1991 Sevelle (Not STS)
High voltage warning
I rebuilt the alternator (New voltage regulator and brushes)
Diodes checked good
Field windings not shorted to ground
Voltage swings from 14.1 to 15.8 and higher
No wires rubbed through in harness or to starter
Manual shows BCM as the actual voltage regulator, rather than this alternator controlling its own voltage as in other Delco alternators
Time for a BCM change?
If so, does anyone know the part number and a good source?

Thanks, Bill Childers.
