I have a 1999 saab 9-5 with 168xxx miles. Just note there is a used alternator in the car from a junked saab. I installed the alternator (what a F%&&*). Car ran fine, until the other day 6 months down the road. Im driving and all the warning lights go on. I stop turn the car off and it will not start again, kinda like the battery is dead. Got a jump, all lights turns right over. Turn it off, starts right up. Few days later it happens again, gearbox light with fault code car is in LIMPHOME mode. Got home turned the car off, started right up. Left again to get a radiator flush, car dies on the way home and stalls out while driving. Battery completely dead. Jumped start right up (limphome mode) Got home turned the key to on position for about 3min and the car would not start. Car runs ok without the battery hooked up, the alternator wires are secure, battery wires secure. Moved the batter ground. Anyways, please let me know what you guys think and I really like some help. Tomorrow i will be using a meter to test voltage. thx in advance.
