Battery drain

[Cloggy Saint]

I know for sure that I have a drain on my battery and haven't had a chance to do the test yet, but as my stereo is wired to a permanent live (can't remember which) would this be a likely culprit? When switched off the stereo display is blank, no clock or anything like that.

Assuming it's wired and working properly, it wouldn't be near the top of my list of suspects, but there's no need to guess. Half an hour with a meter should find it.
