Review on OEM Tools 25886 Circuit Tester: Fuse & Circuit Short Checker with Glowing Light, Simple Design, Testing Probe & Heavy Duty Ground Clamp by Jeffrey Nunes

When I checked the fuses in my fuse box with the test lamp, it did not light up at first. I tested it on the battery and it fired. Knowing none of my types had blown, I swapped out the main wire and it worked until I switched to a new fuse. He was hit or missed whether he was working or not. I spent more time checking lighting capability than checking fuses. I will not buy again.
