Hey guys! Really need help! So my tl type s 07 lost complete power even after i just turned it off and tried turning it on 5 mins later, so i jumped it and it was good, so i went to autoparts store and they tested me battery and the battery tested out good, later kept running more tests and it seems like when i have my headlights, ac and radio on the alternator is bad, but when i have no accesories like no lights on no radio etc, the alternator is good, also he said the starter is going bad. Last two weeks ago my car shut off on me completly while in motion and it turned back on after 5 mins. Like does anyone know the problem or anything??

 

I recommend cleaning your battery terminals if you haven't already.

 

Sounds like you alternator is going out if you're saying if things are on (aka have a load), you're having issues.. replace your alternator?

Also check all your grounds and make sure they aren't loose and are clean/making good contact.
