1) Specifically what readings are you seeing?
2) Who checked it, and how?
3) What were the circumstances behind getting that new alternator?
4) Have you checked all battery cables at _both_ ends for clean, solid connections?
Bonnevilles have a reputation for eating their alternators, and your rebuilt one may be a bit flaky or just not holding up under the load, plus your battery cables may not be properly delivering additional backup juice from the battery at times when your alternator is maxed-out under high load.
