For sale is my relay test kit from Mac Tools. I'm cleaning out my toolbox to make room for other tools. To buy brand new is $344.99 plus tax. It's not exactly like what you can buy today. The makers have added stuff since I bought mine. It has the jumpers, relay adapters, and I've added circuit breakers for testing the circuit with controlled power. Asking $150. This tool will also be paired with a relay circuit diagnostic tool. Message here on nextech.
