Third, remove screw (87) terminal box cover (84) and terminal
insulation cover (95). Untwist the lead wires with a hot soldering iron
and pliers, and remove the terminal insulation box (96) by lifting
straight up. The condenser (69) is now ready to be taken out but
workman should carefully note the layout of the leads before removing.
Six leads come out of the condenser unit. The two with the metal
shielding and a third in the same group, which has a brush clip on it,
are terminals for the governor breaker point condenser, and should be
on the left side. The other three leads, on the right side, are for the
filter condenser. The two filter condenser leads
without
1ugs are
connected across the line cord in the terminal insulation box (96) and
the third filter condenser lead
with
lug is connected to the motor
housing under screw 66.
19—B. To fit a new condenser unit start the two long shielded leads in between the
motor housing and field coil (44); then the three filter condenser leads
should be led down into terminal box space in motor case, and the condenser
unit pushed all the way up in the gear case housing (5). Do not cross
shielded leads over each other, or cross the filter condenser leads because
they are in the correct relation to each other. Connect the ground lead from
the filter condenser (the lead with the lug) under screw (66). Next replace
the terminal insulation box (96) and bring the field leads and condenser
leads up thru the holes provided. The leads may now be connected. Twist one
field lead, one filter condenser lead and one cord lead together and solder.
Then repeat the same with the other 3 leads, twisting and soldering. Fold
soldered leads into terminal insulation box (96) carefully to avoid grounds
and replace terminal insulation (95), terminal box cover (84) and screw
(87). Reassemble motor as in sections 9 to 14-A.
20. Radio Interference
Model 1 Automatic Mixmaster is equipped with a filter condenser similar to
that used in previous models. This part practically never requires
attention, but if there should be extreme radio interference, it may mean
the filter condenser needs to be replaced--proceed as in sections 19, l9-A,
and 19-B. Should the user of the Mixmaster prefer not to have the non—radio
interfering feature it may be removed by disconnecting the filter condenser
ground lead from the motor housing under screw (66) and taping the end of
the wire.

21-A. Contact breaker points (102) may be burned and do not make
contact; motor runs on current received thru resistor (43) only. Replace
governor (100) as in sections 5, 5-A, 13, 13-A, 13-B, 14, and 14-A.
21-B The Governor brushes (97) may be worn away. Repair as in sections
5, 5-A, 12, 13, 13-A, 13-B, and 14-A.
