- What was decided off-line was that the alternator has excess power
- to offer, and so when at low RPM generally is still putting out
- sufficient power. Therefore, I imagine (don't know for sure) that
- with an underdrive pulley set, the alternator output is still
- sufficient for automotive uses.
