I need to verify, but I'm fairly certain that the reg/rec I'm using is a

Saving the generator from producing heat in both the rotor/stator and
generator.

Dear Ernest,

I'm afraid that only addresses the power OUTPUT, not generation. So
long as the magnetic field is present and is being cut by the winding
of the coil, a voltage WILL appear across the coil, as will some
residual heating effects. The regulator can isolate this from the
battery but that only addresses the output-side of the equation.

That's a guess of course -- we're using different components. But in
a permanent-magnet type dynamo the Field is always 'on' so to speak --
there is no 'control' as is found in the typical generator-type dynamo
since there is no Field winding. In either case, I think your method
of installation calls for a bit more head-work.
