2007 Toyota Camry Q&A

2007 Toyota Camry Question: If i turn my a/c on while driving the battery light comes on ,why?

when i use the a/c when driving it sucks all the juice out of the battery, and after replacing one battery,I used the a/c again and it started draining the new battery, so after charging the battery back to 100% and putting it back in the car i have been driving with no a/c on and the battery light has stayed off.is there any way that there's something wrong with the a/c system and not the alternator? -
Answer 1
Possible drive belt system problem! Any squealing noises with AC on? Need to know alt. output voltage. -
Answer 2
poss alt is not putting out enough voltage to handle the load -
