[gasmanrus]

i got fed up with jumpstarting my car every 2 days so i got the multimeter out today. set it to amps, removed the -ve terminal and connected it in line.
ive read that a drain of 0.075A is enough to drain a car battery overnight & i saw a reading of 0.22A with ign off & interior lights etc off.
i then removed & fuses & found the current dropped to 0.02A when the central locking fuse was removed.
what can be causing this voltage leak? i dissconected the 2 central locking motors in the doors ( i was about to dissconect the boot & fuel cap motor/solenoid but it started raining!)

any ideas would be appreciated

Sounds like one of the motors is screwed. Be a good idea to disconnect them one at a time to isolate it, then replace it.

What car is it Rus and does it have an OE or after market alarm. Does the alarm plip activate the locking, as it could be a drain throught this.
Cheers

will be checking the other C.L. motors ant.
AL, its a bmw 320 with an o.e. alarm, but it does seem to appear to be coming from the C.L. circuit, i just thought the doors would be locking 7 unlocking to have to be using current??

cheers though

BMW, eh? Probably the electronic management system working out Pi to 150,000 decimal places.

Also check the CL switches for continuity.

could be a relay stuck on & drawing power constantly...might be worth checking the c/l locking relay...
