your sorrow,
you will find that the diodes are not up to the task. To do this the battery must be
taken out of the
loop since it will act very much like a "crowbar" voltage regulator. Many smaller
motorcycles
have used the battery as the sole regulator, and many a headlight has been taken out

by a sulphated battery not doing it's job This is a tougher job in an aoutomobile,
since
the alternator must spin fast enough down at 1500 rpm or less, while not frying the
system
when you downshift into 6000 rpm.
