WORK SAFE!!
Look for test probes that expose just 1/8 inch or less of the metal tips. I just bought a Craftsman hook-type current DMV. It had two leads with removable covers for the probes that just exposed the pointy part. The covers came off to give you the ability to put the probe into a narrow hole and to screw on the accessory alligator clip(s). [20% off vets discount, it never hurts to ask!]
