Back in January of this year, I decided to replace Helga's 5 year old Exide battery. There was nothing wrong with the battery, other than the age, and the fact that we were planning a trip to Mississippi to see our Son off to Iraq. I purchased an Interstate 750 CCA battery, and the trip was uneventful.

Last Monday morning, I went out to leave for work, only to find a completely dead battery. I drove the Bimmer to work instead, and picked up a replacement battery for the dead interstate. We checked the battery, and found a dead cell.

All was fairly okay until yesterday. I went to move Helga, and she started, but the engine cranked over more slowly than usual. This morning the battery was again dead. I jump started her and drove her to work. The service department checked her out, and the battery checks good. The alternator is putting out nearly 14 VDC to the battery. I have checked for anything that could be pulling the battery down, but can find nothing.

The only recent change was to replace the radio with a more current unit. The radio is completely off (except for the memory circuit) when the key is off. I did have to run a new power lead from the fuse panel since the original positive jumper was inadvertently pulled loose from wherever it plugs in under the dash (in the wiring harness) Anyone know where it plugs into the car?

Any ideas? All interior lights (including the glove box light) are off as well. I'm at wits end on this one.
