**SOLVED***. Replaced alternator, started now DEAD

[ALLUCZ3]

So after checking and rechecking all the connections it turns out the cable to the battery post was not clamping fully on the post though the nut was tight. Re positioned it and tightened it up and we are running. Just goes to show you check and then recheck. I'm thinking it was the week of 100f that fried my brain



Hi all,

Still nursing the e53 along. Replaced the alternator the other day, got it all back in and it started right up so shut it down

2 mins. later it wont start, no click, no interior lights, no nothing. Battery checks out ok, terminals are clean and tight.

Is there a main fuse in the one of the battery cables or before the fuse box that could have blown? other thoughts?

TIA
