Battery Discharge 650i

[jenksy0198]

HI all, I have been suffering a slow discharge from the battery which has resulted in low cranking amps. Car isn't doing that many miles so put it down to low charging so set up a regular charge up practice. I think something is drawing on the battery. After a closer inspection I think it is the glove box light...why? I am assuming the glove box light is activated when the opener is released and the two sprung clips release from the bars located in the opening part. I am assuming this as I can't see any other sprung clip that activates the glove box light.

However, when I press these sprung clips in by hand, either together or separately, the light stays on. This would explain why I am experiencing this slow draw on the battery. Does this sound correct or is there some other sensor that controls the light on/off in the glove box. Seems my only solution would be to remove the bulb in the glove box which is no big deal.

Hi bud. 
the easy way to tell is to put your mobile phone on record and leave it in there. … I would assume the switch is on the inside of the clip, the female part in the dash, rather than the male section on the door, there would have to be wires to it so it wouldn’t be on a hinged door. 
 

How quick does it drain the battery?

how are you checking the amps on the battery?

Now that is a good idea. Will check it out

Or you could take the bulb out of the lamp and see what effect it has on battery drain 🤣

Just looked at a wiring diagram and there is a 2 position switch but no location I would assume you have had your fingers on it

OK to close this out, batteries have a life and it looks like mine, which was purchased in 2019, has run out. Because the majority of journeys in the E64 are relatively short it looks like the cycling and cranking draw on the battery is taking its toll. The non cranking experience has continued so will invest in a new battery and put some regular longer runs in. Hopefully that will sort the issue I have had.
