It started earlier today I had been driving about and hour got home and cut off my car. I came back out about 20 minutes later to head out. I opened my car and the dome light was on. I turned the key no click or turnover and all power inside the car went out. I popped the hood took the batt cable off and put it back on. The dome lights came back on inside the car. I turned the key, got one click and power inside the car shut off, no turn over. Then I got the Idea it could be a dead battery so I hooked some jumper cables. While the care was hook up I could turn the key and get the clicking sound and a small weak rrrrrrrr where it was barely trying to turn over. Just to make sure I took the Battery to a local Auto store and they checked it all. The test came back all good fully charged pushing good ampage. He told me its possible it could be the starter. What do you all believe is causing the problem. The battery is 1.5 years only and the alternator is about 1 year old in the car. Thank you.
