I bought a new battery for my 96 Explorer 4WD V6 5 days ago. I stopped to get gas, and had to get it jump started. I went back to AutoZone, they checked the battery and the alternator. They said both were fine. They recleaned the terminals and it started up. I also just had the transmission rebuilt about 3-4 weeks ago.
Today, my it wouldn't start. I had to jump start it, I drove it for about
5-6 miles afterward and then it still wouldn't start. So I had to jump start it again. On the second drive, I noticed that if I turned on the A\C with the blower on high, the engine would cut out for just a second, almost to shutting off. Also the battery light would come on in the first few minutes when I hit the brakes. After 1/2 hour drive, the engine won't even crank. While driving I watched the voltmeter, it was OK, it bounced slightly when I would turn on the turn signal, it's always done this. And would also drop slightly when I rolled a window up or down, again always done this.
Did I get a bad battery? Or is it possible something else is at fault. This only started after getting the new battery.
Thanks.
