'87 Saab 900 no start. Alternator?
Still getting to know this inherited 900. It died the other day driving uphill... started a sudden stumbling, then quit after a moment. When I tried starter in Park... nothing except a click and some dash lights. Same in neutral. Tried jump start from another vehicle... no change in Park, but fired right up in Neutral????
Managed to drive it a couple of blocks home, but died again in driveway.
I charged the battery. Still no start on its own, but will start with jump but only in Neutral.
I have done a preliminary check with multimeter... battery seems charged, but no bump up when running.
This suggests alternator... but still peculiar that it won't start in Park, and only starts in Neutral with a jump.
Maybe a ground problem?
