 GW> The early alternators all used vibrating contact regulators.

There was a gap of about 10-15 years in the dates of the cars I
owned. I guess I missed those.

 GW> Electronics was just comeing in then, and rectifiers were one of the
 GW> first parts able to cope with the automotive environment.

Yes, that is true.

 GW> One thing to remember is that _all_ dynamos needed a current limiter
 GW> as they are not intrinisically self limiting.
 GW> Most alternators intrinsically self limit the current output, so all

Hmmm... that doesn't sound right. It couldn't be the change of
which part rotates and which doesn't. So is it the impedance of
the diodes that makes an alternator self-limiting?
