R33 GTST Electrical problem - please help

[Notorious-Sky]

Hello all !

I posted this already in Skyline Technical - but i wasn't sure if it would get a response there. Please pardon me for double posting.

When I first got the car a year and a half ago, battery would drain after two weeks of not being driven/started then after about an hour or so of driving it was good for another couple of weeks. Recently it has held a charge enough to start the car no longer than about two days without at least a 20-30 idle or drive. Charging system checked out fine as did battery (about 4 months old). I know there has to be an open circuit or ground somewhere but I cant seem to find it. Any ideas on where to start looking for the culprit, has anyone else had a similar problem ? Oh btw battery is standard setup in rear of vehicle, I understand this is standard on the R33.

Thanks for your input, it is greatly appreciated.
