We installed a new starter, new alternator and got a new battery, something is still draining the battery and the battery symbol comes back on in message center.

Hi,

My first suspect is a fusible link that runs between the starter motor and the alternator.

If you look at the pics below, I highlighted the fusible link and included the entire charging system wiring schematic. Note that it goes to a red wire and runs battery power to the alternator.

Check to see if there is power at that wire. It should have battery voltage at all times.

Let me know what you find.

Take care,

Joe
