=C2=A0
Many years ago we discussed on the list various ways to im= plement=20 backup electrical sources for our electrically dependent engines. A great a= mount=20 of discussion was around permanent magnet type of generators.=C2=A0=20
=C2=A0=C2=A0 An idea was hatched and discussed, then forgotten. Except= I=20 didn't. Some years and a few sleepless nights later I set upon achievin= g this.=20 Most of the work was done and reported to the list quite a few years back, = but=20 at that time I knew I had to set it aside for some time as I had other=20 commitments.
=C2=A0 At last report I had finalized the mechanical aspect but had ma= de no=20 attempt to integrate it into the electrical system. I've now finalized = this and=20 yesterday ran the engine for the first time. Everything worked excellent! S= o far=20 it seems to have been a tremendous success.
=C2=A0 So I have updated my word document of the procedures for this= =20 modification. Including a wiring diagram.
For your entertainment I've put it on Google Drive in Word format = where it=20 can be accessed at the following link
=C2=A0
or for us Linux types in .odt

Comments, criticisms welcome
