Thanks again for the help. Ran the entire diagnostic on fuses and main fusible link was it. Disconnected alternator, which we had high suspicion of anyhow, and draw on battery dropped to within tolerable limits. Swapped alternator with one of the WPS 90 amp models from Concept Z and it all seems to be back to baseline. I noticed a bit of white smoke a few days before I noted the dead battery but, since the car was idle for a long time and I’m out of practice with a manual transmission, thought I’d smoked the clutch a bit. Guess it was a diode or two that went.
