'88 5000CS Quattro Electrical Gremlin - Requesting Diagnostic Help

[Pat]

Robert

My brother had the same problem with his 88 5000S wagon.
The battery would always drain within a night.  I started removing
fuses until reading on the amp meter I had hooked up to the battery dropped
way down. It was the  radio fuse and etc. (4).  There was some
one on the list that mentioned that sometimes the chime relay goes bad.
I pulled out the relay and no more battery going dead. Did not effect
anything except the warning chime.  You might want to try this relay.  It
is on the Auxiliary fuse panel, second from left middle row( blue).

Hope this helps
