Title: OOF mystery problem

ive found this same problem a few places in the archives.  unless im missing the answer it doesnt seem to have ever been solved!!!!!

it is a 250ma drain on the battery overnight going through fuse no 7.   if i pull no 7 i get under 5ma.

my mig handbook describes no 7  as "courtesy lamp 30a".   ive checked a few things and removal of fuse knocks out the electric seat motors, courtesy lights, boot light and rear cigar lighter.

the forum faq here http://www.omegaowners.com/forum/index.php?topic=90451.0  (http://www.omegaowners.com/forum/index.php?topic=90451.0) if im reading it right says the fuse is for electrically operated windows in 98-2003 cars.  it isn't.

any ideas what may be causing this mystery drain?  ive checked courtesy light, glove box light and boot light.

annoyingly the test is not very repeatable even allowing for the timer delay.  sometimes i get a 450ma draw even with no 7 pulled and i have to pull both fv5 and fv6 to stop that.

Taken from handbook for f/l cars -

No. Circuit                                                         Rating

6    Radio, infotainment system                              20 A

7    Check control, engine oil level, courtesy lamp 10 A
8    Daytime running lights                                     10 A
9    Automatic transmission, reversing lamps             10 A

Not 30A, but 10A ??? - same as in my handbook (2003 car)

I'll check the schems later, but if F7 serves the consumer delay, pull out that unit, as sometimes there stick on.

Yep, it does feed the contacts of the consumer delay timer. :y

the manual with my car a 2001 facelift elite says only

"No.  Circuit                Rating
7 Courtesy lamp             30A". 

the manual is "TS 1433-1" edition September 2000. page 191

when i pull fuse 7 the electric seat motors and rear cigar lighter don't work hence the 30A rating.  also the courtesy light boot light and glove light fail.

according to the same manual fuse 5 is "adjustable front seats 30A".  if i pull 5 the seat motors are dead if i put it back in and pull 7 they click but do not move with 5 and 7 both in they work fine. so it looks like 7 is something to do with consumer control.

the consumer delay was working, switches off around 5 minutes.  can it work and still drain after switching off?

nope its a pretty standard car.  as a few people have reported the same prob with the same fuse i am working on the assumption it is something standard on the car. the drain is 1/4 amp or 3 watt approx.

Pull the consumer relay, that will narrow down where it lies.

We'll get there in the end :)
