Nothing electrical works on my car what's wrong?

[suninthyhands532]

My car was working fine then all of a sudden nothing electrical worked. Power windows, Hazard lights nor headlights would work without key in ignition. I checked all fuses the ones under dash and Hood. What else could be the problem?

The main battery cable may be corroded and not letting any power through, but it "looks" fine.

The main power cable into your fuse box could similarly be damaged.

Bad ground cables can make it impossible for anything to work.

There's a start for you.
