It is not charging the battery and if I keep the vehicle running too long it tries to burn up the alternator. I’ve replaced the battery, battery terminals alternator and the 120 fuse in the fuse box I’m stuck.

I would check the main system ground from the engine to the battery and from the battery to the chassis. Also, when the alternator is charging what is the voltage?
