Engine Mechanical problem
2006 Chrysler PT Cruiser 4 cyl Two Wheel Drive Automatic 41000 miles

Hi,
about two days ago, my battery light went on when I was on an incline. I went to my mechanic who tested the battery and said it was charged. We turned the car on and off a few times and nothing. Then the battery light went on again later that night. I rinsed off some of the corrosion on the battery with water and it was fine for a day. Then, when i was going up a hill yesterday, the battery light went on again and has stayed on since - the cable connecting to the battery seems firm and only one of the cable attachments to the battery has corrosion - what should I do?

If the battery is in good condition with clean and tight posts/cables-have the alternator load tested might not be putting out or the battery is not taking the charge.
