....
To wrap this story up i got towed to the nearest mechanic shop which was a pepboys. They tell me the battery was drained and dead because the alternator wasn't charging it.
Paid for the work of a new alternator and battery. Just to leave the shop and the battery light to still flicker on and off within 2 blocks of driving off the lot. Car still running but the light still came on after all that so im assuming the issue is still the issue. Took it back to them and nobody knows shit to actually fix the problem..

Somebody with information or experienced this please help me!!

Battery light flickering = alternator problem. Most of such problems are due to worn alternator brushes (a less than $10 part, and very easy to replace). At 180K mile mark, the alternator brushes will be on last legs.

Your first mechanic replaced the belt and tensioner unnecessarily.

Unless Pepboys didn't connect the alternator securely, you've got a bad alternator. No need to try to take the matter into your own hands. Go back to Pepboys. For problems like this, they normally have 1 year parts and labor warranty. Insisting on another alternator (free parts/labor, of course). Most likely, another alternator will solve the problem.

There's more to the charging system than just the Alternator?

Seriously, let me know what are the "more" of the charging system? Alternator is directly connected to the battery.

I think the original mechanic got it right the first time. Tensioner pulley. I take it you walked away and didnt get that done right? Did I read that correctly?
Anyway I'm with others on here, get it to an Auto Electrician pronto or at the very least someone that can use a professional level scan tool and knows what they are doing. NOT Pep Boys or similar
Do this before you increase the damage $$$

Care to explain why "tensioner pulley" has anything to do with the problem? It doesn't even affect belt tension.
"Auto Electrician"? Never heard of such profession. Here in the US, any 1/2 competent mechanic will be able to diagnose and repair alternator, starter problems.
