Post subject:  928 S4 Electrical Issues

Hi,

I have a 1990 928S4 and whenever I leave it for more than 24hours without driving the battery is flat.

I've been told its common on 928's so i had an isolator fitted to the battery so I can disconnect it easily when left.

I would like to get to the bottom of it and try and fix it, anyone have any ideas? are there common places to look first ?

thanks
