Battery drain

[bigwinn]

Need some help on this

Got a drain on the battery on the 325, nothing is knowingly left 'on' and alarm is switched off, battery was new 3 months ago so that's not a suspect...

Sitting for 4 days and it won't turn over, needed jump starting.

Where to look?

Any tips gratefully accepted.

Update

The wiki guide was invaluable



Ammeter across the terminals, reading of 0.7 rather than 0.3 and was fluctuating between 0.7 and 0.2...

until fuse 24 was removed

so as that powered the radio thats been disconnected as a starter for ten- however as it fluctuated I suspect the aftermarket alarm- which was not armed at the time of the test

thoughts?

I had the same issue with mine. The alarm, even when unset was draining the battery. Once the old alarm was removed the problem never reoccured.
