Battery Drain

[BEEMIN]

Hi members

I own a 1992 E36 318i

I have been having some electrical problems.
I have a new Optima Red Top Battery and a Reconditioned Alternator

Something is draining my battery , i have disconnected my alarm and my sound system .

After about 12 hours when the car is stationary , i try to start it again and i cant. My battery goes flat

Has anyone had this problem ?
I did some reaserch and found out that the E36 Air Con systems used to stay on even when the car was off and cause the drain.

I have taken it to the electrician many times and they can not find the train.

Any suggestions as to who i can take me car to ? Or what the problem could be.

Thanks heaps guys
