Paul,
I apologize .. I have been screwing off again ... I promised to try
this and then I ended up taking some other things apart, (putting
epoxy in the pin holes on the frame links etc) ... You obviously have
the diodes in the correct direction when you read 1/2 RPM on either
feed ... I agree with you ... it is like we are reading two cylinders
that fire at the same time and that isn't going to get it ...
Since you already are set up ... why don't you just go ahead and try
#1 with a different cylinder and see what happens ... you can't hurt
anything ... IMHO ...
