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.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.

pretty sure the mach amp in the dash doesPull 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?
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.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.

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.Is this the Mystic that was for sale for ever on the SVT Forum? Guy was from Illinois too, I think, Just curious.
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.half a volt over a week will slowly kill a battery. look under the radio for the mach amp and disconnect it
I drove it to get gas. Noticed the volt gauge was lower than it was last year when I knew it was charging. So I got gas and came back home to put a meter on it. I’ll pull it off and have Oreillys test the alternator.What happens off-idle though? Do you give it a bit of juice and hold for a few seconds? Or is it always just idling?
Not sure your exact setup but factory alternators of this era are notoriously weak at idle. They may be rated for x number of amps but that number fluctuates in the rpm range. And it also depends on the regulator and in the modern era the ECU itself. If I were you I'd take it for at least a 5 min drive, ideally longer. Might change things.
