Sorry to start one i'm just a lil stumped 88 na Vert

car wont start, aux works radio, lights i go to turn it on i just hear a click, and everything shuts off door lights off nothing, i jiggle the positive wire cable( which is on there pretty tight to begin with) and power is back on so i need opinion the car worked fine less the 6 hours ago

 

Check battery charge.

 

no took it to autozone and said it was good, so i'm thinking wiring or bad alternator

 

Jiggle and it works? Isn't that obvious enough to tell ya what to look for?

 

There are two cables connected to the positive battery terminal. Besides the one that goes to the starter the other Black cable goes to the engine fuse box. Make sure this connection is good not just at the battery, but also the fuse box as well.
