OEMTOOLS Relay Circuit Tester is capable of testing an entire circuit from the battery to the questionable component, not just the relay. Any technician or mechanic will love the fact that this circuit tester instantly pinpoints the problem within a tested circuit. Since the relay circuit tester can jump the relay, you can use it as a remote control starter during engine work like compression testing, distributor or camshaft adjusting, or run the compressor during an A/C charge.
