Hi,
I have obtained a central heating water pump with its external wiring
damaged. The damage is minimal, its the small box on the side of the
pump which has been wrenched off, the small box contains a capacitor
and a small rotary switch labelled 1,2,3.
I have the small plastic box which was attached to the side of the
pump, and although it is a little damaged the capacitor looks Ok, and
the small rotary switch looks Ok. The screw holes are damaged but the
connecting wires are not damaged.
The connecting wires were attached with baby spade connectors, these
have pulled away without any damage.
Unfortunately there are six of them, and i don't know where they go.
Well, i know they go back to the six spade connections, but i don't
know which goes where.
I want to put this unit back into working order, so i will need some
help to try and figure out how the pump windings are connected.
Briefly:
Six wires coming from the pump/motor appear to be from three windings.
One of about 180 Ohms, and two of about 70 Ohms.
The windings are electrically independant of each other.
The capacitor is (i think) 2.5 Mfd, 1000 V. Wkg.
It is my guess that the higher impedance winding would be the shadow
and would go in series with the capacitor, unless someone thinks
otherwise ... ...
And that the two lower impedance windings would go to the switch to
be the 1,2,3 settings.
Presumably high medium and low.
The unit is only for 240 V mains, the windings are not for supply
voltage such as 110.
I will try to get some photos up and posted and maybe someone will
actually recognise the unit ... you never know.
Any help in sorting out these six wires would be much appreciated,
Regards, John
