I have a new coach, and it did not sit on the dealer lot for a long time. Bought it a few weeks ago and currently I have it stored about 70 miles away so I don't have access to see it and verify details. Just this past weekend I verified the AGS unit settings, the factory had the voltage start set at ~10v, which is why the batteries got to ~11.4 while I was monitoring when or if the AGS would function (no AGS documentation was included in my manual bag - Thor has sent me a digital copy). The batteries took about a 12 ounces of water each to top off, visibility and access did not allow me to see the starting water level, I was happy to just get some water in them.
I drove the coach home - 6 hours, so the batteries were initially (with low water) able to charge for many hours. Recently, I don't think I have been giving them enough time to recharge sufficiently, yet I also do not think they should have been drawn down as much as they have. Everything, except perhaps the battery condition, seems to be working as it should - even if I am just slowly learning what that entails.
Where do you set the "shore max" amperage?
