Worth every penny
The circuit probe tester works great. I've already used it multiple times & I'm glad I have the option to apply power to the circuit. One instance I was told the heater fan motor was bad. I disconnected it and applied power to the fan without removing it applied power and it worked it ended being corrosion in the contact. It's saves time and money
