[s-cars] Alternator problem - Help!

[Andrew B]

I'm on board with that.  If your brakes are firm as you described on
QW, then it sounds like your brake servo isn't working right.  AFAIK
that's a mechanical system, not electric.  It's run by pressure from
the PS pump/bomb system.  It SOUNDS like something isn't turning the
alternator nor the PS pump to give you brake boost nor electric.  I'd
double check that tensioner and belt.  Maybe it slipped off, maybe
it's not cranking right, maybe it's too long or something...

How is the steering feel in the car?
