[sdiy] hammond issues

[Jay Schwichtenberg]

Bill,

"The tone generator assembly in which all the tones of the organ originate,
is driven at a constant speed by a synchronous motor, located at the left
side as you look in at the back of the Console, Attached to it is the
vibrato scanner. Ad the synchronous motor is not self-starting, it must be
brought up to speed by a starting motor at the opposite end of the
generator.

The procedure for turning on the organ is as follows: Push the "start"
switch up (M-3, M-100) or in (M, M-2) and hold it for approximately eight
seconds. This allows time for the starting motor to bring the generator up
to slightly above the synchronous speed. While still holding the "start"
switch, push the "run" switch upward to it's "on" position. This turns on
the synchronous motor at the same time introduces a resistor in series with
the starting motor to reduce its power. Hold the "start" switch about four
seconds longer and then release it.

During this time the braking action of the synchronous motor, together with
the reduction in power of the starting motor, brings the system to
synchronous speed so that the synchronous motor can carry the load.

To turn off the organ, push the "run" switch downward to the "off"
position."

Good luck, let us know if this helps, I'm going to bring up and refurbish a
M3 hopefully this winter.
