Hello all,

I have a 1989 Audi 200 turbo quattro and just recently the battery stopped wanting to keep a charge.

If I drive it everyday it is ok. However, If I let it sit over the weekend then Monday morning it is completely dead.

So I put on a new alternator (twice) and a new battery (twice). Still no fix.

I really don't recall having this problem until I filled in some empty slots in the fuse box. Maybe the previous owner had these fuses
removed so It would charge. But after thinking that this might have been the problem, I could not remember which fuses were

already in there and which ones I put in.

Some people tell me its not charging because of a ground wire, relay, or even a burned wire.

Some friends told me that there was an quick and easy way to find exactly what the problem was but they could not quite remember.

Is there anyone who knows how to find out what is causing the battery NOT to charge or how to narrow it down?



Thanks
Hohn

 

What you can do is get a test light, and clip it in between a battery terminal and the battery post. If you have a current draw the light should light up (you can also use a current meter).

Pull fuses until the light goes out and that will tell you what circuit the current draw is coming from.

The fuseboxes on those car are notorious for corroding causing all sorts of strange issues, might want to pull the fuse box and inspect the copper traces on the underside, any sign of green flaky stuff means that water has found it's way into the box and is working it's magic.

 

That makes sense. Thanks for the help Scotty.
