I have a Cadillac CTS 2003 and it wont stay running! Took it to Advance Parts and the put it on the machines and they said the Alternator wasn't charging the battery. So I brought a new Alternator and battery. It ran fine for a day or two. And now it wont stay running again. Took it back to Advance parts and the put it on the machine again. And again it says Alternator wasn't charging the battery. So I had the Alternator tested and it works 100%. Now the battery snit getting charged because I need a jump to get it started. And still it won't stay running once I get a jump. Come to find out the reason the battery was out of cold cranking amps(remember this was the new battery). So I brought a new battery it keep the car running for a day or two just as the other one. And now the same thing. What could be the problem Please HELP!
