You've got a nut missing on the back of the tensioning device. That could be a big part of the issue. When its cold and the belts are tight it seems to charge and work ok. Once the belts warm up it gets loose and wont charge properly. It will also cause the bolt hole to be out of round and that will cause problems as well. Before digging to deep into it I personally would get a nut on that bolt and adjust the tensioner and see if that makes a difference.
 I would also check the rest of the bolts as you can see the powdery rust on the bottom bolt indicating its not as tight as it should be. The super shiny spots on the pulley also indicate belt slippage.

Good catch i'll fix this tonight

That is the regulator. However that is a replacement. So a prevoius owner has had an alternator problem before.  If you look at the black above the regulator you will see the four screw holes where the orig reg was mounted.

Can you post a pic of the right side inside the electrical box? Cause you are around the time newell switched from solenoid connection of alternator to battery to diode based isolation. A quick pic will tell the tale.

Here is that picture
