Title: Battery Drain
Post by: Tommy on 31 May 2009, 11:05:37
I've moved this over from General Help.
I have a battery drain whereby after a couple of days the battery is flat. After trying various suggested things (thanks guys) these are my present results

Current draw from batt -ive to car -ive 0.71 (10amp scale)

Removal of fuse 6 ....... 0.41 (Radio)
Removal of fuse 12 & 6   0.18 (includes radio)

Does having a phone card in the radio draw any current when switched off?

I noticed while 12 was out that the climate control fan kicked in with keys out of the ignition!!

Anyone got any ideas now?

Oh yes Alternator charging at just under 14v with a small drop with aircon & headlights on

Having had a play this morning it appears fuse 6 runs the amp as the radio still works with it removed albeit silent

Original stereo equipment?

Any other non Vx accessories fitted? Phone, alarm, nav etc?

How old is the battery?

Battery is 2 weeks old

CCRT700 fitted and no - no aftermarket stuff

Try disconnecting the power sounder for the alarm under the bonnet -

Hopefully someone will be along shortly to advise where and how the easiest way to do this will be. I know its as simple as pulling a plug, but not being an Omega owner, I`m not the best to advise where the pug is.

Hi Dave,

I've already done that - although it made no difference I've left it disconnected for now

Unsure what else you have tried, but central locking would be my next thought, and then the removal of the head unit itself - (not simply pulling fuses)

Removal of the head unit also isolates the antenna, which is troublesome on many other vauxhalls also.

I did have a leak around the base of the antenna - perished rubber

that's not for your radio  ;) radio aerial is built into your rear screen.  ;)

True, but the Antenna base still has electronics inside it, albeit for the phone, and as the head unit powers that also - it can`t hurt to try to eliminate it. Its the same shape and design as the leaky radio aerials, so coulss till potentially give the same problem. Easier and quicker to initially pull head unit out than to fumble around disconnecting the aerial wires in the roof lining.

Thanks Dave - I'll give that a try.

I don't know if it's connected but I'm also having an intermittant fault with the drivers door speaker. It'll kick in if it's loud and bass enough

Unconnected, but a sign that the voice coil in the speaker may have gone - investigate and replace the speaker asap if necessary, as at the moment its intermittant, if it fails and goes short circuit (which it will soon) then can cause an expensive repair on the head unit.
