Diffidently check you cables. If you have a digital voltmeter that would be a great tool to diagnose the problem. Before you start your car the voltage directly on the battery will read approximately 12.5 vdc or higher. Once car is started the alternator will increase the voltage up to a minimal of 13.8 vdc or higher. If lower Alternator is subject. When car doesn't start and you try to turn it over a few time. Check to see if cables are getting warm. Also have some look for and sparking during turning it over around the cable area. This would be an indication of resistance that could cause a voltage drop minimizing current to turn the starter. They’re other possibilities, but if you have less then 13.8 vdc when engine is running. Alternator is very subject. A new alternator from AutoZone is 146usd. With a lifetime warranty. Should you choose to replace the alternator yourself, it is very time consuming and a good chance of causing damage to the alternator being removed making un-rebuild by yourself. With all the labor involved I would replace it with a rebuild. You should read of others who have done it such as myself on the bulletin board. I have always done every car repair myself and the Saab Alternator is a challenging one. Should you choose to bring it up removing the suspension support or remove the exhaust and out the bottom. Measure the voltage with motor running and take it from there.
