Re: Generator Failure

One thought is the regulator couldn't get an accurate idea of what the generator was doing. That is the purpose of the extra ground wire -- so the regulator and generator are tied together and see exactly the same potential.

With the regulator ground at one point and being referenced thru engine, mounts, linkage and not much with good direct conductivity to the generator there was probably a considerable resistance and voltage drop between generator and regulator. With the disconnected ground wire the regulator probably saw a low voltage and could have kept telling the generator to put out more.
