I purchased the SUPCO "Universal ECM Tester", but I am not sure where attach the two red and black "alligator clips" in order to power the ECM Tester. I've read that it needs 24 volts. My hvac model # is amvc80905cx. Can anyone help me understand where to attach the two alligator clips on my HVAC in order to power the ECM tester?
