pro testers can examine an entire circuit, from the battery to the component in question, as well as determining if the relay itself is functioning properly. Relay Circuit Pro units give technicians the ability to instantly determine the problem within a tested circuit. They will identify, at the push of a button, if a wire, a part, or a relay is defective without the use of a multimeter. If the technician wishes to gain more information about the problem, the tool also features easily accessible ports for use with other diagnostic tools. And since the testers can jump the relay, the technician can use them as remote control starters in engine work, like compression testing a distributor, camshaft adjusting, or to run the compressor during an A/C charge. Cal-Van patent-pending Relay Circuit Pro testers will work with both 12 V and 24 V systems, and each of them include 6 popular relay leads and a universal relay lead packed inside blow-molded cases with high-density foam inserts.
