charged over night charger read full 12.81 V
A knats knacker on the high side, so I'm guessing you read that without allowing the battery to settle for 30 mins or so after disconnecting from the charger.
Nothing of concern there though.
Altenator tested out at 13.85 V
That is the absolute minimum voltage required for charging, I'd expect to see 14V minimum when the battery is under load and the engine is at 2000rpm.
Did as suggested by Kevin and checked it out after 15 minute after closing the door read .4 to .7 Amps then settled down after a few seconds to .03 Amps
Perfectly acceptable current drain, no need for concern.
Did a drop test for about ten seconds reading stayed in the green but noticed slight gassing from two of the cells, is this normal :-/
Perfectly normal as a drop test pretty much makes the battery work it's nuts off to deliver the current.
I'd be looking at a slack alternator belt, and if it's not that then the regulator would be the next suspect.
PS
The last statement assumes the terminals on the end of the cables that connect to the battery are good, and that the wires are crimped tight.
