     I think that you may have created a problem. I was somewhat puzzled
by Scott's description of how he polarized his generator. It almost
sounded as if he had the engine running at the time. Hope not.
Polarizing the generator means to give an initial magnetic polarization
to a piece of iron at the field windings. After this is done, the
magnetic field will induce current into the armature windings in the
proper direction. The way polarization is easily accomplished is at the
voltage regulator. With the engine stopped,
momentarily coonect a jumper wire between the D (Dynamo) terminal and
the B ( Battery) terminal. It only takes an instant.
     If you're seeing 18-19 volts of ouput, you may have fried your
voltage regulator. Keep an eye on your battery electrolyte, and your
