Circuit Tester - CT8002- by GTC

Back in 1989, General Technologies unveiled a new, computer safe, all solid state electronics circuit tester . Unlike regular test lights, this high-impedance circuit tester is safe to use around automotive computers, electronics, ecm’s, sensors and air bags. It requires no wire or clip connector to ground. Rugged, built to last and simple to use on automobiles, trucks, trailers, RV’s, motorcycles, boats and any DC powered circuit from 3 to 28 volts. The tester allows users to run a test in less time that it takes to set-up a regular test light on a suitable ground.
