Something was draining my battery.
« on: 06 June 2008, 06:33:47 »
Went to Marks last night and he stuck his AVO onto it.

By a process of elimination he discovered that the relay controlling the auxhilary socket was permantely on, drawing around 750ma.

Interestingly, only facelifts have this relay, and in a way, he killed two birds with one stone, as his facelift is experiencing similar problems.

Thanks a lot Mark :y

Yes, I discovered this after I could not understand why equipment such as mobile phone or satnav that I left plugged in (and hidden under the seat) seemed to be charging when I left the car, but was not fully charged by the time I returned a couple of hours later....

Anyway, good job you got it fixed.

Interesting.. Another failure mode to bear in mind. I wonder if this was only happening intermittently - because, IIRC, the standing current looked OK when AA got the meter on it.

You could be right, although it flattened a new battery after being left standing for a week.

Used the car extensively yesterday, it's been standing since about 4 pm yesterday, just been out to post a letter, battery was nearly flat :(

Now what, sticking relay has been removed.
