Yell... you want be able to retrieve any photos and minimum info due to fire in Oct,2019 . What I suggest if you register with Tapatalk go to 2016 archives and try finding that thread.That was TurboBuick source as a mobile app at that time.

Battery Drain? … If your radio clock stays on with the key off, then read on. By David Ellis member LSPBC Dallas

If the Radio Clock stays on with the key off, then if your car sits for around 3 days or more, it will not start. So what you end up doing is you jump start your car and then go driving around for fun and to charge your battery. To fix this problem you can just disconnect the battery each time you put the car up, but that is a pain. This battery drain drove me nuts and so I put lots of time into tracking this problem down. I knew that the drain was around 350 milliamps and it have to be something that happened due to age to the car to cause the problem OR when the car was new everyone would have just taken them back to the dealer to fix the problem. In other words the car did not come with this problem. I did pull fuses until I found the problem circuit and it was on the CLK fuse. The CLK has lots of circuits on it and is one of the two power sources to the Radio. This circuit remembers the radio stations, time and the radio will not work with out it. I remembered that GM car radios that have a clock go off, if you turn the key off, and you can push in the volume knob to get the time with the key off. So I went back to the Internet to search for problems with the GM radio clock. I found the there are tons of Turbo cars out there with this same problem and lots of guy with the wrong ideas as to what is wrong. I found that there is a circuit that controls the clock that some guys had this fixed by a radio shop but they really didn’t know what was fixed. I have had this problem for years and I wanted to know all about it. I searched more on the internet and found one small e-mail talking about a transistor in the radio causing the problem. I traced the guy down and called him in Kansas and he told me which transistor it was. I then pulled my radio and replaced the shorted transistor and clock goes off when the key is off. I can let my car sit for weeks and it will still start, and it’s a healthy start. There is now no battery drain period. So I found the problem and here is how to fix it. Look at the rear of the radio in the first picture and you will see what looks like two Pac-Man and above the lower Pac-Man is a cut out or cave and just inside the cave you will see the little problem transistor in the second picture. Go to a Fry’s or any electronics supply store and buy one NTE232 transistor, should cost $.49 or so. You will need to take the metal covers off the radio and remove the old transistor (NOTE the flat side of the transistor) using a pencil type solder iron by touching the ends of the soldered wires while lightly pulling on the transistor from the other side. If you do this right and are lucky there will probably three little holes that you can put the leads from the new transistor in. Leave the leads on the new transistor a little longer that the old one you just pulled out and replace with flat side facing the same way as the old one. Touch the ends from the other side with the soldering pencil and add a small amount of solder on each of the three leads. Do Not leave soldering iron on any lead very long as heat will travel down the wire and destroy the transistor.

If you can't fix the clock on issue, a Battery Minder of some sort seems to be the fix, no?

If you have a constant draw, you need a constant source of charge. Seems pretty elementary.
