Got the old alternator out and the new one in WITHIN ONE HOUR! WOOHOO!
No three days of SAABing.
And the car is back to driving normally. The instrument panel is not as bright as it used to be. I am told this not an issue of the dimming switch. A new mystery.
It was an adventure when we had the battery checked out. It was still good, but read there was about 2 months of life left on it. We chose to replace it now. Comedy ensued and three batteries later, it was installed with enough clearance from the quick connect for the hood to close. We had to go with an economy version.
The car works!
