If you still have the original 24 to 12 volt transformers, the one marked “ PERMANENT” is hard wired to the batteries and draws power 24/7 unless you turn it off. Its purpose is to preserve volatile memory in devices like the stereo radio station memory function.

I don't think you have a "Voltmaster/Batman," rather you may have a Mastervolt Battman😁. Your boat originally came with a Xantrex Link 10.
I think you can get it to read amps alternating between zero and 0.1. As you know the battery monitor will use a minute amount. Also, it is possible that your monitor is not totally accurate. And, remember the shunt on your monitor is not totally accurate to zero. It will have a small resolution. I don't know about the Battman, but the OEM SM Xantrex Link 10 has a 0.1 amp resolution.
So, if you are using the battery monitor to determine the point that you have zero amps, you're probably using the wrong thing. In fact, with the permanent OFF and a monitor reading between 0 and 0.2, you are probably there.
I hope this helps you.
