My brand new battery has been draining itself flat in 2-3 days and i've got an auto electrician look as to why, he has located a bank of 3 relays which seem to be causing quite a serious drain on the battery when the ignition is off.

They are situated up above the fust box on the drivers side and their colours are Red, Yellow & Green.  The Green and Yellow ones seem to be the culprits....

Does anyone have any idea what they are for?

[Kevin Wood]

At a guess, the timer for the consumer switch-off delay (turns off the accessory socket and interior lights after the car has been left for 5-10 minutes), and the relay that controls the accessory socket (rear fag lighter).

The Yellow one is the servotronic power steering ECU.

Does the rear lighter socket switch off after the car has been parked for 5-10 minutes?

Presumably the Alarm powersounder has already been unplugged ?

I'm not sure mine has one as it has a Vauxhall alarm system - ECU is under the drivers footwell, but i'll have a look anyway and see, if it has that sucker is comeing out!

Paul, the powersounder is part of the standard Omega alarm system from the factory.  I can't see any reason why plod would have removed it.  I assume you know where to look for it... under drivers side windscreen scuttle panel?

Will whip that out over the weekend mate

Ex plod highly unlikely to have one. Tell tale is the presence/lack of an bonnet alarm switch. No switch = no power sounder.

    I have two of the yellow and two of the green relays Paul but no red one.Possibly not all cars were fitted with the red one ?
   Do you know what the red one is for? ..........or got a part number for it.I have several orange/brown coloured relays (which I dont think are the correct one) but no reds,apart from servotronic relays and they live in the other side of the car.

Servotronic ECU IIRC. It's on the driver's side on later facelifts.

I'm still having issues with power drain...

Kevin in the first quote you said the RED relay is for the Servotronic power steering ECU but then in the second quote you said it was the Yellow relay, can we confirm what the red, yellow and green relays are for?

We've left the 10amp fuse in but pulled the green relay as that keeps clicking and getting warm even after swopping it with the one i got from Alb, we have also check AutoData for wiring references but its little help as only shows diagrams for the ABS and Airbag IIRC.

Autodata does list what the 10amp fuse powers tho and its lists quite a few items including 'Accessories'  Does anyone know exactly what accessories it powers?  As it could be that is causing my power drain, also the yellow relay i have in the car is 9 pin whereas the one Alb sent me is only 6 pin?



I'll try and get some meter readings to show the current thats being drawn with everything off and the car shut and locked.

As you said Al, no power sounded - I checked today.

[Kevin Wood]

Red relay is servotronic and Yellow is the accessory delay, I believe.

I will double check, though.

Green relay just switches the rear lighter socket, energised by the output of the Yellow timer.

Accessory delay?  What are the 'Accessories' though mate? There are 9 pins on that yellow relay so it must time delay a fair few things in the car?

What`s the part # on it Paul

I'll have to get it tomorrow Rob, have you got one of these by any chance.. 9056 6824?

I`ll go and have a look . What colour?

It's got 2 feeds, a single output and 5 inputs from door switches so I make that 8 pins. Close enough.

It powers all the interior lights, windows, mirror and seat adjustment from memory.
