If your car won't start and seems dead after the battery was hooked up wrong or jump started backwards, this video will show you how to fix it. This is specifically for GMC Yukon, Denali, and Yukon, as well as Chevrolet Tahoe, Suburban, and Silverado. But it will also help you fix other makes and models that use a mega fuse.

To purchase a new mega fuse or the tools I used in this video, click on one of the following links:
