Electrical Problem?

So i let my uncle borrow my car for a few days and the battery died on him (Bad Alternator) but i returned the battery and got a brandnew one from CT. Car Starts and runs but gauges, Windows, Ac/Heat, Defrosters, Wipers, Radio, and interior Lights, Brake lights, Dont seem to work. My uncle took the car for a spin
and when he dumped the clutch in second the car jerked and everything came on but after we turned the car off nothing would turn back on.

I dont think its fuses because everything still seems to work just wont turn on.

Check the harness that runs under the driver’s side fender, especially if it’s lowered. Also check it across the front where it runs past the rad. I had a wear spot there as well, so when I fixed it under the fender it was still causing me issues.

That’s definitely what it sounds like to me. Check grounds as well.

Alt fuse. I am currently haveing the same problem. It’s that if when you start the car, nothing works, but when you rev it everything starts to work.
