Car would not start; would not maintain a charge; but it could be jump-started. The main battery was not yet one year old. Testing showed that the alternator was charging properly. I speculated that the 'auxilliary battery' probably needed to be replaced. Jump started the car and drove to my mechanic. He ordered a new auxiliary battery and installed it. Completely solved the problem. Battery & installation $143.10
