Car is dead
 

My 2005 r52 is dead. I bought it, not hearing it run. The car had a bad motor. Motor rebuild and sound great but today when putting it on the ground in drive it went 4 feet a dead.

no codes, no loose connections, new battery, starter, alternator.

any ideas?

the car is an automatic non S

I can not find the battery drain. It has been narrowed down to the supply that goes down towards the alternator starter but they are both new. Anyone knows what else is on that supply run
