Hi,

All is not well with the X5. Even with the new alternator (mind you a lot better with the old one), it is still very low 13.5V. I did more investigating and started checking for voltage drops. Ground side is good (0.1V) but the positive side is 0.95V.

The starter stud where the two positive cables meet (from B+ and alternator) is getting hot. I can remove the 13mm nut from the back of the starter from underneath the car by removing the stiffening plate.

Already placed the order for the two cables and should arrive next week. It looks like the starter stud has not shown any melting plastics or anything. At least that's what I am hoping for since it will be a b**ch to get to the starter.

My plan is to "fish" the new cables using the old ones and hopefully hitting no snags along the way. I will keep you posted.
