I am using the Mitsubishi 60-A; which I guess= is what came with the 20B.

=0A

I put on a larger size pulley to reduce the rpm.

=0A=

It has in internal voltage regulator, whic= h is powered, and provides field current, directly from the output via an i= nternal connection. 

=0A

 

=0A

I use the = internal regulator, but made the relatively easy mod of disconnecting the i= nternal connection from the output so I can provide that from an external c= ircuit.  In that circuit I have the =E2=80=98crowbar=E2=80=99 over-vol= tage protection (bought from Aeroelectric Connection). It connects across t= he circuit breaker; and in the event of over voltage (I think at 16-16.5v) = it shorts to ground and trips the breaker.

=0A

 

=0A

Initially I found that the charging voltage was on the high side; som= etimes up to 15v. I realized that the regulator was then reading the voltag= e from my external supply; which after traveling to the battery and through= my circuit (battery in front, engine in back) had some drop; thus causing = it to charge to a higher voltage. Solved that by using the external circuit= to power a relay close to the alternator which powers the regulator from t= he output.  All is well.  Dave Leonard has the same setup; and = same story.
