Hi i have a terrible problem with my cobalt ss sc 05. Ive changed my batterie over 4 times and alternator and my car keeps dying. Today i fully charged a new batterie to see that would happen. The car started up after a little effort i let it run for about 10 minutes and then tried again it only did a clicking noise its was just a single click. After that i let the key on accessorie to see if that would still work and all i could hear was a clicking in the fuses and my theft light kept blinking. When i took out the key i could still hear the fuses buzz a little bit so i took out the batterie i really dont know what going on its been doingthis for a while now.

 

ok weird. first make sure that u have a new batt and new altinator at the same time, cause bad battery kills the altinator. second, obviously ur power is going somewhere, check all the connections make sure they tight. ground and power. sounds almost like ur batt is grounding out somewhere. check if the positive wire is hot. if it is, then its grounding out a little somewhere, very dangerous, can start fire. see those things and let us know. we go from there

 

The positive wire did not get warm as i could have seen and i did change the alt and the batterie together and i still had the same problem so tried new batterie again and same problem the garage checked my alt and said it was running fine and i doubt alternator could kill a batterie almost instantly

 

I'm having the same issue right now 07 ss/sc. Alternator worked for a week then had a couple issues. Then worked perfectly for 3 weeks now it won't charge. This is the 3rd alternator
