I hope you are aware that the so called disconect switch disconects pratically nothing! Purchase a marine type disconect switch and install it next to the battery, one that disconects everything for storage, that should help.

Your disconnect switch is obviously not wired the same as mine.
You say "engine started right up"? The house battery has nothing to do with starting, and neither does your disconect switch. The disconnect switch is wired to your house battery, but leaves thins like your steps, LP detector, and sometimes the radio, stereo, which draw power and in some cases run down the battery.
To the OP your measure of 12.45 volts on the battery is almost dead. The engine alternator should have been charging as you drove. You either have a big drain on the battery or the battery is bad!
