Question about Cars & Trucks
New battery and new alttinator
Alternator is not charging, if you got a reman it should be under warranty and if a shop put it in they should be able to test for free

You mean the chargeing light is still on .
It depends on what happened to make you replace the ALT .and battery in the first place. I don't know what happened but something did .
You need to test the chargeing system with the vehicle running.You will need a volt meter set to 20 volts DC scale you can get this for under 5 $ touch the black probe to the negitive teraminal on top of the battery and the same for the red top battery .You should read at least 14 volts if the ALT is chargeing the battery .
If not you likely fried what is called a fuseable link witch is basicaly reistance wire its like a fuse it burns out if over loaded.
Tipically you can find these wires running from the red terimial post wire that connected to the posivite side of the battery .
This would cause this problem if I read your problem correctly .
Or you could try this to find if you have a dead short something drawing the battery down with no key in it at all .
Disconnect the negitive battery cable engine off switch not on no key in .At the same 20 DC volt scale go from the posivite side of the battery to ground the engine block would be fine .If you read voltage you have a dead short that will kill the battery
