2003 GMC Yukon Problem

[Fless]

Does anyone know which fuse it could be if thats true

The one that's blown. [sorry, couldn't resist a great straight line!]

I believe its one of the fuses that you cant see the inside of. The ones under the hood. Any suggestions what to do would be great. Ty

Get a cheap test light and check fuses. Or a DVM if you have one. Either way is easier than visually checking them.

I purchase a test light and hooked up the ground to the negative battery terminal. I had power to the battery. No power to the alternator nut on back. No power to the red box below the alternator that the wire fron battery and wire from alternator meet.Any suggestions would be great. Ty

Battery cable probably. Run a jumper and check, but don’t try to start it that way.
Edit: check both positive and ground, they’re equally important.

If the cable holds true it’s astounding how many, and how many different, problems they can cause.

Im sorry I never got back to you all. I ended up finding the problem. My wire going to the starter was corroded and I cleaned it up and every thing so far is perfect. Ty to all for the great support
