Thanks for the replies guys, powersounder is already gone and all lights, extinguish as they should. The drain quoted is after leaving the car for a couple of hours with the ammeter in line with the battery. I haven't looked at the aerial amplifier, would this not power down with the radio removed? The isolating of fuses in order is the process I employed but as I say it is not cleared by one fuse. I have to remove either the two right hand large fuses in the engine bay or fuse 12 and 20 together under the steering wheel to drop the bulk of the drain to 15/20mA which I think is acceptable for a 'sleeping' alrm system.

Omega Electrical and Audio Help / Another Battery drain problem

« on: 10 January 2011, 08:03:38 »

I have an Omega B 2.0DTi estate with battery drain problems and I am running out of ideas. When the car ‘goes to sleep’ there is a 215mA drain. I have replaced the battery, isolated the starter, alternator, and then proceeded through all the fused circuits. Here comes my confusion, on the fuse board below the steering wheel if I remove fuse 12 or 20 I get a very slight reduction, when fuse 12 is removed after a few seconds the cabin blower starts at full blast and then reduces to slow and continues to run. When both fuses are removed together the drain drops to a few mA’s and the fan stops. I also have a airbag light, whether this is related I haven’t got that far.
When locking the car normally all lights and displays extinguish, vanity and glove box lights are off, removing radio has no effect.
Running out of ideas, can somebody find me some inspiration.
Many thanks in advance.
