I had got bad advice that the solar panel was not big enough to drain a fully charged battery over a few days. Solar panels will do this. Forget science that someone tells you. The reality is in the facts. A man with experience is more than a man with an idea.
Glad you fixed it. Education still matters, but I'm not going to try and convince anybody on this one.
There could be several factors contributing to quick discharge of the batteries: bad battery, bad diode, and/or other loads. Could be bad diode AND loads running. After all your posts it was still not clear whether you disconnected all the loads. The "switch" that you were referring to tells me nothing. Disconnect means disconnect at the battery.
