Parasitic battery drain - SOLVED!

[njbray]

Had my car in the shop having a health check (cam deviations, suspension, etc) and gearbox oil change.
I had them spend some time on looking into the battery drain problem I have been chasing for a year or so.
Turns out it is the little red LED on the radio/dvd player! The reading shows it pulsing as it flashes, which is normal, but it is using way too much power to do so! Which was running down my battery after 5 days. Apparently they have had a few with the same problem - seems age related.
As I rarely use the radio I may just leave it disconnected or look for a new one.
