No electrical power to the switch

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Reversing the battery is like shocking your Capri with a lightning bolt—things get fried fast. Likely culprits include a blown main fuse or fusible link, designed to sacrifice themselves to save the rest of the system. Check under the hood near the battery or in the fuse box for a melted link or busted main fuse. If those are fine, you may have roasted a relay or damaged the alternator. Let’s hope the electrical gremlins didn’t party too hard. If you need any further advice or want help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554.
