Just got my 2005 Beetle and it's real purty. But it won't hold a charge overnight. Runs fine all day and charges up quick when I put it to the charger in the morning. Then as I start it through the day, it's slower and slower to crank. Has about 1.5 draw, pulled all the fuses for a parasitic check. All lights are off and a new battery. Mechanic thinks it might be the fuse box? I've read here that it might be the Monsoon radio? Any suggestions would be welcome! Thanks...
