generator operation and connections

A capacitor with the following markings was removed from a damaged air
conditioning unit. It has the following markings on the side

83-20 656

DIELEKTROL
No PCB's
CAPACITOR
MADE IN USA

97F4158
10uf
370VAC 60HZ
PROTECTED P921
A10000AFC
B509001P70
187C527H12

So I gather this is a 10 microfarad 370 volts alternating current
(max ) capable of sustaining usage on the 60hertz frequency that
120vAC house wiring generates. The unit is a chrome elliptically
shaped base and about 3.5 inches tall with two terminals each with
four connecting points (similar to those of a speaker terminal).
Since it had several wires attached to it I find myself uncertain as
to its operation.

I find it likely to be a filter for DC(one of the capacitor functions)
as it was connected to one of two or three possible switches on the
unit one of which is connected to the two shaft generator/fan.
I would appreciate further information as to the operation and
composition of this unit. Is the unit a single capacitor? Why are
there four connecting points to each terminal? What function does it
provide for the switch?
Of particular interest is the generator/fan unit; I would like to
able to power it direct from the AC line. The switch on the unit
appears to control several speeds yet I am not sure how to determine
which wire is which. I can hear the unit turn on but it will not
rotate. I did remove the capacitor and do wonder wether it is
essential for it to operate.
The wire colors are as follow blue, yellow, orange, red and black.
As for labels on the unit the following is written on the two labels:

8GC72
EG285330 1375

label 2:

KWAI CHOW ROTATION________
MODEL: B102
MADE IN CHINA 1100 RPM/0.8A/10MFD
115V 60Hz 3SP 1PH THERMALLY PROTECTED

C/N 11-14-90000-001 SER, J,- 565851
S217-00005-001 199

What do SP and PH stand for?
Further information on either or both units will be greatly
appreciated. At the very least I'd like to be able to figure out the
wiring connections so as to test properly. Any references will be
greatly appreciated.

Probably the fan motor run cap.

So I gather this is a 10 microfarad 370 volts alternating current
(max ) capable of sustaining usage on the 60hertz frequency that
120vAC house wiring generates. The unit is a chrome elliptically

But all the connecting points are shorted together so they are just
convenient tie points for all the wires.

Of particular interest is the generator/fan unit; I would like to
able to power it direct from the AC line. The switch on the unit
appears to control several speeds yet I am not sure how to determine
which wire is which. I can hear the unit turn on but it will not

It is for the fan.

The wire colors are as follow blue, yellow, orange, red and black.

Even mentions 10 uF.

SP=Speeds. PH=Phase.

Further information on either or both units will be greatly
appreciated. At the very least I'd like to be able to figure out the
wiring connections so as to test properly. Any references will be
greatly appreciated.

What are you attempting to do? Reuse the fan or other parts, or repair the
unit?

Be able to operate the unit direct from the power outlet. I am
unsure as to wether the capacitor is a necessary requirement for it to
operate; it appears to be powered on (from the distinctive
hum/vibration produced)without the unit; yet it will not rotate.

Thanks for the info

Yes, it is needed. You should have recorded the original wiring.
Without it, you'll probably have to do some experimenting at low
voltage to see which combinsations run the motor. There is no
standard color code for multispeed motors.

Typically, on the motor, there is a common wire that goes to AC Neutral.

Then, a wire that connects directly to AC Hot. From there, through
the (10 uF) cap to only one of the other wires, which one being
determine by the desired speed.
