Safrane battery drain

Hi everyone I am new to the forum, and may have posted to the wrong forum. I have a 1999 Safrane 2.5 auto.
The car was preregistered by Renault and I bought it in 2000. I am very pleased with the car but over a few months, if I leave the car over the weekend I have to start it
using a backup system.
The alternative is to uncouple the battery, couple up on a Monday, and car starts fine using the external power source. Car auto electricians found a fuse used to control radio, internal lights and trip recorder.
and fitted a shunt so radio could work, not ideal.
has anyone experienced such a problem and was there a solution.
Could anyone advise on a wiring diagram for this car, my chum an electronics engineer is going to have a look when the weather gets better in Scotland.

Welcome to the forum Graham - have you had the battery checked? Could just be that the battery's past it's sell by date?

Hello,and welcome to the forum.
The way to find a drain on a battery is to disconnect the negative terminal of the battery,and connect an ammeter between the lead and the terminal.If there is any drain higher than 0.3amp,then there is a problem.
If you find you have a drain above this,then it's time to start removing fuses from the fuse box and checking whether the drain drops below the 0.3amp limit.
It the drain is less than 0.3amps,then suspect the battery.
Remember to have the doors closed on the car when doing the test,otherwise the interior light will give a false reading!!

I'd rather push my Alfa than drive a BMW....

Just a quick point. Someone posted yesterday that the glovebox on their car would not close properly and the light was constantly on. Could be a cause.
Alternativley I have known the interior boot light to stay on when the boot/tailgate is closed. Just a couple of quick checks?
