The other day, I went to start the car, it was dead. I had the battery checked. It failed. I replaced it. A few days later the car just stalled out when driving. I was able to get the car home and charge the battery. I had the alternator checked. It failed. I replaced it. The next day it stalled out again. I took the battery out and had it checked. It checked out ok, but only had a 4% charge. It took the battery home and charged it over night. I put the battery back in the car. It started. I took it to the store where I purchased the alternator. They checked the battery and alternator. Both checked out. It belt is not lose on the alternator. I do not know where to go from here. Any ideas would be appreciated.

 

May i suggest you check your terminals that are not dirty and/or are loose, also check your ground. My cb was doing the same and it turned out to be bad ground cable.

 

You definately need to check the system with the components installed. I suspect a voltage drop. Most likely in your battery cables.
