Re: Add an alternator charge indicator

I don't think it requires any more earths. The 3 phase output of the alternator is converted to single phase d.c. which is what is feeding the indicator circuit. As the indicator circuit is earthed, it is at the same potential as the 12v d.c. circuit. I think that the diagram is somewhat confusing, & what it is doing is monitoring that the alternator is throwing out sufficient power to charge the 12v d.c. circuit. :??:
