How old is it?  Disconnect it and see if it still drains down in a few days.
This has happened to me with an abused battery that charged fine, started
the car, but drained down in a couple of days.  Otherwise you can pull fuses
until it stops happening to isolate the problem circuit.

Greetings all,

                My '90 syncro westie has a voltage leak somewhere. Battery
goes to zero after 2 days of the camper not being driven. Van runs normally,
shows 13.5 volts while running through my digitool. I recently replaced old
battery thinking it was the culprit without checking it. It was about 5
years old so I presumed it was at fault. New battery now gets drained. My
question for you electrical gurus on the List, where would I start to track
down this evil gremlin. Everything seems normal but obviously is not. The
only constant drain is a car alarm LED that has been in the camper for 22
years.

Thanks for any words of wisdom.

Rick
