Question:
Chris (or anyone who knows) What type of AC motor is the "synchronous"?
( I'm gonna guess that the start motor is a AC series type, where the field coils are in series with the armature windings.)
Thanks
- Drew

Hi Peter,
It was just a guess on my part, I stand corrected.
The wiring diagram in my A-100 service manual does show one red and one
black to each side of the AC power supply, presumably the reds are one
winding and the blacks the other. If only one winding was operative, I
think that this may give the symptoms that Johan describes. The big
question is why? Is the motor faulty or the organ wiring?

Cliff - The polarity of the wires doesn't matter, only that both
red wires go to one side of the AC and the 2 blacks to the other side.
These non self-starting motors don't have a clue as to rotational
direction, in fact if you can get it up to speed going in the reverse
direction, it'll lock right in! All of the synchro hammond clocks will
do this too, and I've tried it, it works. I didn't feel any younger
though.
