Voltage issue
I'm losing volts somewhere; it seems to get worse under a load. But it still seems low even at idle. I disconnected (from the battery) all the extras to rule out a short in those lines.
The alternator and battery (tested both) are both good. I was thinking the belt was slipping, but it seems fine. I noticed the tensioner pulley was moving at idle back and forth. So the question is under a load could it get worse and slip, then in turn my alternator isn't spinning properly, thus not charging the system? Or does that pulley move anyway and it’s no big deal?
I don’t hear any bearing not allowing something to spin, but the ac does seem a bit loud.

If the voltage is dropping at higher RPMs, you need brushes in your alternator. When they wear, and become shorter, the spring tension drops, and contact can't be maintained at the higher RPMs.
