U might have a bad battery.
charge the battery overnight then load test it.
Your alternator should maintain the battery voltage at around 13.5 volts at 2000 engine rpm with a charged battery.
it's also possible you have an old worn regulator or brushes. Replace the regulator/brushes if they're around 140K miles old. You can replace the brushes for maybe $10 (get them at a BMW dealer if the Saab dealer doesn't have them) and a half hour the first time you do them but most people just pump for the (get the Bosch!) new regulator and brush assembly.
