Could still be a failing alt. I had one go on my gray 02 years ago. It would start fine after sitting and randomly stop charging and die.

Just starting to feel confident to take it out again and you post this reply? Thanks, it’s at the forefront of my mind.

Pull out the Bluetooth adapter when the car is not running and see how long your battery lasts. If it still discharges, it is something else. What else goes through the unswitched(always hot) circuits?

Is this the Mystic that was for sale for ever on the SVT Forum? Guy was from Illinois too, I think, Just curious.

Yes I did this experiment for a week now. Haven’t started it since last Saturday and checked voltage everyday. The battery started around 12.5 and is now at 12.

No. I think that one you’re thinking of was a highly modified one from Joliet area. This one lived most of its life in Arkansas.

half a volt over a week will slowly kill a battery. look under the radio for the mach amp and disconnect it
Yes but it’s better than completely dead after 10 days. Progress! Today is a test drive to make sure the alternator charges at all speeds.

I took it on a 40 minute drive yesterday at a variety of speeds. No issues. Voltage gauge looked good. It was on the R the whole time and only moved down between O and R for a few minutes. Came back and it was high 13s when running and 12.7 when off. I think I’m good!
