Took to the shop. they swore up and down was the battery. Battery swapped coded and within minutes of start up, it would trip a fault. they then thought it was the battery cable bulletin, changed that and same. Called another BMW Indy and they chatted and came to the conclusion it was the alternator. Changed that and zero issues. took four days in the shop to figure it out.
And what voltage did the shops measure over the battery poles, prior alternator being replaced?

As I would have thought a faulty alternator would be possible to detect in a blink, and it took 4 days, Im curious how the fault was shown/detected.

Thanks
