Greetings -

I have a 2002 S60 AWD that has developed a perplexing issue with the battery draining. After swapping out what may have been a good battery I am still encountering the dreaded no start condition. It used to only occur if parked for a week - Friday it happened after being parked for less than a full day.

Taking an inline reading off the negative terminal I can see where the car is pulling 4.24 amps (not milliamps - so it is a huge draw). Removing the jumpstart lead/connection in the motor compartment had no effect so I think I can rule out starter and alternator.

Removing fuses 28 and 32 each dropped my draw significantly (almost 2 each). 28 is "roof lamps, courtesy lamps, UEM garage door opener". 32 is "central electronic module:-ECPS-courtesy lamps-glove box lamp". Battery was still dead this morning - so I looked online, pulled fuse 27 ("front door modules") and now am down to a more reasonable .16 amps.

So now is where I admit automotive electrical is not my strong point - and looking at this list of components has me feeling perplexed about how to tackle it. Others have had this issue - but I don't see where anyone has posted the solution. Any advice or tactical suggestions would be appreciated!
