Battery Issue?
We are camping and I noticed something that I had never noticed in the 11 years we have owned the trailer.. We are plugged into pedestal power. When nothing that requires 12 volts is on, the 12v powe...

In my previous post, I mentioned that the adjustable voltage controls might be inaccessible once the unit is installed, but am not sure about that.
EDIT: Can you install it the other way around so the open board is to the front? That way you could get at A and B. Kind if loony of them to have the MBA with the LK feature if you can't get at it!!! :( Or else don't use the MBA, but get a deck mount so you can turn it the right way to get the two holes in front )
If you can get at the two controls A and B as seen in the above link, it is easy to do with a small screwdriver in the voltage pot when the other switch is made to "single stage". I have the deck mount LK and it is easy to operate A and B.
In the deck mount LKs, they have two holes in the side to get at A and B, which are open on the board in the MBA version, as seen in the above link.
If you just want it for the three stage operation, set it for that with switch A making sure the voltage is set to the right value on the pot so it does the right voltages in all three stages. ( It is confusing but read it carefully--if you mess up don't worry it won't break--just go back to square one and set it up.
Big thing is to have your voltmeter on it when turning the pot so you can see what you are doing, and not have it connected to the battery yet. Connecting to the battery skews the voltage you see on the meter. You just want to see pure converter voltage.
