Yes, I switch the voltage regulator on every flight. The concerns that I
voiced regarding the alternator load came from an article in the American
Bonanza Society magazine, where another Baron owner saw similar behavior.
This article suggested that it might be a bad diode in the weaker
alternator.

As a matter of fact, I called the ABS today, and they suggested that the
observed difference could be due to a poor ground, and suggested
investigation of the same. I hope to do this in the near future.

Thanks.
