I have a 1994 Saturn SW2. Here is what it has been doing, and what I have done:
The radio and auto seat belts will intermittently work or not work, or flicker on and off...and the motor will occasionally act like it is going to die, but then pick right back up again as if nothing has happened. The ABS system has been acting up on me as well. The battery light will flicker sometimes. When I try to crank the car it sounds like it is struggling a little bit to get the starter motor to turn.
I took a voltmeter and checked the battery when the car was turned off, and I got a constant measurement of 10V.
I started the car, and tested it again with the voltmeter. This time, it would give me 10V, then jump to 13V, then go back to 10V, then jump to 13V....back and forth every twenty seconds or so.
I turned on the headlights and radio, then checked it again. This time I got a fairly constant reading of 13V, and only occasionally did it fall below that.
Bad battery, alternator, or else?
