I had a similar problem a few months back - newish battery going flat, not
much drain.

It turned out that it WAS the battery - it was not holding charge on one of
the cells, and would go flat if I left the car for 2 days.

If you have a voltmeter, check the voltage when it is drained. In my case it
dropped from 12v(-ish) to 10v(-ish)
I don't remember the real figures, but it was clear that it had dropped by
one sixth (=1 cell).

Anyway - do NOT discount the battery (can you borrow one from another car
??)


Good luck

A 90% charged battery (=full) is 13.8 Volts. With a short-circuited
cell 11.5 Volts.
