2007 BMW E91 no-crank and a broken battery positive lead
Jake_Petersen_E91 reported a no-crank condition on his 2007 E91 N52. Replacing the starter, ground strap, and a relay behind the glovebox did not change the symptom. After removing the battery, he found the main positive lead broken inside the battery box. A few days after a replacement lead arrived, he reported that the car started.
