At first, it did not work. We thought we had wired it incorrectly. We checked our wiring. Everything checked out. But no continuity through the switch. Nonetheless, we tested it again and it suddenly decided to start working. It has worked reliably since, but I don't think it is a very good switch. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Four Stars *by R***D on Reviewed in the United States on November 14, 2017* Works as intended ### ⭐ 1.0 out of 5 stars Failed - Terminals for the Alternator and Ign. *by B***E on Reviewed in the United States on May 15, 2022* Worked when I got it.
