Thanks for the resource and the idea. Yes. I suspect something like that but the wiring is so suspect I'd like to have it examined and go forward with restoration. I'll try contacting @OTRAMM. I don't mind 47 miles to get it to a good person familiar with 330 year old Land Cruisers.@OTRAMM is highly regarded here, but he is out in bealton VA.
Sounds like you have a parasitic drain somewhere. I know in my truck I have to remove the face plate of my radio when I park it otherwise it will die in a couple days as well, as it is wired to alway be on even if the key is off.
