Your multimeter is a versatile tool. But for certain diagnostics, you need an oscilloscope to get a closer look at a vehicle’s electrical systems.

Working on some battery cables or custom ground straps? Your crimped connection needs to be totally reliable, and with a proper tool like Dorman’s 90707 heavy lug crimper, you’ll get secure and consistent results. This crimper also happens to work well when replacing the ground cable on a welder.
