I would suspect the alternator. Sounds like a diode may have blown or one of
the slip ring brushes is shorted.

Quick questions. I have 66 Malibu BB. While running at idle the battery
is charging at approx 17Vdc. I have a Delco Remi with external
regulator. I worry that this is too much and don’t want to damage new
battery
. I also have a electrical short I just can’t seem to find. With battery
disconnected and the key out I find a resistance of around 20 Ohms,
indicating a closed circuit or short. I have pulled all of the fuses
and taps but can’t get the short isolated.
Any ideas or recommendations greatly appreciated as always.
