Battery hook up

2017 Thor Freedom Elite 29fe
I am looking to track down why my camp battery keeps going dead when in storage mode within a couple days.I know the battery is shot at this point and want to make sure the wiring is correct before replacing. The battery has three wires connected to the positive side, two banded red and one banded yellow, and one wire attached to the negative pole, banded red. Is this correct?

Battery drain

This could be a wide variety of things. First, charge the battery. Second, lift the positive battery terminal while having an digital ammeter (20A range) connected between the battery post (+) and the removed battery wiring to see what the drain current is in the "store" mode. Change the meter to a lower scale and repeat to actually measure the draining current. If the measurement is under 50 mA or so, that is probably normal due to some low current things tied to the battery even when the system is in the store mode. Leave the battery disconnected for a day or two and take voltage readings over time. The battery voltage will initially decline by 0.5-1V due to the previous charging but after a couple of days of being disconnected, the drop should only be in the tens of millivolts. If the decay is worse, then the battery itself can be either leaking or internally shorted (typically 1 cell or 2V) If the battery goes below 11V when disconnected there is a shorted cell internal to the batteyr and you need to replace it. When you get a new battery, repeat the tests from the start above to identify the problem.
