And, when it dies, it dies! (ask me how I know).

If you're going to drive with no alternator, I'd suggest the following:
  • Put a spare charged battery in the trunk (to get you back home)
  • Keep an eye on your battery voltage on your cluster
  • Make sure your AAA membership is current
See my saga for my air-cooled 525i engine:
