The CAL 76 Relay Circuit Pro can test 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 will identify at the push of a button if a wire a part or a relay is defective without the use of a multi-meter.
For additional testing use the ports on the CAL 76 to connect to other diagnostic tools. Since the CAL 76 can jump, use it as a remote control starter in engine work like compression testing distributor or cam shaft adjusting or to run the compressor during an A-C charge.
Works with both 12 and 24 volt systems.
