Every time I turn the key, the engine back L fuse blows. I checked the alternator and all other fuses and I do not know what else to look for in the wiring. Does anyone have any idea of how to fix this?

Hello, I think you are referring to the engine back up L fuse, so you have a short to ground some where. Is there a number for the fuse on the fuse box cover?

Also, try unplugging the alternator and turn the key on with a new fuse in, if it blows with the key on then the alternator has a short to ground. Just a quick try to eliminate the alternator as the problem.
