So the battery light on my 6 will come on for a split second if I get on it like I'm racing. I was hoping it would go away but it hasn't! It did it last night for the first time in a couple of months. Should I take it in or is just a glitch! I do have a 1 year old battery in the car, so that's not the problem. I also have an alarm system hooked up to the battery, an Alpine radio that is grounded to the extra fuse, and a 12inch woofer. Is this just draining the life out my poor battery, or could it be my spark plugs. I have 56500 on the car and the original spark plugs. Any ideas before I spend a butt load at the dealer?
