As an "almost" solution I fitted a 3-PH rectifier/regulator pack from a
later model and connected each alternator coil to its own arm of the
rectifier with the common connection to the third.
Its the thyristor type regulator, not the field coil control type so it
works with any PM type alternator, both coils are permanently on the
rectifier and the regulator catches any time its run with side lights or no
lights.
If I run with main beam all the time and only start it with the starter, I
have to take the battery out and charge it every now and then.
Its still on the back yard with a rusted through swingarm and siezed in
bolt - so the as new battery is now entering its second year on the
Optimate.

Your crappy old 1970s clunkers don't count.

Permanent magnet alternators and rectifier regulators haven't changed
in the last 40 years, asshole.
The voltage output of a PM alternator depends upon magnetic field
strength, number of windings in the coils, and the speed at which the
windings and magnetic fields intersect each other.
Your *assumption* that the OP was saying that the PM alternator on his
VF500C was putting out 14.29 volts at idle is ludicrous.
A PM alternator *will NOT* produce enough voltage at idle RPM to reach
14.29 volts and then shunt excess voltage to ground.
If a PM alternator was *designed* to produce that much voltage at
idle, it would need (a) more windings, or (b) super magnets in the
flywheel.
And any typical RR with a zener diode triggering one or more silicon
control rectifiers would be shunting excess voltage to ground *all the
time.*
If an engineer needed 14.29 volts at idle RPM, he would use an excited
field
alternator instead...
