Smile Blinking Battery Light

Hi everyone, I just replaced my alternator and my battery in my 2003 Beetle 2.0 Automatic trans. I fired the car up and the battery light starts to blink. As soon asd I take it off of idle it goes away. I drove the car for about a 1/2 hour and it still blinks at idle, but soon as I raise the rpm's a little the light goes out. Any thoughts?

Are you sure you got the belt nice and snug? The electrical system in these cars seems real persnickety. At least that's what I'd check first. Good luck with it.

Thanks for the reply. Is there an adjustment for the belt? I thought the tensioner took care of that.

I'd say that the alt. isn't putting out enough amperage at idle and when you increase the idle the amperage is increased to what is needed or more. So check and verify that the amperage is correct for you car.

Are you sure you got the right alternator? There are 2 different types for beetles.

I kinda want to step it up a little in the looks department and use a slightly different design.

I found the problem. It was the little fuse box on top of the battery. The 110 amp strip fuse on the black wire was almost severed. Went to Vw dealer and for $4.00 I replaced it and it. Runs like a champ...... Now , who wants to buy it? 84,000 miles on it, $6,500
