[M] Alterpower alternator charging control switch

[Clarence L.Snyder]

Disconnecting the alternator PHYSICALLY, or gearing it down, will make
as much difference, if not more, than shutting off the field as windage
and friction losses are high. Under load at high RPM a change of pulleys
can EASILY give you 3-5 HP average.(while still maintaining adequate
output) Shutting off the field with a fully charged battery at wot? For
short term acceleration? I don't think so.
