Ok........... The Tiara 41 should only have one charger. It may be located behind the cabin electrical panel (you may have to unscrew the panel (it should have a hinge on one side) that will swing open one the screws are removed. It could also be under the seating section port side, possibly behind a screw down panel. There is also a screw down panel in the lower locker just to the Stbd. side of the cabin door in the galley. It could be in there.

Your vessel originally came with Gel batteries. Gel batteries require a lower charging rate. Now that you have switched over to AGMs, you are not charging them fully. There is a set of dip switches on the Charles Battery Charger that can be adjusted to charge AGM/Flooded Wet Cell batteries. So once that is complete battery charger will take care of the batteries when the engines are not running, however your alternators are something different. Those are likely Balmar externally regulated. You will have to check to see if they are set at a level that will charge AGM batteries when the engines are running. If not, you may have to replace the regulators with ones designed to charge AGMs.

Good Luck!
